Delhi on Wednesday experienced light rainfall at isolated stretches and also recorded spells of lighting accompanied by strong surface winds, prompting the authorities to issue a yellow alert for Thursday and Friday, according to the India Meteorological Department (IMD).
Officials said that there was no alert in place for Wednesday, but this was changed to a yellow alert during the day as gusty winds started approaching the Capital by late afternoon. They said heavy rainfall has been recorded in many areas across the country as the southwest monsoon is likely advancing towards the Arabian Sea.
IMD predicted a partly cloudy sky for Thursday, and a generally cloudy sky towards the evening. 'Very light to light rain accompanied by thunderstorm, lightning and strong surface winds during evening to night is expected. Wind speed may increase temporarily up to 30-40kmph, gusting to 50kmph, during the thunderstorm. The maximum and minimum temperatures over Delhi are likely to be in the range of 36 degrees Celsius (°C) to 38°C and 24°C to 26°C respectively,' an IMD official said.
Officials said the Capital could expect light rain on Friday and Saturday as well.
Rain and cloudy conditions since Wednesday afternoon brought down the mercury level, and winds in the evening gave the Capital a chilly feel.
The minimum temperature on Wednesday at the Safdarjung observatory, Delhi's base weather station, was 24.8°C, about 0.3°C below normal for this time of the year, but 2.1°C more than the minimum recorded a day before. The maximum temperature was 36.5°C, which was 2.8°C below normal.
IMD has forecast the maximum to remain in the 34-36°C zone on Thursday, but then increase by a couple of degrees over the next two days. However, no heatwave condition has been predicted for the next week.
Experts said the frequent rain spells in March and April can be attributed to the western disturbances hitting the northern plains more frequently this year.
'One after another, multiple western disturbances have been hitting the northern plains that are usually restricted to the lower Himalayas by the end of March. This, combined with cyclonic circulations from the Arabian Sea and moisture from Rajasthan side, are bringing frequent rains,' said Mahesh Palawat, vice president at Skymet.
He said that the scattered light rainy conditions, thunderstorms and winds are likely to continue for the next four to five days and the temperature is likely to stay below normal.
The wind and rain also helped reduce pollution levels in Delhi on Wednesday as the city recorded a 24-hour average air quality index (AQI) of 153 ('moderate'), according to the Central Pollution Control Board's daily national bulletin. The AQI was 141 ('moderate') the day before.
The Air Quality Early Warning System (AQEWS) for Delhi has forecasted the AQI to stay in the 'moderate' category until Saturday at the earliest.
'The air quality is likely to be in the moderate category from Thursday to Saturday. The outlook for the subsequent six days is that the air quality is likely to be in the moderate category,' the AQEWS bulletin said on Wednesday evening.

When a flat tyre took me closer to ‘Young India'
I wish to share a heart-warming incident my wife and I recently experienced. On May 25, we were returning to the city after dropping our son at the Kochi international airport. The IMD had warned of a stormy night. By 9pm, we were indeed witness to it — furious splashes of rain cascading down the windshield. In spite of the wipers' valiant effort, visibility on that busy stretch of the highway was reduced to mere yards. Though, as a youth, I had once harboured a Wordsworthian wish to stand and stare at nature's fury, that night I had but one singular wish: to support my co-passenger's understandable wariness of the treacherous thoroughfare. Suddenly, a flash, a thunder. But my experienced hands on the wheel realised — it was not thunder alone. Pulling over at a dark alley confirmed my fear: a flat tyre. As I broke the news to my better half, it brought back memories of a night years ago when, stranded in a similar alley (albeit without a storm), I had changed a flat tyre of our two-wheeler with both our children on board. But time weakens not only the body but the resolve too. The will to even lift the spare tyre seemed to have ebbed. Confronted with those old anxieties, what unfolded next felt like a vision I had long held for our country. A Tagorean dream of a young India. Without being overly dramatic, let me describe the event that followed. This occurred just a few yards from the Pullinchode signal junction in Aluva.

Why you might not to able to lower your AC temperatures below 20°C in India
Union Power Minister Manohar Lal Khattar said on Tuesday that the government is planning to introduce a fixed temperature range for air conditioners. Under the proposed rule, ACs will be set to operate between 20 degrees Celsius and 28 degrees Celsius, which means they cannot cool below 20 degrees Celsius or heat above 28 degrees Celsius. The move aims to help manage energy use in homes and offices, especially as electricity demand rises and heatwaves become more frequent and intense read more The temperature standardisation for ACs will be set between 20°C to 28°C. Image: AI Generated/Representational Air conditioners in India may soon be limited to cooling only up to 20 degrees Celsius and heating no more than 28 degrees Celsius. Union Power Minister Manohar Lal Khattar announced on Tuesday that the government is preparing to bring in a fixed temperature range for ACs. The Centre's new rule will apply to all air conditioners, whether used at home or in workplaces. ALSO READ | How many air conditioners do Indians buy a year? STORY CONTINUES BELOW THIS AD Many countries have already brought in similar limits, either through official orders or public guidelines, especially in offices and public spaces where power use is high. In this explainer, we look at what the government is planning, why this change is coming, what it means for people in India, and how it lines up with rules in other countries. Let's take a look: What is the new plan? How will it work? At a press briefing held in New Delhi, the Union Minister said, 'Regarding air conditioning standards, a new provision is being implemented soon. The temperature standardisation for ACs will be set between 20°C to 28°C, meaning we won't be able to cool below 20°C or warm above 28°C.' 'This is a first-of-its-kind experiment, aiming to standardise temperature settings,' he added. At present, people usually set their air conditioners between 20°C and 22°C. However, the ideal comfort level, according to standard guidelines, is between 24°C and 26°C. The plan will be rolled out shortly, with checks in place to see how well it works. The aim is to encourage consistent use of ACs and cut down the high electricity usage caused by extremely low cooling settings. The Centre's order will fix the temperature range for all air conditioners, whether at home or in businesses. This means that once the rule takes effect, users would not be able to drop the cooling below 20°C or raise the heating past 28°C. Right now, many ACs sold in the market allow temperatures as low as 16°C or 18°C and heating options that go up to 30°C. STORY CONTINUES BELOW THIS AD At present, people usually set their air conditioners between 20°C and 22°C. Reuters/File Photo Under the new rule, manufacturers will have to either update the software or change how the devices are programmed to follow the 20°C–28°C limit. While the government has said the change will be watched closely, details on how it will be enforced across different sectors are yet to be shared. Why did the government take this step? This move is meant to manage how energy is used in homes and offices, especially as India faces growing electricity demand and more frequent, severe heat waves. Union Minister Khattar called it a 'bold step' to tackle the habit of using air conditioners at very low temperatures, which leads to a lot of power being used. The numbers behind the decision are strong. Even a one-degree rise in AC temperature can lower energy use by about 6%. If the country sets the minimum temperature at 20°C, officials believe it could save up to 3 gigawatts of peak demand, Pankaj Agarwal, the ministry's top official, told Hindustan Times. This change also fits into a wider national push for using energy in a more balanced way. As more people from the middle class buy air conditioners and cities grow, electricity use is rising sharply during the summer months. STORY CONTINUES BELOW THIS AD Running ACs at very low temperatures puts huge pressure on the power supply system. The Bureau of Energy Efficiency (BEE) said most people in India tend to set their ACs at 20–21°C, lower than needed for basic comfort. This not only increases power bills but also leads to more pollution, as much of India's electricity still comes from coal-based plants. By setting a lower limit of 20°C for cooling and 28°C for heating, the government wants to make ACs more efficient, reduce the pressure on the electricity grid, lower emissions, and shift how people think about using cooling systems. The aim is not just to change how machines work, but to change how people use them, encouraging smarter, more responsible choices. A study from the University of California, Berkeley, found that tougher energy-saving rules for ACs could help India avoid 60 gigawatts of extra electricity demand by 2035. This could also save up to 7.5 trillion rupees ($88 billion) in the cost of building new power plants and grid systems. STORY CONTINUES BELOW THIS AD This change also fits into a wider national push for using energy in a more balanced way. Reuters/File Photo How will it impact Indian consumers? How much electricity will you save? The Bureau of Energy Efficiency has been pushing for better air conditioning habits for years. Their data shows that raising the AC temperature by just one degree can cut power use by around 6%. That means going from 20°C to 24°C could save up to 24% in energy use. Over the course of one summer, this could lead to much lower electricity bills and take a big load off the power grid. Many people may not realise that cooling a room to 16°C in a hot, humid country like India is unnecessary, and not great for your health. Experts say the best temperature for comfort indoors is between 24°C and 26°C, especially when you account for humidity, fresh air, and regular indoor clothing. These new rules, then, match closely with actual comfort levels. They do not force people to feel too warm; they just push for more sensible, healthier use of air conditioners. What health experts are saying While the move is largely focused on climate and energy concerns, health experts point out that it could also have real benefits for the body, especially during the harsh summer months when many rely heavily on air conditioners for relief. Dr Suranjit Chatterjee, a senior consultant in Internal Medicine at Indraprastha Apollo Hospital, told India Today that setting air conditioners at very low temperatures can interfere with the body's natural ability to manage heat. 'When you're sitting in a very cold environment and then suddenly step outside into 44 or 45 degrees, your body experiences a temperature shock… This transition can trigger colds, fatigue, or even stress the internal organs,' he told the publication. STORY CONTINUES BELOW THIS AD Though the government's guideline fixes the minimum setting at 20°C, Dr Chatterjee advises going a bit higher. For most people, he recommends keeping the AC temperature between 22°C and 24°C. How India's plan compares to global norms India's move to fix air conditioner settings between 20°C and 28°C follows a global pattern where many countries are trying to control indoor cooling to save energy and reduce emissions. Some have made these rules official, while others treat them as strong recommendations. Italy has set a minimum of 25°C for cooling in public buildings like schools and post offices. This step was taken to cut down on energy use and emissions in line with EU climate goals. The Bureau of Energy Efficiency has been pushing for better air conditioning habits for years. Image: AI Generated/Representational In Japan, the Ministry of Environment advises keeping air conditioners at 28°C during the summer, especially in workplaces. Though not a law, this is supported by public awareness drives and is accepted widely in corporate settings. In the United States, there is no fixed rule, but the Energy Star programme suggests keeping air conditioners at 25.5°C (78°F) when people are home. These guidelines are backed by incentives and campaigns led by power companies. China has made it compulsory to set the cooling at no less than 26°C in government offices during summer. Non-compliance can result in penalties, at least in public buildings. Spain took a stronger approach in 2022. It passed a law requiring public places, offices, and commercial buildings to maintain cooling at no lower than 27°C. This was part of a larger plan to cut energy use and address the rising cost of power. STORY CONTINUES BELOW THIS AD Australia does not set limits on thermostat settings. Instead, it focuses on how efficient the AC units are. Through its Minimum Energy Performance Standards (MEPS), only devices that meet energy-saving rules can be sold. While offices and state guidelines often suggest keeping the temperature between 22°C and 24°C, these are not enforced by law. In Belgium, public buildings are required by law to keep cooling at no less than 27°C in summer and heating capped at 19°C in winter. This is part of a national push to use energy more responsibly. Compared to these examples, India's 20°C to 28°C range gives more room for adjustment. While countries like Spain and China focus only on public spaces, India's rule is expected to apply across homes, businesses, and industries. In doing so, India is not only following global trends but also aiming to take it a step further by setting a uniform rule that reaches all users and encourages a long-term shift in how cooling is used.

After two-week pause Southwest monsoon set to become active starting Thursday
New Delhi [India], June 11 (ANI): The Southwest monsoon rainfall over India, which had stalled for nearly two weeks after the early onset this year, is likely to become active again starting Thursday. The India Meteorological Department (IMD), in its latest update, forecast heavy to very heavy rainfall at a few places and extremely heavy falls at isolated places over south peninsular India during June 12-15 and over Konkan and Goa on June 13 and June 14. In the same update, IMD forecasts that heat wave conditions are likely to continue over Northwest India, with severe heat wave conditions at isolated pockets over West Rajasthan until Thursday and abate thereafter. The southwest monsoon hit Kerala on May 24, a week earlier than usual, marking its earliest arrival on the Indian mainland since 2009. The normal onset date for the southwest monsoon is June 1. May 2025 was the wettest since 1901 in India, with the country receiving an average rainfall of 126.7 mm last month. The early onset of the southwest monsoon brought continuous rainfall across southern and eastern India, contributing to this record. After an early onset, the progress of monsoon had stalled, reportedly on May 29, only to be active starting Thursday, as is expected by the state-run weather office. Monsoons are a key indicator that helps analysts gauge the economic outlook of the country's manufacturing and agricultural sectors. The IMD forecast southwest monsoon rainfall over India to be 106 per cent of the Long Period Average. This projection is more than the 105 per cent forecast in the April update. The long-period average rainfall in India is 868.6 mm. The IMD said that above normal rainfall is most likely over the country as a whole during the monsoon season (June to September) 2025. Region wise, the southwest monsoon rainfall is projected to be above normal over Central India and South Peninsular India (>106 per cent of Long Period Average), normal over Northwest India (92-108 per cent of Long Period Average) and below normal over Northeast India (94% of LPA).>94 per cent of Long Period Average). The state-owned weather office said the country's average rainfall in the month of June is most likely to be above normal (>108 per cent of the Long Period Average). IMD will issue the July rainfall forecast in the last week of June. The country has received excess rainfall so far this season. The monsoon has onset early on two occasions during the past five years --2022 and 2024. In 2022 and 2024, the monsoon onset was May 29 and May 30, as per IMD data. IMD has been issuing operational forecasts for the date of monsoon onset over Kerala from 2005 onwards. The monsoon has onset early on two occasions during the past five years --2022 and 2024. In 2022 and 2024, the monsoon onset was May 29 and May 30, as per IMD data. IMD has been issuing operational forecasts for the date of monsoon onset over Kerala from 2005 onwards. IMD's operational forecasts of the monsoon onset date over Kerala during the past 20 years (2005-2024) were correct except in 2015. Forecast verification for the recent 5 years (2020-2024) is in the table below. Above-normal monsoon rains help farmers to sow more crops this Kharif season, which bodes well for the overall agriculture sector. Agriculture is the mainstay source of livelihoods for millions of Indians. Traditionally, Indian agriculture, especially the Kharif season, relies heavily on monsoon rainfall. (ANI)
