Telangana Records 32% Excess Rainfall in 2024-25 Monsoon
Hyderabad: The 2024-25 monsoon season officially drew to a close, and Telangana emerged with a substantial 32% surplus in rainfall, ushering in optimism for the state's water resources and agricultural prospects. According to the latest data released by the Telangana Development Planning Society (TGDPS), the state received an impressive 1,215.9 mm of rainfall against the annual average of 918.9 mm, placing it firmly in the "excess" rainfall category. Meteorologists highlighted that this year's rainfall marked a significant improvement over the previous monsoon season, which saw lower precipitation levels. "The rainfall data compiled up to May 31, 2025, shows that a vast majority of districts across the state received above-normal rainfall, with several experiencing 'large excess' precipitation," said YV Rama, a senior scientist from TGDPS. Among the standout districts this monsoon were Wanaparthy, Jogulamba Gadwal, and Mahabubnagar—all of which were categorised under "large excess" rainfall. Wanaparthy recorded 1,136.9 mm of rain—an 80% increase over its normal of 631.4 mm. Jogulamba Gadwal wasn't far behind, logging 989.6 mm of rain, which is 71% more than its average of 579.6 mm. Mahabubnagar also received 1,099.6 mm of rainfall, representing a 71% deviation from its normal average of 643.2 mm. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like A perfect start needs the perfect ride – Shine 125! Honda Learn More Other districts, including Medak (32% excess), Rangareddy (29%), Karimnagar (28%), and Khammam (35%), also recorded significant surpluses, underscoring the widespread nature of the rainfall. Hyderabad, the state capital, saw 1,112.9 mm of rain against a seasonal norm of 830.7 mm, marking a 34% surplus. While this is expected to boost groundwater levels and provide relief for the city's water supply, officials also noted challenges. "We've witnessed more intense short-duration showers this year, which led to urban flooding and infrastructure pressure," said an official from the India Meteorological Department (IMD). Experts believe that the healthy monsoon could contribute positively to the upcoming agricultural cycle, particularly in water-intensive regions. "The excess rainfall is also expected to enhance reservoir storage and groundwater recharge, crucial for sustaining rural and semi-urban communities through the dry months ahead," said G Sailu, a biodiversity expert.

Summer cut short, monsoon on the horizon for Telangana
Summer has been cut short this year and the annual southwest monsoon could arrive as early as next week, bringing in isolated heavy rainfall throughout Telangana and Hyderabad capital region. Meteorologists at the Telangana Government Development Planning Society (TGDPS) informed that the region is already witnessing pre-monsoon showers and day temperatures have plummeted with the humidity being on the higher side due to the Easterlies from the Bay of Bengal. 'Rains could reach Telangana by next weekend unlike the usual June 7-8 schedule as this year's monsoon is expected to touch Kerala in the next few days probably in three to four days. We are likely to have a normal or above normal monsoon with El Nino phenomenon in a neutral condition,' explained senior weather consultant Y.V. Rama Rao on Wednesday. A low pressure area is found to be developing near the Arabian Sea and this could also help in the progress of the monsoon from Kerala towards the northwest direction, he said. The summer, this year, has been 'normal' with very few heat waves, as has been the case for the last five years. Due to the daytime heating, the region has also experienced thunderstorms during the evenings in the recent times, he pointed out. But, except for parts of north Telangana like Adilabad and other places where the maximum temperatures had reached upto 45 degree C in April-May, the trend has been of day temperatures being 3-4 degree C below the usual normal temperatures during the summer. Already, the day temperatures in the capital region has come down to 36 degree C and likely to fall further with the rains. During the summer this region saw temperatures reaching upto 42 degree C in some parts. In the districts too, the maximum temperatures have got reduced to 35-39 degree C in most places. The minimum or the night temperatures have been recording from 19-24 degree which is also few degrees below normal due to the cloud cover in most parts of the state. Usually the nigh temperatures creep upwards to 27 degree C during the summer, said Mr. Rao.

How much rainwater can be collected in a day from a 100 sq.m. rooftop? Enough for a family of four for at least 3 days
Hyderabad and its surrounding areas have been receiving rain for the past few days. How much of it could have been used for domestic purposes? People working towards rainwater harvesting said that if 25mm rainfall is received, around 2,000 litres can be collected from a rooftop spanning 100 square metres (over 1,000 square feet). On Friday (May 16, 2025) morning, the highest of 36.6 mm rainfall was received in Golconda, according to data from Telangana Development Planning Society. Stand alone apartments, gated communities, shopping malls and other structures with huge surface area can harvest several thousands litres of rainwater. Amount of water needed in a day Kalpana Ramesh, founder, The Rainwater Project said that a person needs, ideally, 130 litres of water a day. Around 2,000 litres of harvested rainwater would be sufficient for a family of four for at least three days. How is rainfall that can be collected from a rooftop calculated? Amount of rainfall that can be collected from a rooftop is calculated by multiplying surface area with rainfall As type of roof surface (soft with vegetation or hard), slope, debris, rain intensity, precipitation and other factors impact the rainwater collection, runoff coefficient too is included in the calculation. A 0.8 coefficient means that 80% of rainwater can be collected Formula: Surface area (in square metres) x rainfall (in metres) x runoff coefficient Example: If rainfall depth is 25mm over 100 square metres rooftop, then the rainfall collected is: 100 square metres x 0.025 metres x 0.8 = 2 cubic metres (2,000 litres) Groundwater level in Hyderabad The methods to recharge groundwater are under focus as the annual average water level in Greater Hyderabad Municipal Corporation (GHMC) continues to plummet dangerously: from 11.40 metres below ground level (bgl) in 2018-19, it dropped to 8.98 in 2024-25. And it was at 9.05 in 2024-25 till March. It continues to be in the red zone — which is below 20 metres bgl. The areas with Outer Ring Road where the water table is in the red zone includes Malkajgiri, Bachupally, Dundigal, Serilingampally, Hayatnagar, Abdullapurmet, Saroornagar and Kukatpally mandals. Filters can be used Vishwanath Srikantahiah from Biome Environmental Trust said that a sump, built to store municipal water, can also be used to store the rainwater. He said it has to be ensured that the roof is clean. When there is a forecast for rain, the roof can be cleaned. Filters costing around ₹3,500 can be used to filter rainwater. Ms. Kalpana said that inline filters are fitted in rainwater pipes. It weeds out leaves and other debris before collected rainwater is let into a sump or RWH pit. Rain throughout the year She said that as rainfall is not confined only to the monsoon, people will have sufficient water in non-monsoons too. According to TGDPS, the cumulative rainfall in GHMC from June 1, 2024 to May 15, 2025 was 996.5 mm against normal 811.8 mm. A contractor said that it takes around ₹15,000 to set up a RWH pit three feet wide and four feet deep, which needs maintenance.

Telangana under severe heatwave; Adilabad hits 45.5 degrees Celsius
HYDERABAD: Heatwave conditions continued to prevail across Telangana on Friday, with hot days and warm nights recorded in several districts. Parts of Nizamabad experienced heatwave conditions, while Adilabad saw warm night conditions. According to TGDPS, Adilabad recorded the highest maximum temperature at 45.5 degrees Celsius, followed by Nirmal at 45.4oC, Nizamabad and Jagtial both at 45.3 degrees Celsius. In Hyderabad, the maximum temperature touched 41.9 degrees Celsius in several areas. The IMD reported that a trough extending from central Chhattisgarh to the Gulf of Mannar—via northern Marathwada, interior Karnataka, and Tamil Nadu—remains positioned at 0.9 km above mean sea level. This system is expected to bring light to moderate rain or thundershowers across the state over the next six days. A yellow warning has been issued for warm night conditions on April 26 in isolated pockets of Adilabad, Kumurambheem Asifabad, Mancherial, Nirmal, Nizamabad, Jagtial, Rajanna Sircilla and Karimnagar districts. Additionally, a yellow alert for thunderstorms accompanied by lightning and gusty winds (30–40 kmph) has been issued for the next three days across several districts, including Adilabad, Mancherial, Warangal, Hyderabad, Rangareddy, Sangareddy, Khammam and others. For the next 48 hours, Hyderabad will experience partly cloudy skies with hazy conditions likely during morning hours. Light to moderate rain or thundershowers are expected towards evening or night. The maximum and minimum temperatures are likely to be around 39°C and 27°C, respectively. Surface winds will likely be southerly to south-easterly at speeds of 6–10 kmph. Markets wear a deserted look in Adilabad Residents are growing increasingly concerned about the impact of the heatwave and potential sunstroke. As a result, markets and public spaces in Adilabad have been deserted between 11 am and 6 pm. For the past two days, temperatures in several areas have consistently exceeded 45oC, prompting authorities to urge caution and advise people to stay hydrated and avoid going out during peak hours.

Telangana's heat divide: Why some districts are facing extreme temperatures than others?
In 2024, Telangana witnessed a stark contrast in how different regions experienced the summer heat. Nalgonda district endured a staggering 81 heatwave days — the highest in the State . Close behind was Suryapet with 54 days. In contrast, districts like Hyderabad, Hanamkonda, Medak, Adilabad and Rajanna Sircilla recorded no heatwave days at all, according to the Telangana Heatwave Action Plan 2025. The HAP using districts as administrative units is said to be the first of its kind. This uneven distribution, as per the report, is closely tied to topographical and climatic differences. Data from the last decade (2014-2024) shows that eastern and northern districts such as Mancherial, Jagtial and Peddapalli consistently record more than 10 heatwave days annually, while the western-central parts including Hyderabad, Medchal Malkajgiri and Rangareddy districts are at a higher elevation, and higher places generally stay a bit cooler, so they have fewer heatwave days. The report said that in India, heat wave conditions are considered if the maximum temperature of a station reaches at least 40°C or more for plains, 37°C or more for coastal areas and at least 30°C or more for hilly regions, as per the HAP report. To track and respond to these risks, the Telangana State Development Planning Society (TGDPS) uses data from 1089 automated weather stations across the State to issue district-level forecasts and advisories. The State's vulnerability map, created based on a decade of data, categorises mandals into five tiers — Severe, Critical, Semi-Critical, Vigilant and Safe. Six mandals fall under the 'Severe' category while 106 are marked as 'Critical' and 189 as 'Semi-Critical. Over 16.181 million people are in severe, critical and semi critical zones in the State. The plan's classification uses metrics such as the number of heatwave days and temperature anomalies over the past ten years. The Telangana State Heatwave Action Plan was initially prepared in 2016 following High Court orders and guidelines from the National Disaster Management Authority (NDMA). The plan was revised annually, with updates in 2017, 2018, 2019, 2020, 2021 and 2024, incorporating regular inputs from NDMA and scientific institutions. For 2025, Telangana's Revenue (Disaster Management) department has initiated the revision of heatwave preparedness in collaboration with the district administration of 33 districts, line departments, IMD, TGDPS and UNICEF Hyderabad field office.
