Raise awareness of air pollution hazards in Hong Kong
Hong Kong's air quality in 2022 was the best in a decade, thanks to anti-pandemic measures that shut down much social and economic activity. You would not know it from pollution and reduced visibility this week.

A return to 'normal' last year, with slight increases in key pollutants, did not prepare us for plunging air quality in the past few days.
Pollution readings in more than 10 areas in Hong Kong reached the highest health-risk levels on Monday evening, as a dusty northerly airstream that picked up sand and dirt from mainland deserts brought pollutants that shrouded the city in haze.
Yeung Kwok-chung, senior scientific officer with the Observatory, said the last time Hong Kong was affected by such severe hazy weather was 15 years ago. The origins of the current pollution may have been beyond Hong Kong's control, but it is a wake-up call.
Despite incremental improvements over the years, good air quality that enhances Hong Kong's standing as an international financial hub and bridge to China cannot be taken for granted.

The pollution was compounded by the hottest day of the year, with temperatures reaching 33 degrees Celsius yesterday.

Hong Kong to issue T1 typhoon signal as early as Wednesday morning after hottest day of year
Hong Kong is set to issue the typhoon signal No. 1 as early as Wednesday morning, two days after experiencing the hottest day of the year. The Hong Kong Observatory said on Tuesday morning that an area of low pressure in the central South China Sea was forecast to develop into a tropical depression later that day or on early Wednesday. The storm is set to bring continued hot weather, while strong winds and heavy rain are expected later in the week. If it strengthens, the tropical cyclone will be called Wutip, Cantonese for 'butterfly.' The Observatory will also consider raising the typhoon signal to No. 3 later on Wednesday or Thursday, depending on how the storm develops. The No. 1 signal is the 'standby' signal. It is issued when a tropical cyclone is centred within about 800 kilometres of Hong Kong and may affect the territory. Hong Kong's first typhoon forecast in 2025 comes after the city recorded the hottest day of the year on Monday, with temperatures reaching a maximum of 34.3 degrees Celsius. The maximum UV index reached 12, an exposure level classified as 'extreme.' The 'very hot weather' warning, defined as temperatures generally reaching at least 33 degrees, is currently in force. According to the Observatory's forecast, temperatures are expected to range between 28 and 34 degrees Celsius on Tuesday, with a low chance of rain. The maximum UV index is also forecast to reach 12. Rain is expected in the latter half of the week into the next, the Observatory also said.

Heat warnings taken to heart as hajj reaches peak
Heat warnings taken to heart as hajj reaches peak Muslim pilgrims pray at dawn on Saudi Arabia's Mount Arafat. Photo: AFP Muslim worshippers prayed on Mount Arafat during the high point of the hajj pilgrimage as authorities urged them to avoid the hottest hours of the day after tragedy struck last year. Thousands of white-robed pilgrims recited Koranic verses from dawn on the 70-metre rocky rise near Mecca on Thursday, where the Prophet Mohammed is believed to have given his last sermon. But numbers thinned by midday following official warnings for pilgrims to stay inside between 10 am and 4 pm. Saudi authorities have taken steps to reduce the risk from heat at the hajj, which has drawn more than 1.6 million pilgrims to one of the world's hottest regions, according to fresh figures published on Thursday. Barring a few years of Covid restrictions, this hajj season has recorded the lowest number of pilgrims in over three decades. The dip comes after 1,301 people died in temperatures that hit 51.8 degrees Celsius last year – most of them illegal pilgrims, according to Saudi authorities, who implemented stringent measures to reduce their numbers this season. Unregistered, non-fee-paying pilgrims lack access to the full amenities offered during the hajj, including air-conditioned tents, making them particularly vulnerable to heat-related health risks. On Thursday, ice packs were handed to people walking towards Mount Arafat, with some placing the small bags on their heads. With temperatures reaching 42 degrees, officials ushered people away if they spent too long in one place near the bouldered hill, which had fans spraying mist and cool air at its foot. (AFP)

Tuen Ng festivities race off to a roaring start
Tuen Ng festivities race off to a roaring start Paddlers battle for glory in a dragon boat race in Sha Tin. Photo: RTHK Revellers erupted in cheers in tandem with the thunderous beat of drums and rhythmic slap of paddles across the city's waterways as dragon boat races ushered in early Tuen Ng Festival celebrations on Saturday with the traditional air of energy and excitement. The Observatory forecasted mainly overcast skies and one or two showers but that didn't dampen the paddlers' passion one drop. 'Are we confident about winning? Yes!," said a race participant in Stanley. "I am not worried about the rain," he said. "That's usual at Tuen Ng Festivals. "It's good for us to experience the 'Dragon Boat Water'.' Another group of paddlers said they had been practicing twice or thrice a week since December in the hope of winning their event. A woman brought her daughter back from the United States specially to watch the races. 'We are so excited because this is our first time, the first time seeing so many boats and so many people,' she said. Crowds also flocked to Tai O and Sha Tin for races, with Secretary for Housing Winnie Ho spotted among the throngs inundating the banks of Shing Mun River. In a Facebook post, Chief Executive John Lee sent his wishes for safety, health and good fortune to people in inviting everyone to watch the dragon boat races to experience the festive Tuen Ng atmosphere. More dragon boat racing action is coming next week, with the Hong Kong International Dragon Boat Races set to be held at Tsim Sha Tsui East Promenade.
