Hong Kong has issued its first “very hot weather” warning of the year, with the city expected to endure a heatwave through Friday.

The Hong Kong Observatory (HKO) issued the warning at 7.45am on Tuesday, with the mercury expected to reach 35 degrees Celsius.

The warning is triggered when the mercury is set to reach, or exceed, 33 degrees Celsius. As of around 1:30pm on Tuesday, Cheung Chau was seeing temperatures of 32.1 degrees Celsius.

The city recorded its hottest day of the year on Monday, as temperatures hit 32 degrees Celsius.

The HKO has alerted the public of the risks of heat stroke and sunburn.

The heatwave is expected to continue through to Friday, as an anticyclone aloft brings very hot weather and low pressure to the coast of Guangdong, according to the HKO.

Highs of 33 degrees Celsius are predicted between Tuesday and Friday, while the lows will range between 27 and 29 degrees.

Hong Kong may see showers during this weekend, as temperatures dip slightly to 26-30 degrees Celsius.

The Intergovernmental Panel on Climate Change has warned that the intensity and frequency of heatwaves have continued to increase since the 1950s due to human-caused climate change. The prevalence of greenhouse gases like carbon dioxide – which trap heat in the atmosphere – raises the planet’s surface temperature, with hotter, longer heatwaves putting lives at risk.

Hong Kong has already warmed by 1.7 degrees Celsius since the Industrial Revolution, research NGO Berkeley Earth says. Heat and humidity may reach lethal levels for protracted periods by the end of the century, according to a 2023 study, making it impossible to stay outdoors in some parts of the world.

In a Tuesday statement, the Centre for Health Protection of the Department of Health reminded members of the public to hydrate regularly, and to avoid strenuous exercise and prolonged activities such as hiking.

It also suggested that outdoor or manual workers should reschedule work to cooler hours as far as possible.

Nevertheless, as of Tuesday lunchtime, the Labour Department had not yet issued a heat stress warning – a three-tier warning system introduced in 2023 to help protect Hong Kong workers from heatstroke. 

Outbound travel during long weekend

Hongkongers enjoyed a three-day weekend, with Monday marking Buddha’s Birthday.

According to the Immigration Department, Hong Kong residents made over 615,000 outbound journeys on Saturday, with over 557,000 travellers heading northbound to Shenzhen and other destinations in mainland China.

The figure marks a week-on-week increase of 36.7 per cent.

From Friday to Monday, Hong Kong residents made nearly 1.87 million outbound trips – a rise of 30.8 per cent compared to the same period last week.

Stay salty, everybody.

Shibuya is one of Tokyo’s most exciting neighborhoods. Between world-famous tourism landmarks like the statue of faithful dog Hachiko and the scramble intersection, plus shopping options from iconic stores like fashion mecca 109 and Nintendo Tokyo, there’s a lot to see and do in this part of downtown, and if you’re visiting this summer you might want to stop by the Shibuya Ward Office too and grab a little something to eat.

No, this isn’t another semi-secret ward office cafeteria we’re talking about. Instead, the Shibuya Ward Office is giving out free sodium tablets as of June 1.

Shibuya Ward’s goal isn’t to promote snacking, though. The complimentary salt tablets are part of Good Sweat Shibuya Action, a multi-faceted public awareness campaign aimed at dealing with the high heat and humidity that come with summer in Japan. While it might not be as much of an issue in countries with higher salt intakes in their daily diets, in Japan profuse sweating leading to dangerously low levels of sodium in the body is a legitimate concern for many people, with supplements for replenishing sodium and other vital minerals lost during perspiration, such as Kabaya Foods Corporation’s Enbun Charge Tablets being sold in pharmacies and convenience stores.

However, not everyone carries a supply of tablets on them, and as the effects of heat stroke can sneak up on people, Enbun Charge Tablets are now being offered free of charge at the Shibuya Ward Office. Anyone who wants one can simply grab a tablet from the box located in the second-floor atrium of the building.

Boxes of free sodium tablets will also be placed at 29 other locations in Shibuya Ward, primarily libraries, public gyms/sports facilities, medical centers, and government offices, tying into the ward’s initiative to promote “cool sharing spots,” climate-controlled common-use areas where a large number of people can cool off in a more aggregately energy-efficient manner than simultaneously running their own home air conditioning units.

As the tablets are individually wrapped, there’s no need to use them right away, so swinging by the ward office and grabbing one to keep on hand for later in the day is an option too.
