Latest Service Enhancement by the Observatory — Special Alert on Prolonged Heat

16 July 2022

Further to the upgrade of precautionary actions associated with the Very Hot Weather Warning last year, the Hong Kong Observatory took its service one step further today (16 July 2022): When high temperatures persist, the Observatory will push a new “Special Weather Tips” (see Figure 1) through the “MyObservatory” mobile app to alert the public for taking precautionary measures appropriate to their own conditions, e.g. sufficient water intake, taking rest, seeking help or medical advice. The same alerting message will also be promulgated on the website of the Observatory.


This summer sees hot night and very hot weather coming along wave after wave. Anticipating the mercury to rise again and stay high in the upcoming nine days (Figure 2), the Observatory reminds the public of potential threat to health under the heat and appeals for their high attention to body conditions. If symptoms such as dizziness, headache, nausea, shortness of breath or confusion develop, take rest and seek help immediately, and seek medical advice as soon as possible.
