Cold and Very Hot Weather Warnings

Hong Kong experiences both hot and cold seasons. The Observatory maintains a close watch on the local temperature changes. It issues warnings whenever Hong Kong is threatened by cold or very hot weather, to alert members of the public to the danger of low body temperature or the risk of heatstroke and sunburn due to cold weather or very hot weather respectively.

Once issued, the warnings are broadcast over radio and television. If necessary, the Observatory will hold press briefings, through which members of the public are reminded to take necessary precautions.

If cold or very hot weather persists, the Observatory will repeat the special announcements while the corresponding weather warning is in force, to remind the public to take necessary actions.

These warnings also alert relevant government departments, such as the Social Welfare Department and the Home Affairs Department to consider the need to take actions, such as the distribution of blankets and the opening of temporary shelters.

It is important that members of the public take note of these warnings and take steps to protect themselves and their family against cold or very hot weather. For an update on the status of weather warnings, the public may listen to radio and television broadcasts, or call the Observatory Dial-a-Weather service, or the Observatory Internet homepage.

  2. If you must go out, avoid prolonged exposure to wintry winds.
  3. If you know of elderly or persons with chronic medical conditions staying alone, call or visit them occasionally to check if they need any assistance.
  4. 4. Make sure heaters are safe before use, and place them away from any combustibles.

  1. When engaged in outdoor work or activities, drink plenty of water and avoid over exertion. If not feeling well, take a rest in the shade or cooler place as soon as possible.
  2. Avoid prolonged exposure under sunlight. Loose clothing, suitable hats and UV-absorbing sunglasses can reduce the chance of sunburn by solar ultraviolet radiation.
  3. Swimmers and those taking part in outdoor activities should use a sunscreen lotion of SPF 15 or above, and should re-apply it frequently.
