Remark :
(i)

The Hong Kong Heat Index was calculated from the measured Natural Wet Bulb Temperature (Tnw), Globe Temperature (Tg) and Dry Bulb Temperature (Ta). Its value is given by 0.80Tnw + 0.05Tg + 0.15Ta. Generally speaking, the public should take appropriate precautions when the index at King’s Park reaches around 30 or above to prevent from adverse health effects brought by hot weather.Reference : K.L.

(ii)

To maintain data reliability, the heat stress monitoring station will undergo brief maintenance and consumable replenishment every few weeks. Data updates may be temporarily suspended at that time.
(iii) The data displayed above is provisional. Only limited data validation has been carried out.
