Hong Kong Heat Index at Wetland Park for the past 3 days

	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.
