It appears from today's hot weather that summer is finally here. April to June is fine but Hong Kong is forbiddingly hot and unbearably humid from July through to September. The hottest period of summer is not helped by the wind blowing from Mainland China, bringing the pollutants from the manufacturing boom towns to here. No wonder when Hong Kong was still Her Majesty's colonial land, the summers saw most members of the British ruling class fly back home to hide in their personal castles by the sidewalks, er, pavements. For the locals, taking a spin on their bikes or chewing popsicles are probably great ways to chill out from the heat.
