Why is JB/SG better than KL

The last weekend I spent in Klang Valley made me realise something really important. The weather there is so hot, and if you are outdoors it is like a oven turned on to the max. While being in Singapore or JB, early morning walks can be such a pleasant journey because most often the sun is shining, and there is cool breeze blowing... and usually the weather follows till afternoon.. it could get more sunny, but the wind is very cooling and makes walking under the sun a pleasure. Definitely this weather has not always been here, perhaps it is the global warming causing such conditions here, whatever it is, at the risk of sounding selfish, I'm loving it!
