Why are Surabaya is so hot?

Oh my God, what's wrong with Surabaya? When Surabaya not hot like this? It's so hot, you know? Hahaha. How i can enjoy my holiday if Surabaya almost hot every day? I don't understand why Surabaya always hot lately. I think Surabaya in the past is not so hot like this. Maybe it happened because now Surabaya has to much high rise building but the fewer park. Come on! If the governor more carefully with Surabaya, please try to build some park in Surabaya so the weather is not so hot like this. Peace! :D
