Strange Weather

In this week at my place , the weather are changing so fast.Sometimes it can rain a whole day and for the next day it would be very hot. So I feel a little strange because at my country Indonesia it should be summer. Usually at summer it is very hot and it can't be rain. If have rain , it would be a very less.

Last week there had a heavy rain and after that some place were floating again.And I read the newspaper two days ago in the other country there had some problem too. I am scared it is because effect of global warming.
