Hey,
In addition to what is said above, I agree that there isnt much wind here in Malaysia. I live in KL and study in Tassie, was expecting to kite here but since I got back I managed to kite once. And that was early Nov on the west coast, with a skim, and a 13m, im 70kg. The closest beach to KL is 1.5h away, past the airport. Morib, 'Gold Coast' and anything in between.
But the best chance to get proper wind now is to go to the east coast. Its been pumping (Malaysian standard) for the last two days now ranging 8-18 kts. You should look up wind forecast if you really keen on kiting (I normally use charts to see wind forecast movement/strength around South China Sea). Here is the local updates from Balok beach, (
http://balok-wind.com/). I think its fairly accurate.
As for waves, east coast is the best bet. I recommend Chendor beach which is 10 minutes drive north of Cherating beach. These two beaches are some of our surf beaches during the monsoon season (nov-feb). Cherating is a point break, but Chedor is a beach break. Should be open to clean wind. Balok is a beach break too but its too choppy. Its just about 15 mins south of Cherating. Tioman Island is another option. Clean wind and swells on the east side of the island. I normally go there for surfing. But I think it would be too much of an effort for you to go there.
You can rent surfboards in Cherating, and Tioman.
There is a lake in Putrajaya (30mins from KL) where I sail and people windsurf. Its not the 'high wind' season now. And the local authority has yet to approve kiting here. Might want to keep this in mind. I'm hoping they can do it soon so that I don't have to travel so far

Hope this helps.
