Which is the best month to go to Semporna?

The best turtle viewing season is from May to September every year

Semporna is a county in Tawau Province, Sabah, Malaysia. The population in 2006 was 133,000. Semporna literally means perfect in Bajau and Malay. The town is surrounded by sea water, and Semporna and its affiliated islands are like a dream island in the real world. This is a diving resort with many excellent diving bases around where you can learn various diving courses.

But now it is somewhat overdeveloped, so the environment has become less "perfect" and people are starting to look for better places to experience the fun of diving.
