When is the best time to visit?

Semporna is a year-round diving destination, but the driest and calmest months are April to September.

• April–September: Flat seas with best visibility (20m–30m+).
• October–March: Occasional rain and choppier seas, but usually still diveable, especially around protected islands like Mabul and Kapalai.
• Note: July and August are peak season, so book well in advance.
