Koh Lanta Diving Season

October and November: Slow Months

If you prefer diving in a quieter environment, then October and November are the best months to come to Koh Lanta.

February to May: The Best Time to Come for Diving

If you want the perfect diving conditions, then February to May is the perfect time to visit Koh Lanta. The waters are calm, and the visibility is excellent. And in April, tourism slows down, resulting in quiet dive sites where you can enjoy diving without disturbance. In May, the crowd is starting to disappear, and the island returns to its peaceful environment.

June to September: Unpredictable Weather

The weather condition in Koh Lanta from June to September can be unpredictable, resulting in dive shops staying around Koh Ha and Koh Phi Phi rather than venturing out to Hin Muang and Hin Daeng. Also, if the weather is not ideal for diving, dive trips may get postponed until the next day.

Whale shark: if you wish to spot a whale shark, they usually visit dive sites from November to April.
