What time of year can you see bioluminescent plankton in Thailand?


Coming to Railay Beach, Krabi during the high season (November to April) can increase your chances of seeing the plankton. Going on a clear, moonless night is highly recommended.

​

The bioluminescent plankton are easier to see during the time just before, during, and just after the start of the new moon because it’s darkest. So, the best times of 2023 will be during November and December of 2023, but really anytime around a new moon can produce the awesome result you’re looking for!

New Moon Dates for 2025
