The weather in low season is pretty good most of the time, although the humidity is much higher than normal. We have the occasional rain shower during the day, but this usually lasts only for a short time. The visibility and current under water is not much different compared to the rest of the year. Many people prefer to dive in low season, because there are not as many boats and divers at the varies dive spots. Due to the location of our Phuket dive sites are we able to offer day trips year round from our Island.
