Weather in Krabi
The weather in Krabi is dominated by two tropical monsoons; one bringing winds from the northeast, the other from the southwest. Typically this translates as two distinct seasons: hot and dry from November to April and, when the wind changes, cool and wet from May to October.
But the weather in Krabi is never that well-behaved! There can be rain during the ‘dry’ season, particularly at the start in November or December, as well gloriously sunny spells, sometimes for weeks at a time, during the ‘rainy’ season. The only thing that can be predicted with any degree of certainty is that it will be very, very hot in March and April (up to 37°C/99°F) and that the most rain will fall in September.
This means that the ideal time to visit the region is in January or February, when the weather in Krabi is nearly perfect - not too hot and with a only a slim chance of a downpour. This is, naturally, the peak tourist season, so you may find hotels and beaches full. Some people prefer to visit Krabi in the ‘rainy’ season, despite the risk of showers, as it is cooler, cheaper and less crowded - you can often have a whole island to yourself!
Booking a holiday between May and October remains, however, a gamble: while the typical rainy season pattern is of sunny days punctuated by a short, heavy afternoon shower, you could just as easily end up with ten days of straight rain - or sun! It’s hard to give concrete advice on weather in the Krabi area at this time, so we’ll just remind you that Krabi is beautiful whatever the weather.
