The average weather for Rawai, Thailand
Rawai and Phuket are classified as having a hot tropical monsoon climate, which means that there are two very distinct seasons; a dry season and a wet season. The dry season is from late November until early April with the reminder of the year classified as the wet season.
The tourist Season of Phuket and Rawai is from December through to March, this is the weather is at it’s best with hot sunny days and a gentle breeze to cool the nights. There is the chance of occasional rains brought in by the south westerly prevailing winds but the rains are very short and afterwards leave glorious sun. The temperature of the sea alters very little during the year and is between 26-28°C, very pleasant for swimming, snorkelling or diving in.
The flip side of all of this good weather is that Rawai experiences a very long and wet monsoon season that extends from May to October with September being the wettest month. The monsoon arrives from the south east and hits the Andaman coastline including Rawai weeks before mainland Thailand.
Do not visit Rawai or the west coast of Thailand during August through to October season, as the entire tourist industry shuts down while buffered by high winds and localised floods. For holidays between April to August consider the islands in the Gulf of Thailand which have a much later monsoon season.
