May weather top tip

Still a very strong all-round month, the better beach weather more likely to be found on the eastern coast, however both sides are still promising plenty of sunshine.


May Overview

The good weather continues across the country, with temperatures likely to stay at their peak (avg temp: 30-35°C).  Across the north and central regions of Thailand, the chance of rain is on the rise, especially towards the end of the month (avg temp: 29-32°C).

On the beaches of the south, temperatures remain high (avg temp: 30-35°C) however the chance of rain on the west coast increases with the rainy season just around the corner.

Heavy rain would be unusual at this time of year, with short showers more expected, clearing the air and leaving bright blue skies. On the eastern side of the peninsula little, if any, rain is expected throughout the month.

Slash & Burn

During April and May you may witness the effects of 'slash and burn' farming used throughout Asia. New ground is cleared in February and, once dry, any wood and brush not required is burnt. Fires are lit across the country and particularly in rural regions this can create a hazy effect at times.
