Like April, the Phuket Weather in May means a pretty hot month.
The weather in May is considered a ‘warm’ month of the year, so pack clothes and gear that accommodates warm conditions and maybe a light jacket and umbrella for any wet days.
It is important to note the rainy season begins at this time! Towards the middle of the month, the heat begins to taper as rainfall gradually increases.
NOTE: If swimming on the South or West Coast you should take extra care to check the lifeguard’s flags on the beach if RED, then don’t swim. Lifeguards normally designate safe areas, please for your own safety take notice.
