Usually, Hua Hin includes a very friendly climate all through the year. Whether it is in the rainy or monsoon season, the climate is always pleasant. You can find normally some rain events once in a while during the day, which never last for way too long. The night sky will usually clean up within some minutes and are time for a cooler weather.
The warmth can be slightly in April and could, here the next thunderstorm will be hot and you'll expect to get a great deal of sweat. Temperatures will increase about 93 degrees F (33.9 degrees C), however, the cool breeze in the beach will usually try and level temperatures being friendlier. To make things even cooler, often there is a festival in April, The Songkran. This can be known as the Water Festival, whereby people throw freshwater to one another as a means of cooling the surplus heat.
