Thailand does not really have any four seasons but rather three weather periods along the lines of the Cool Season (November—February), the Hot Season (March—May), and the Rainy Season (June—October). Generally, guide books advise Thailand travelers to choose the East coast from April through September and the West coast the rest of the months — something that is a qualified truth, though.
Hua Hin is known as the “dry city”, of course due to the fact that it normally gets substantially less rain than other parts of Thailand. Having said that, May 2007 came as a surprise to most locals and tourists, with almost as much rain as during the whole of the Rainy Season in no more than a week.
Below, average temperature and rainfall per month in Hua Hin are listed:

Hua Hin’s Hot Season ranges from March to June with an average temperature of 30 degrees Celsius. However, luckily enough, most hot days in Hua Hin are blessed with a cooling breeze — of course to the best liking of all the sunbathers normally present on the city’s beaches. This cooling breeze, often particularly strong in the afternoon, distinguishes Hua Hin from many other Thai resort destinations.
The Rainy Season in Hua Hin starts in July and continues until October. With an average temperature of 28 degrees Celsius, the days are slightly cooler than during the Hot Season. In spite of its name, it is not raining every single day — and once it is, we are rather talking about showers (though quite intense indeed at times!) than continuous raining.
During the lovely Cool Season, the average temperature goes down to some 26 degrees Celsius. This season more or less exactly coincides with the tourist high season, that is November through February. Honestly, it is not very hard to see why Northern Europeans chose to swap nasty snowy weather for Hua Hin’s near-perfect “winter” climate.
