It's travelling 101 that the low season is bound to grant the lowest prices that one could get at any destination and Hua Hin in Thailand is no different. So, if you are keen on pulling off your Hua Hin getaway on the lowest budget possible, the low season would be the ideal time for your visit, which is more or less, from May through September. The low season wouldn't only grant you incredibly attractive prices, but also a much more pleasant atmosphere free from overwhelming crowds. However, it is possible that you might encounter a few rainy days during this time of the year, but in a tropical Southeast Asian destination such as Hua Hin, it surely wouldn't be the worst thing in the world.
