If you are not bothered by rain and don't mind the a few cloudy days then choosing to come on vacation during the low season (March to October) could save you a considerable amount of money. Not only are flights cheaper at that time but many hotels and resorts will offer cut price accommodation and long-stay packages. Arriving in the low season also means that there are fewer tourists around and so there will be more room on the beaches and you will not necessarily have to book a hotel room in advance.
During the rainy/monsoon season there will be many rainless days and with temperatures in the south falling no lower than around 25°C, a beach holiday is still a good option. The oceans off the coast remain warm all year round. However, when swimming or snorkeling etc please pay attention to any warning flags and seek advice before entering the water as the seas can be dangerous at this time of the year due to strong currents and rip-tides.
Even if it does rain there are plenty of ways to keep yourself amused during the low season, below are just a few ideas:
Learn to cook Thai – it's a great time to explore the Foods of Thailand. There are many excellent Thai cooking schools around, ask for details at your local tourist information outlet. More on Foods of Thailand.
