Hot Season
Expect hot dry weather from March / April thru June / July. Generally, temperatures will reach the high 30's C.. Rainfall is scarce, with some rare exceptions .. such as hailstorms in the North during Songkhran.Air quality in and around Bangkok deteriorates during the hot season. The Big Mango is not the best place to be during the hot season.
Rainy Season
Some call this the "Hot & Wet" season. The period of time just before a rainstorm can be especially uncomfortable because of temperature & humidity along with the absense of cooling breezes.Coastal areas and islands may be a bit more temperate, but escaping the heat is not absolute. A shady spot and cool drink is highly recommended. Thailand definately offers some rainy season advantages
Cool Season
"Cool" may be a bit of a misnomer to westerners. Temperatures dip into the 20's, but don't expect frost in the morning. The cool season may well remind you of a warm spring day or a cool summer day. Rainfall is rare .. but tourists are not.This is Thailand's high season. Resorts in popular destinations fill quickly. Prices increase. Road traffic increases. so are tef and sporadic showers are not While cool seasons tend to avoid some of the discomfort, uring the rainy season season varies a bit questions that travelers ask about Thailand's rainy season is, "Does it rain all day, every day during the rainy season?"
The answer is "No". In fact, many days during the rainy season are completely rain free. This rainy season, Cha am has had very little rain .. actually, not nearly enough.
A common scenario for the middle of the rainy season is a steady downpour at night, clear or overcast mornings and then some rain in the afternoon.
Also very common is one or two days of sunshine between wet days.
When does Thailand's rainy season actually start? In the North, it starts in June. The beginning and ending of the rainy season tends to migrate from Northern Thailand to Southern Thailand with a difference of about one month.
What that means, the rainy season in the North usually ends a month sooner than it does in the South. But then there is a complication in the South .. two rainy seasons.
Should the rainy season in Thailand be avoided? Definitely not. You can look forward to:
- Cooler weather
- Excellent white water rafting or river rafting
- Fresh air and green flora
- Avoiding the tourist surge
- Cheaper & more available accommodations
And if you don't need blazing hot sun to enjoy a beach .. you may find that you enjoy Koh Samui and Phuket even more.
