Bangkok's Hot Season
If you happen to linger in Bangkok 'til march, prepare to sweat. Breezes diminish and temperatures crawl past 33°/90°. And very little relief from scarce rainfall.
That's when you begin to realize that Bangkok is mostly concrete and steel. Heat lingers and seems to compound. You forget about tuks-tuks and ask every taxi driver is his air-con is working.
Welcome to Bangkok's hot season. It will las from March until May and get especially uncomfortable during mid April (34°/95°) . The Songkran water festival will only last about 3-5 days and you won't mind getting drenched.
The good news, hotel rates are cheaper and more rooms are available. But public transportation gets jammed. Don't even think about traveling outside Bangkok just before and after Songkran. Why do you think those Thais are hanging outside windows and roof hatches of trains?
Just enjoy Bangkok during Songkran. Besides the water tossing, you can actually get to your destination in a reasonable time. Bangkok traffic will never be this good again for another year.
Bangkok's Rainy Season
Bangkok's rainy season takes travel misery to a new level. Expect to experience.
- A scarcity of Taxis
- Ankle-deep water at the curbs
- Gridlock at rush hour
Rainy season in Thailand varies a bit by region. Basically, the rainy season starts earlier in the North than in Bangkok. Wet season in Bangkok actually starts at the end of the hot season.
The rainy season has two peaks. The first is in May with average rainfall over 200 mm. Then in September tropical storms dump over 300 mm on Bangkok.
Getting around in Bangkok will be a significant challenge. Learn all you can as quickly as you can about Bangkok's subway and Skytrain. Learn the stations with covered pedestrian access directly into shopping malls.
So if you plan to visit Bangkok during the rainy season consider taking along some appropriate rainy season clothing.
