Bangkok in March: The Heat Arrives, Crowds Thin, Prices Drop, and How to Do It Well

March is when Bangkok's hot season begins: dry still, but mid-thirties by day and climbing through the month. The crowds thin and prices drop, which makes it a good month if you plan around the heat. Weather by week, what's on, how to structure a day, what to pack, and end-of-March versus the start.

February is kinder; April is hotter still. Weather by month.

The hot-season day#

6:30 to 11 Temples, markets, the river, Ayutthaya. 11 to 4 A pool, a mall, a massage, a long lunch, a nap. The whole city does this. 4 to midnight The canal boat, Wat Arun at golden hour, Chinatown, a rooftop, a night market. Bangkok at night is March's best guide.

What's on#

Fewer festivals than the months either side. The art fairs and the start of the mango season (the best mango sticky rice of the year). Chatuchak early on a Saturday before the roof turns it into an oven.

Crowds and prices#

Shoulder season begins: the Grand Palace is noticeably quieter after the first week, and hotels drop from high-season rates. Where to stay, ideally with a pool; Bangkok on a budget.

What to pack#

The lightest clothes you own, two sets a day, temple cover in the bag, a hat, electrolyte sachets from any 7-Eleven. What to wear in Bangkok.

Plan it#

The 3-day itinerary, rearranged for the heat. A Bangkokian knows where the city goes between noon and four; post your dates on Roavi Community and a Local Friend can show you.
