July is the month Bangkok gets its European summer visitors and its most important Buddhist holidays at the same time. The monsoon eases slightly to about 190 mm, the temperature settles at 32°C, and Asahna Bucha and Khao Phansa – the start of Buddhist Lent – bring candle processions, a nationwide alcohol ban and one of the most distinctive nights of the Thai year.
Asahna Bucha and Khao Phansa
Two consecutive days, falling on the full moon of the eighth lunar month – usually July, so confirm the 2027 dates locally.
- Asahna Bucha commemorates the Buddha’s first sermon. Thais take candles, incense and lotus flowers to their temple and walk three times clockwise around the main hall after dark. It is quiet, communal and genuinely moving.
- Khao Phansa, the day after, begins Vassa – the three-month rains retreat, during which monks remain in their monasteries. Traditionally communities donate candles and necessities to see them through it, and Ubon Ratchathani’s carved candle parade is the most spectacular version in the country.
- Many Thais stop drinking for the whole of Vassa, treating it as a period of abstinence.
Alcohol sales are banned nationwide on both days. Bars close, shops will not sell and hotel service is restricted. If you are in Bangkok for a specific night out, check the dates first.
Weather
July averages about 32°C by day and 26°C at night, with roughly 190 mm of rain. It is marginally drier than June and considerably drier than September, and the pattern is unchanged: bright humid mornings, a heavy hour or two late in the day, clear evenings.
The summer visitors
European and North American school holidays begin, and Bangkok fills more than it did in May and June – particularly as a stopover on the way to the islands. Rates rise from the June floor but stay well below the cool season, and the city never feels crowded the way it does in January.
One consequence worth knowing: the Gulf islands (Koh Samui, Koh Phangan, Koh Tao) have their driest weather from roughly February to September, which is the opposite of the Andaman side. If you are pairing Bangkok with a beach in July, the Gulf is the better bet than Phuket or Krabi.
What July is for
- Asahna Bucha and Khao Phansa, the most significant Buddhist nights of the year.
- Temples in the wet season – washed clean, green and far quieter than in winter.
- Good value, still well below cool-season rates.
- Island pairings, on the Gulf side.
- Indoor Bangkok, which is a genuinely world-class category of thing here.
Prices and crowds
Rising from the June floor but still low-season. The mid-year rush is nothing like the November-to-February peak, and Bangkok remains one of the better-value major cities in the world this month.

What to pack
Quick-drying clothing, shoes you can rinse, a compact umbrella, a dry bag and insect repellent. Temple-appropriate cover for shoulders and knees, and a layer for air conditioning. See what to pack for Thailand.

Frequently asked
What are Asahna Bucha and Khao Phansa?
Two consecutive Buddhist holidays at the full moon of the eighth lunar month, usually in July. Asahna Bucha marks the Buddha’s first sermon, with candlelit processions around temple halls after dark; Khao Phansa begins Vassa, the three-month rains retreat during which monks stay in their monasteries.
Why are the bars closed?
Alcohol sales are banned nationwide on both days. Shops will not sell, bars close and hotel service is restricted. Many Thais also abstain for the whole of Vassa, through to October.
How much does it rain in Bangkok in July?
About 190 mm, marginally less than June and far less than September, and almost all of it in heavy late-afternoon bursts rather than continuous rain.
Is July busy in Bangkok?
Busier than June, as European and North American school holidays begin, but nothing like the November-to-February peak. Rates rise off the June floor and stay well below the cool season.
Which islands are best in July?
The Gulf side – Koh Samui, Koh Phangan and Koh Tao – which has its driest weather roughly February to September. That is the opposite of the Andaman coast, so Phuket and Krabi are wetter now.
How hot is Bangkok in July?
About 32°C by day and 26°C at night. The cloud cover keeps it below the April peak, but humidity stays high throughout.
Is July a good time to visit Bangkok?
Yes, on value and atmosphere. The temples are quiet and green, the Buddhist holidays are the most significant of the year, and prices remain well below the cool season.
Can I still drink alcohol in July?
On all but the two holiday days, yes, normally. Just check the Asahna Bucha and Khao Phansa dates in advance if a particular evening matters to you.
