Bangkok in July

Mid rainy season, with many wet and humid days. Around July the Buddhist Rains Retreat, Khao Phansa, begins and temples hold ceremonies. It follows the lunar calendar, so the date changes every year.

It was a hot month: 34°C by day and 26°C after dark. With 15 rain days on average, a wet day was rarely more than a few days away. A visitor in 2013 met 10 rain days; one in 2024 met 22. The average of 15 hid that gap.

31 days past 30°C made it a month for early starts and a long lunch indoors.
