Hanoi in August The month with the most wet days. A typhoon can cancel Ha Long Bay cruises or hide the scenery in mist. Leave slack in your schedule. Heavy rain also slows getting around the city.
Days averaged 33°C and nights 26°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. Rain was a regular part of the month, showing up on 23 days on average. The driest year, 2013, had 19 rain days; the wettest, 2010, had 28.
Highs topped 30°C on 27 days of the month on average. Mixing in indoor stops at midday made sense.
