Shanghai in August

One of the most oppressive months. Hot nights drag on and places without air conditioning are hard to bear. When a typhoon passes close, wind and rain pick up and flights can be delayed. Push outdoor plans to after sunset.

Days averaged 32°C and nights 26°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. Out of 31 days, about 8 brought rain; the rest stayed dry. The average is 8, but individual years ran from 2 (2006) to 15 (2009).

With 25 days above 30°C on average, most of the month felt like high summer. The warmest year was 2024, with highs averaging 34.8°C, 2.6°C above normal. Wet days did not mess around: about 19 mm each, the kind of rain that drives you into a doorway.
