Osaka in July The wettest month of the year, and once the rains end the heat hits at once. Tenjin Matsuri on July 24 and 25 is counted among Japan's three great festivals, with a boat procession and fireworks on the Okawa River. Crowds are huge, so allow extra travel time.
Osaka in July ran hot: 32°C by day and 25°C at night. By midday the shade was the best seat in town. With 11 rain days on average, a wet day was rarely more than a few days away. Year to year it swung widely, from 5 rain days in 2008 to 20 in 2020.
With 23 days above 30°C on average, most of the month felt like high summer. July 2025 averaged 36.0°C by day, 3.7°C above the 20-year mean. Wet days did not mess around: about 19 mm each, the kind of rain that drives you into a doorway.
