Hiroshima in June

The rainy season begins and rain increases. The Tokasan Festival in early June fills the center with people in yukata. Bring an umbrella. It turns muggy as humidity rises. Trams are handy when it pours.

Days averaged 27°C and nights 20°C. Midday was for air conditioning, a cold drink or a long lunch out of the sun. There were 11 rain days on average, roughly one day in three. Individual years ran between 6 and 14 rain days.

About 5 days a month still climbed past 30°C, the ones where you looked for shade. Rain days averaged 21 mm each, so when it rained it rained properly.
