The climate of Hiroshima (Japan)
Hiroshima was one of the two cities that were hit by an atomic bomb on August 6. The city still commemorates this event with the Atomic Bomb Dome. After the atomic bomb the city got hit by a typhoon in September. After these two destroying events the city had a long period of rebuilding ahead. All the old buildings and gardens were destroyed by the atomic bomb. Several sights have been rebuilt and can be visited today.
Hiroshima has a warm maritime climate. This type of climate is characterized by rainfall all year round. Winters are mild and subzero temperatures are uncommon. Spring and summer are warm. Most of the rain falls in June and July. High humidity figures are responsible for an unpleasant feel during the summer. Tropical storms are not uncommon in Hiroshima in August and September.

More climate information
Climate figures are very useful but don’t present a general impression of the climate and the eventual weather circumstances within a certain period. The figures don’t always reflect the chance of wintry weather, extreme heat or hurricanes. That is why we offer useful extra climate information for each month of the year:
