What Is the Weather Like in Hiroshima?

Hiroshima has strong seasonal contrast.

The Hiroshima climate by month shows average highs from about 43F (6C) in the coolest part of the year to about 86F (30C) in the hottest part.

Weather in Hiroshima changes the feel of the city because this is a place where comfort depends on more than the number on a forecast. A mild month can make metro transfers, neighborhood walks, outdoor meals, and photography feel easy. A difficult month can make the same itinerary feel slower, sweatier, colder, wetter, or more dependent on indoor breaks.

Best Month to Visit Hiroshima for Weather

What makes November stand out is balance. It is not necessarily perfect every day, but it usually gives travelers the best combination of outdoor comfort, manageable weather risk, and enough flexibility for a first-time trip. If hotel prices or crowds rise during this period, that popularity is at least partly weather-driven.

Rain is the main problem. The month is not impossible, but showers and damp conditions can interrupt outdoor plans and make transit transfers less pleasant.
