Hiroshima Weather & Climate Guide 2026

Month-by-month weather, best times to visit, and what to pack for Hiroshima.

Hiroshima is one of Japan's most historically significant cities, forever linked to the atomic bombing of August 6, 1945, yet reborn as a vibrant modern metropolis and a global symbol of peace and resilience. The city sits on the delta of the Ota River where six channels meet the Seto Inland Sea, giving it a lush, island-laced setting. Beyond its profound memorial sites, Hiroshima offers excellent cuisine — including the iconic layered Hiroshima-style okonomiyaki — beautiful Seto Inland Sea islands like Miyajima with its floating torii gate, and a warm, welcoming local culture.
