Hiroshima's Climate

Hiroshima sits on the Seto Inland Sea in southwestern Honshu, Japan, and has a humid subtropical climate with four distinct seasons. Summers (June–September) are hot and sticky, with daytime highs usually 30–34°C, and include the tsuyu rainy season around June and July, when steady rain lingers for weeks. Autumn (September–November) is cool and dry with lovely red foliage, while winters (December–February) are milder than much of Japan and rarely see heavy snow, sheltered by the inland sea. Typhoons can brush the region in August and September.
