Weather Forecast for Hiroshima, Japan: August 10-12, 2025

As we look ahead to the weather in Hiroshima over the next few days, residents and visitors should brace themselves for a series of rain showers that will predominately define the upcoming conditions. The forecast indicates notable precipitation and cool temperatures, characteristic of the late summer weather pattern in this vibrant city.

Saturday, August 10, 2025

Expect a cloudy day with the potential for substantial rain starting early in the morning. The maximum temperature is projected to be around 25°C (77°F), with a minimum of 24°C (75°F). Throughout the day, the humidity will hover near 99%, leading to a high likelihood of moderate to heavy rain—up to 3.0mm expected within just a few hours. Winds from the south-southwest will bring a gentle breeze at approximately 22 km/h (14 mph), maintaining a consistent feel of warmth despite the precipitation. This might make you feel hotter than the actual temperature, with a heat index rising to 28°C (83°F).

Visibility could be reduced to around 5 miles during the heaviest rain showers, making travel potentially challenging. Outdoor activities are best postponed if possible; however, the rich cultural offerings of the city might still be enjoyed during light breaks in the rain.
