The Wettest Month of the Year

Monthly Humidity: around 84%

July ranks as the rainiest month over the year, averaging 320 mm (12.6 in) monthly precipitation for 18 rainy days. As the rainy season lingers till the middle to late month, Shizuoka frequently experiences moderate showers with occasional heavy rain. Rainfall mostly lasts no more than half a day, but sometimes it occurs several times within a day.

Because of a lot of rainfall in early and mid-July, humidity is high, leading to higher apparent temperature. Besides, the high humidity, together with high temperature, often brings people sultry feelings. As the rainy season ends, sunny days become common, and the dampness subsides day by day.

Best Things to Do in Shizuoka in July

See Fireworks Shows

Fireworks over the Sea

In summer, Atami Fireworks Festival with 5,000 fireworks is worth a visit. According to its schedule in 2026, there will be two fireworks shows from 20:15 to 20:40 in middle and late July respectively.

Tips:
1. In case of rain, the date of fireworks displays may be adjusted. So, if you don’t want to miss such splendid events, keep a close eye on the latest notices.
2. Due to big streams of visitors, you’d better come to the site at least half an hour earlier to secure a good spot.

Climb Mount Fuji

Though you will not see the snow cap of Mount Fuji, you have a chance to explore its appeal up close from different routes. The official climbing season lasts two months, from early July to early September.

Tips:
1. As the altitude increases, the temperature becomes lower and lower. So, a 3-in-1 jacket with a removable down liner is recommended.
2. Monitor the weather forecast prior to your hike. If heavy rain and strong winds are forecasted that day, it’s better to cancel this activity for safety concerns. However, if there will be light rain and no winds, it’s still possible to climb. But besides specialized mountaineering gear like headlamps and trekking poles, your clothes, gloves and shoes should be waterproof.
3. If your travel plan includes Mt. Fuji World Heritage Centre, note that its opening hours are extended from 9:00 - 17:00 to 9:00 - 18:00 in July and August.
