Shizuoka Weather in July

Season: Summer
What’s the weather of Shizuoka like in July: hot; the rainiest month in a year

Hot

Average Temperature: 23-30℃ (73-86℉)

In midsummer, July brings a notable sense of heat in Shizuoka. There are more than 20 days with daily maximum temperatures of above 30 degrees Celsius (86 degrees Fahrenheit), and in some warmer years, ones during sunny periods may soar to 36-39℃ (97-102℉). Rainy days tend to bring a decrease in temperature, but the increased humidity after the rain results in higher apparent temperature. In contrast, sunless conditions make your outdoor exploration more comfortable, because the temperature drops to 22-27℃ (72-81℉).

Favorable Period to Experience Water Activities

In July, seawater temperature in Shizuoka ranges from 23-27℃ (73-81℉), warm enough to experience water sports. Thanks to the sea breeze, beach areas become ideal escapes from summer heat for domestic and foreign tourists. The majority of beach resorts officially open from mid-July to late August, offering comprehensive supporting facilities and professional lifeguards. 

Here are excellent destinations for you to choose from: Shirahama Ohama Beach, well-known for its white fine beach and crystal-clear water; Sotoura Beach with calm waves, making it a perfect place for children; Tatadohama Beach, one of most famous surfing locations in Shizuoka.

The Wettest Month of the Year

Monthly Humidity: around 84%

As the rainy season lingers in the middle of the month, July ranks as the rainiest month over the year, averaging 320 mm (12.6 in) precipitation. During 18 rainy days, light showers are most frequent, while heavy and moderate rain have a comfortable mix. Due to the changeable climate of Shizuoka in July, rainfall mostly lasts no more than half a day, but sometimes it occurs twice within a day. The weather statistics in 2024 and 2025 indicate that early mornings were more prone to rain. 

With a combination of high temperatures and humid air, you often feel sultry and sticky outdoors in this month. 

Daylight Hours & Sunshine Hours

Sunrise Time: 04:38 - 04:58
Sunset Time: 18:52 - 19:07
Daylight Hours: 14 hours 28 minutes - 13 hours 54 minutes
Daily Sunshine Hours: approximately 5 hours per day

Though daylength begins to shorten, it is still long enough for your daily outings. 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 only in July and August. 

After mid-July, sunny days and daily sunshine hours are both increasing. Plus, sunlight is very intense with the UV index hovering around 10, so sun protection is required.

Things Yon Need to Pack for Shizuoka Trip in July

 Females: Breathable clothes are always your top choices in this time. It’s advisable to wear a slip dress, a chiffon long-sleeve layer and well-fitting sandals; this outfit is not only comfortable and fashionable, but also ensures you look photogenic in the shot.

 Males: Males tend to sweat more in summer, so the clothes are better to be quick-drying, like short-sleeved shirts or tank tops and shorts in a cotton or linen fabric. As for footwear, mesh sneakers or slip-ons are highly recommended.

 Accessories: 
1. Pack sun hats, sunglasses and sunblock. Reapply the sun cream every 2-3 hours, particularly when you stay by the sea for a long time. And parasols are enough to cope with rainy and sunny weather.
2. Swim gear includes swimsuits, beach towels and lightweight slippers.
3. To avoid heatstroke, regularly drink lots of cool liquids, or bring along a portable mini fan.
4. There are many mosquitoes, so mosquito repellent is needed.

Best Things to Do in Shizuoka in July

See Fireworks Festivals

In summer, Atami Fireworks Festival with 5,000 fireworks is worth a visit. According to its schedule in 2026, there are two performances from 20:15 to 20:40 in mid- and late July. The best viewing spots are Atami Sun Beach, as well as Sky Deck and Rainbow Deck of Atami Nagisacho Park. Another must-see show is 1.5-hour Fukuroi Enshu Fireworks Festival, held at the end of the month, when 25,000 fireworks light up the night sky, accompanied by rousing music. 

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

Climb Mount Fuji

Though you’re highly unlikely to see the snow-covered peak 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 is increasing, the temperature becomes lower and lower. So, a 3-in-1 jacket with a removable down liner is a must-have.
2. Monitor the weather forecast prior to your hike. If heavy rain and strong winds are expected that day, it’s better to cancel this activity for your safety. 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. 500 ml water is usually sufficient on rainy days, but you need more on sunny days.
