Mount Fuji Weather in July

 Season: Summer
 What is the weather like in Mount Fuji in July?
Mount Fuji in July is characterized by hot weather and rainy season, but there is no heat. Although it’s cold on the mountain top, the temperature is above freezing point generally, so climbing season begins from the early month.

Temperature

Generally speaking, temperatures around the foothills are not very high, with average temperatures ranging from a low of 16 degrees Celsius (60.8 degrees Fahrenheit) to a high of 27℃ (80.6℉). There may be several days with the maximum temperature over 30℃ (86℉), but it scarcely exceeds 33℃ (91.4℉). Continuous intense rainfall may cause the maximum temperature to drop to around 18℃ (64.4℉), but this is just a rare case. In the early mornings and evenings, temperatures are comfortably cool, with lows staying no less than 14℃ (57.2℉) and occasionally rising above 21℃ (69.8℉).

Although in summer, the temperature on the mountainside is much lower than that of the foothills, with an average temperature of around 13℃ (55.4℉); the temperature on the top of the mountain averages from 3-8℃ (37.4-46.4℉), so there is no snow cover over the month.

July: Rainy Season with High Precipitation & Humidity

July is known as the month with substantial rain: the average monthly precipitation is 262mm and there are approximately 21 rainy days, most of which features light rain, accompanied by several moderate rainfalls; in some years, the rainstorm could occur for a few times. However, don’t be overwhelmed with the statistics, since light rain won’t cause too much trouble, and intense rain usually comes all of a sudden, stops after a while, and finally rewards you with a clear sky.

In the higher elevations, the weather condition is not stable, with thundershowers easy to happen. 

The climate this month is very humid, with the average humidity as high as 81% at the foot of the mountain and 79% at the top.

Daylight Hours & Sunshine Hours

Sunrise time (1st – 31st): 04: 34 – 04: 53
Sunset time (1st – 31st): 19: 05 – 18: 51

The daylight duration at the beginning of July is about 14.5 hours, and then gradually shortens to about 14 hours at the end of the month. Broadly speaking, the days are very long, so if you encounter a shower, you still have adequate time for outdoor activities. Getting up early to watch the sunrise may not be realistic, but watching the sunset on the top of Mount Fuji at places such as the shores of the Lake Kawaguchi at a clear moment is a pleasure.

Statistics show that the daily sunshine duration is about 8 hours, but the number of sunny days in the whole month is extremely rare, 4 days or so.

Is It Worth Visiting Mount Fuji in July?

Yes! The climbing season begins from early July when you can climb to the top of Mount Fuji if you’ve got the plan.

Besides, July is a good season to enjoy the beautiful natural scenery, especially during the time from early July to mid-July when there are large areas of blooming purple lavender in the Lake Kawaguchi. 

Packing Guide for Mount Fuji Trip in July

 Clothing
Summer shirts, summer pants, shorts, and dresses are suitable for staying under the mountain. But if you are going to climb the mountain, better wear quick-drying inner layers and warm, windproof mountaineering jackets and trousers.

 Shoes
Casual sneakers, canvas shoes, and sandals will do in flat areas. Climbing shoes are needed for climbers because the road conditions are very bad.

 Others

Umbrellas and raincoats are essential during the rainy season. Sun protection gear such as sun-protective clothing, sunscreen, sunglasses, and a sun hat are also crucial, as the average UV index this month reaches 6, and the UV rays are even stronger on the mountain. Hikers should bring extra items like a mask, trekking poles, a headlamp, a water bottle, and some instant food; most importantly, those prone to altitude sickness are advised to bring one or two bottles of oxygen.

Delightful Events You May Like in Mount Fuji in July

 In early to mid-July, the Lake Kawaguchi Herb Festival is held in the main venues of the Oishi Park and Yagizaki Park where you can enjoy diversified local specialties and buy handicrafts while admiring the beautiful purple lavender.

 Every year on the first Saturday of July, a grand fireworks display is held at Oike Park in Kawaguchiko, marking the opening of Mount Fuji. The reflection of the colorful fireworks blooming in the night sky on the lake will surely give you a visual surprise.

Travel Tips

 If you’re preparing a July hike in 2026, it’s best to make reservations in advance, as there are restrictions on the number of climbers during the climbing season, especially for the most popular Yoshida Trail. Peak climbing season begins at the end of July, and you might need to book a month earlier. It’s important to note that trail entrances close between 4:00 PM and 3:00 AM daily during peak season, so plan your ascent time accordingly.

 If you want to take nice photos of the Mount Fuji in distance, it’s suggested that you come in early morning or at dusk when the visibility is higher.
