Tokyo Weather in August

Season: summer; typhoon season; Mount Fuji climbing season

August is the hottest period of the year in Tokyo. About half of the month sees high temperatures above 35 degrees Celsius (95 degrees Fahrenheit). Frequent showers occur, some of which are brought by active typhoons. Therefore, air humidity remains at a high level, increasing the stuffiness.

Temperature: High value exceeding 35℃ (95℉)

Tokyo weather in August is torrid, day or night.

The temperature is usually above 30℃ (86℉) during the daytime. High humidity strengthens oppressive feelings, and perceived temperatures above 35℃ (95℉) are common, on about 15 - 20 days on average. Walking outside, it feels like you are in a sauna. It’s easy to sweat heavily, and your hairspray can only work for around 15 minutes. Those who are not heat-resistant feel uncomfortable when staying outdoors for a long time. Occasionally, the wind blows, but you don’t feel noticeably cooler.

Even at night, things don’t go well. The low temperature is no less than 24℃ (75.2℉), and you may have trouble falling asleep without air conditioning.

Frequent thundershowers

Although the number of rainy days is not that large, the total precipitation is considerable. The reason lies in that rainstorm or thundershower is the main form. They come and go quickly, but bring a lot of rainwater and may visit more than once in a day, mainly during the afternoon to evening. Continuous light rain rarely takes place. Therefore, if encountering rainfall during outings, it’s feasible to find temporary shelter and wait for the rain to stop.

Peak month of typhoon

Typhoons are most active in August throughout the year in Tokyo. Some turn away when approaching Tokyo, while 1 - 3 directly hit the city each year on average. They range from tropical storms to super typhoons, bringing rainstorms and strong winds at the same time. The impact of each landing usually lasts for 2 - 5 days, during which period you may face the outage of flights and the Shinkansen. Attractions also close temporarily for security reasons. When the typhoon leaves, the weather becomes clearly sunny.

For visitors, it’s important to check the weather forecast again several days before departure. You should better avoid typhoon days. If it’s not a severe one and you have to go, leave free days for possible plan delay brought by typhoons. If possible, make a plan B just in case.

Long sunshine hours and daytime

Sunny or cloudy climate dominates August in Tokyo. Even if on days with rainfall, the weather alternates quickly between sunny and rainy. Therefore, it receives rich sunshine on the whole, about 6 hours each day on average. However, strong sunlight is worth attention. The UV index can be as high as 10.

The daytime averages at 13.5 hours from sunrise at 4:49 – 5:12 to sunset at 18:10 – 18:45, serving as a precondition for a thorough Tokyo trip. If it’s not enough for you, make use of the wonderful nighttime.

Is it ok to visit Tokyo in August?

August is a not-so-good time to travel to Tokyo, actually. The weather is broiling with downpour sometimes and strong sunshine other times, requiring you a lot of energy for outdoor visiting, and possible typhoons can also disturb your planned travel. In addition, the summer holiday in Japan incurs a travel high season in Tokyo, when tourists surge, and prices soar. You have to take longer times visiting top attractions like Senso-ji Temple, Nakamise-dori Street, Meiji Jingu Shrine, and Tokyo Disneyland, and spend more money on transportation, accommodation, and catering than in the low season.

But on the other hand, various festivals are celebrated this month, offering great opportunities to experience traditional Japanese customs. Wonderful night activities like fireworks shows can also prolong your travel span. In addition, Mount Fuji is open to the public in the month, which is good news for hiking enthusiasts.
