Tokyo Weather in September: September ushers in fall, which means the gradual decline of humidity and heat, but this month is also the darkest and wettest, with an average of 209mm of rainfall. Temperatures don’t start dropping significantly until late September. Though the average high temperature is 26°C., it’s not uncommon for temperatures to rise as high as 33 °C during the first few weeks of the month. (Average Max Temperature: 26°C. Average Precipitation: 181mm.)

• Best Time for Sightseeing:, The weather is pleasant, with frequent sunshine and little rain. In November, there is a slight chill in the air, but the weather is often idyllic, and you’ll enjoy the peak of autumn foliage while exploring the city. There is little rainfall, skies are clear, and temperatures are mild. July and August are typically the hottest and most humid times of year, and can be uncomfortable for sightseeing if you’re averse to humidity. Crowds are also at their peak, which means you’ll be bumping elbows with a lot of other sweaty tourists. No matter what time of year you go, major sights like Sensoji temple are best visited on a weekday morning, or later in the evening – Sensoji is typically deserted after dark, with all shops in Nakamise closed.
• Best Time to Visit Tokyo Disney Resort: The best time of year to visit Tokyo Disney Resort to avoid the biggest crowds and enjoy the best weather, is in the spring, before or after Golden Week which takes place at the end of April and beginning of May, but before the rainy season begins in June. The next best time is mid-November through early December. If you just want to ride as many attractions as possible and don’t mind the rain, visiting in June or October is ideal – on any very rainy day the crowds are minimal and most rides have shorter wait times. Tokyo Disney Sea (on the same property as Tokyo Disney and connected by monorail) will always have shorter lines than the Disney Resort.
• Best Time to Visit Tsukiji Fish Market: The Tsukiji Fish Market is the largest wholesale fish market in the world. It’s one of the most exciting places to be, whether you arrive in the wee hours of the morning for the tuna auctions, or later in the morning to enjoy a sushi breakfast. As the market is slated to move to the nearby Toyosu district early in November 2016, you’ll need to visit before then to experience its rich history and character.
