Typhoons and Strong Winds

In September, Kamakura experiences an average rainfall of 186mm over approximately 18 rainy days. You might wonder why the rainfall is still relatively high since the traditional rainy season is already over. This is because September is a peak season for typhoons. As a coastal city along the Pacific Ocean, Kamakura is prone to typhoons and is significantly affected. When typhoons land on Kamakura, expect heavy downpours accompanied with strong winds. Based on the previous data of September 2024, the wind speed is up to force 8 at their peak and over 70 km/h (44 mph). Therefore, it’s not suitable to visit Kamakura during these times.

The good news is that typhoon tracks are generally predictable, and forecasts tend to be quite accurate. Therefore, it's highly recommended to check the weather updates in advance and adjust your travel plans accordingly to avoid disruptions.

Humidity

Due to heavy rain in September, Kamakura’s average humidity level is 71%. In the first half of the month, high temperatures would intensify the uncomfortable and sticky feelings. As temperatures and rainfall ease, visitors would feel much drier, especially in the late month.
