Weather in Hokkaido in September (overview)
Even in Hokkaido, the maximum daytime temperature will often exceed 20 degrees during this time. Furano and other sightseeing spots, still beautiful flowers are waiting for you. I think that you can enjoy a pleasant journey.
However, please note that in September, typhoons or temperate cyclones may strike. When heavy rain or wind blows, airplanes and trains will stop. In order not to get caught in such a trouble, please get the latest weather forecast from the net or TV. The umbrella is an essential part.
In Hokkaido, the difference of the temperature in the day is intense throughout the year. It will be chilled a lot in September in the morning and evening. The minimum temperature of the day may be less than 10 degrees Celsius. It's pretty cold, so let's prepare clothes such as jumpers.
If you are planning to visit the highlands such as Daisetsuzan this time, winter clothes are necessary. In Daisetsuzan, winter comes at the summit in mid September. In late September, snow may accumulate to the knee height at the summit of the mountain.
