Temperature: Cooler and Cooler

In October, the temperature in Hirosaki is generally declining.

In late September, the climate is obviously much cooler, as the temperature fluctuates between 10-15℃ (50-59℉) during the day. After an intense rainfall, though it rarely happens, the maximum temperature can drop to below 10℃. In early mornings and late afternoons when the temperature is as low as 4-8℃ (39-46℉), you would feel like it’s already in cold early winter.

Precipitation: Mainly Showers

To be exact, light showers are commonly seen over the month, which means that you may encounter a short period of light rainfall, and then see sunlight penetrating through the clouds after a while.

With the mean relative humidity of 80%, you may feel cozy during the day, but a bit clammy during early and late hours.
