Tottori weather month by month
Tottori weather follows the pattern of the Sea of Japan coast: warm to hot summers, mild spring and autumn days, and a winter with cold temperatures and some snow. The figures below are official normals from the Japan Meteorological Agency for 1991 to 2020. They describe what a typical month looks like, not the forecast for your dates and not the weather measured in 2026. Check a forecast shortly before you travel.
The tables use two stations, one in Tottori city and one in Yonago. They suit the coast and the lowlands. They say nothing about the top of Mount Daisen, so for a hike read the Mount Daisen page and look up conditions for the mountain itself.
