Sapporo in December Snow settles in. The Christmas market in Odori Park runs until December 25 and the illumination continues, making for good evening walks. Snowfall is heavy, so sort out footwear first.
Sapporo in December was a deep-winter month, with highs of 2°C and lows of −4°C. Precipitation was a regular part of the month, showing up on 20 days on average. At 2°C by day, a good share of the wet days were snow days, so the rain-day count includes fresh snow and the totals count it as melted water. Averages hide a lot here: one year saw 11, another 29.
The month opened with 9.3 hours of daylight and closed with 9.1. Dusk came early. 27 nights a month dropped below freezing on average. Gloves earned their place for early starts. Cold snaps happened: the record low for December was −14.5°C, set in 2020.

With precipitation every other day or more, waterproof outer layers and boots were a necessity, not extra luggage.
