Packing for Sapporo in January means dressing for -3°C days and -9°C evenings.

💡

Local tip: Temple and religious site visits require covered shoulders and knees in most of Sapporo's heritage areas. A lightweight scarf or sarong weighs almost nothing and solves the problem instantly.

Why is Sapporo cool in January?

In January, Sapporo feels the full influence of the continental polar air mass, which dominates mid-latitude interiors during winter. Cold, dry air from the north suppresses temperatures to -3°C during the day, dropping further to -9°C at night when radiative cooling is greatest. Precipitation tends to be low, as the cold air holds little moisture. Climate data: Open-Meteo ERA5 (1991–2020).

Sunshine Hours

The average number of hours per day with direct sunlight. Calculated from satellite measurements. Days with more than 7 hours of sunshine are ideal for outdoor activities. Under 3 hours means overcast conditions dominate.

UV Index

A scale from 0-11+ measuring ultraviolet radiation intensity. UV 0-2: Minimal risk. UV 3-5: Moderate -- wear sunscreen. UV 6-7: High -- hat and SPF 30+ essential. UV 8-10: Very High -- limit midday exposure. UV 11+: Extreme -- seek shade between 10am-4pm.

Rain Days

A rain day is counted when precipitation exceeds 0.1mm. This threshold captures even light drizzle. Unlike total rainfall in mm, rain days tells you how often you might need an umbrella, which is useful for planning outdoor activities.

Humidity

Relative humidity as a percentage. Below 40%: Dry -- skin and throat may feel parched. 40-60%: Comfortable -- ideal for most people. 60-80%: Sticky -- light, breathable fabrics recommended. Above 80%: Muggy -- heat feels more intense; quick-dry clothing is essential.
