Warming-up Temperatures

Sapporo’s weather in May is generally warm, with the average temperature ranging from 9-19°C (48-66°F). A long-sleeve shirt with a trench coat is usually enough for your daily outfit. However, the weather can still be unpredictable – some days can be bright and sunny, with highs soaring up to 27 degrees Celsius (81 degree Fahrenheit), while others are rainy and cool, with the perceived highest temperature dropping to around 11 degrees Celsius (52 degrees Fahrenheit). Given these fluctuations, it's a good idea to check the weather forecast before your visit and dress accordingly.

Another point to keep in mind is the large difference between daytime and nighttime temperatures. On sunny days, you can feel it being like over 20°C (68°F) at midday, but in early mornings and late evenings, the temperature may dip to just 8-9°C (46-48°F). If you plan to take the Sapporo Mt. Moiwa Ropeway for night views, expect even colder climate, as the temperature can fall to 6-7°C(43-45°F), or even lower if it's raining. Therefore, bringing a scarf or extra layer is highly recommended for evening outings.

Rainfall and Humidity

May is the driest month of the year in Sapporo, with an average monthly precipitation of just 56 mm and 8 rainy days. Most of the rain comes in the form of light showers that usually won’t last for too long, though there are two or three days when it rains all day long. Thus, it’s always a good idea to plan your outdoor activities based on the weather forecast.

It’s worth noting that light rain often comes with fog, offering the city a slightly humid but peaceful atmosphere – perfect for a relaxed stroll in the park or a light hike in the surrounding hills. But low visibility of air may discourage to visit the JR Tower Observation Deck T38. The average humidity for May is about 63%, which is generally comfortable for travel.

Sunshine Hours & Daytime Hours

Sapporo Clock Tower

Sunshine Hours: about 6 hours
Sunrise: 3:58-4:28
Sunset: 18:35-19:06
Daytime Hours: 14 hours 7 minutes - 15 hours 8 minutes

Sapporo in May enjoys really long daytime hours, allowing visitors to explore the city in a more relaxed way. However, keep in mind that longer daylight doesn’t mean attractions stay open later. For example, the opening hours for iconic Sapporo Clock Tower are still from 8:45-17:10. So you still need to prioritize these key attractions in the day.

Another important thing you need to note is sunrise hours also become longer, and the UV Index can reach as high as 6. Don’t forget to apply sunscreen, wear sunglasses, or bring a hat to protect yourself from sun exposure, especially during midday outdoor activities.

Is May a good time to visit Sapporo?

Yes, May is a good time to visit Sapporo.

Overall, Sapporo’s climate in May is mild with less rain, perfect for outdoor adventures. Plus, as the temperature rises, the city becomes greener and more vibrant, creating a fresh and pleasant environment.

May is also a good time to appreciate seasonal flowers. Early May is the peak season for sakura blossom, which may be the last chance to catch it in 2026 in Sapporo. Shortly after, the city welcomes lilacs and tulips, adding more colors to Sapporo’s parks and streets.

While early May coincides with Japan’s major holiday period – Golden Week, Sapporo tends to be much less crowded than popular cities like Tokyo or Osaka, making it more comfortable for visitors. Flights and hotel prices may spike during the holiday, though not as drastically as in peak winter season, so booking early is recommended.
