Weather in Sapporo in July

A good month. July is a solid month to be in Sapporo. Highs average 25 °C, lows 16.4 °C, and rain falls on 12 days — nothing in the month is working against you.

July ranks 2 of 12 in Sapporo. Only June scores clearly higher, and the difference is small enough to be settled by price rather than weather.

Rain on 12 days, 4 of them heavy. Enough to need a plan B, not enough to need a plan around it. Nothing specialised needed — this is the month you pack for the trip rather than for the weather.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest July day reached 32.4 °C and the coldest night fell to 9.2 °C, and the wettest single day dropped 60 mm — roughly 50% of the month's rain in one day.

July is statistically steady but not small: the year-to-year variation is modest in relative terms, yet the wettest July on record still delivered 237 mm against 54 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 121 mm average is a reasonable planning figure, not a promise.

Wind is light at 3.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity at 86% is the real story though — it is the number that decides how the day feels, not the 25 °C.

How July sits in the year

Temperatures hold steady either side: 21.4 °C in June, 25 here, 25.9 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Sapporo's year: 15.1 hours of daylight, losing 0.7 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

Sea temperature

The sea sits at about 17 °C in July — cold — a quick dip rather than a swim, and a wetsuit if you are in for longer. This is the warmest the water gets all year.

How busy it gets

Peak season. Expect the highest prices of the year and to be booking well ahead.

Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.

July in Sapporo versus nearby

If Sapporo is one option among several, the nearby comparison is worth making. Sendai is the weaker option in July — 3.7 °C warmer, 6 days more rain. Niigata is the weaker option in July — within a degree on temperature, 5 days more rain.

So: July is effectively as good as it gets here — 6 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
