Weather in Groningen in July

A good month. July is a solid month to be in Groningen. You should expect rain on 16 days of the month, which is more days wet than dry.

July ranks 3 of 12 in Groningen. Only June scores clearly higher, and the difference is small enough to be settled by price rather than weather.

This is persistent light rain rather than storms: 16 wet days but only 1 heavy ones. It rarely cancels anything outright, and it rarely fully clears either. A jacket beats an umbrella. 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 35.3 °C and the coldest night fell to 8.9 °C, and the wettest single day dropped 25 mm — roughly 32% 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 138 mm against 10 mm in the driest. In a month this wet, even a tame spread is a lot of rain in absolute terms — the 79 mm average is a reasonable planning figure, not a promise.

Wind is light at 11.8 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 78%, high enough to notice on the warm days without dominating them.

How July sits in the year

Temperatures hold steady either side: 20.1 °C in June, 22.1 here, 22 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Groningen's year: 16.5 hours of daylight, losing 1.1 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 Groningen versus nearby

If Groningen is one option among several, the nearby comparison is worth making. Bielefeld is close enough to be a coin toss — within a degree on temperature, 1 day less rain. Rotterdam is close enough to be a coin toss — within a degree on temperature, 2 days less rain.

So: July is effectively as good as it gets here — 5 points behind June, which is inside the margin where the weather stops being the deciding factor and price starts being it.
