Weather in Colmar in July

A good month. July is a solid month to be in Colmar. Highs average 26.4 °C, lows 15 °C, and rain falls on 14 days — nothing in the month is working against you.

July ranks 3 of 12 in Colmar. Only September 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: 14 wet days but only 2 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

Averages flatten a month, and this one hides a few things: 6 days top 30 °C — hot spells arrive, but they break. Across the twenty years measured, the hottest July day reached 38.1 °C and the coldest night fell to 8.4 °C, and the wettest single day dropped 41 mm — roughly 48% of the month's rain in one day.

July is moderately variable: 33 mm in the driest year against 221 mm in the wettest, around an average of 85 mm. Roughly two Julys in three land near that average, and the third does something else entirely.

Wind is light at 5.7 km/h, so the temperature on the page is close to the temperature on your skin, and humidity is unremarkable at 70%.

How July sits in the year

Temperatures hold steady either side: 24.5 °C in June, 26.4 here, 26 in August. Nothing about the timing within the month matters much.

Daylight in July

July is at or near the longest days of Colmar's year: 15.7 hours of daylight, losing 0.9 hours across the month. Evenings are the real gain — dinner outdoors still happens in full light.

An inland climate

With no coast nearby, the year swings a fair way — 28.1 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.

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 Colmar versus nearby

If Colmar is one option among several, the nearby comparison is worth making. Luzern is the weaker option in July — 2.1 °C cooler, 4 days more rain. Stuttgart is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

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