Weather in Colmar in October

A good month. October is a solid month to be in Colmar. Highs average 17.1 °C, lows 7.1 °C, and rain falls on 12 days — nothing in the month is working against you.

October ranks 7 of 12 in Colmar: past the worst of the year but short of September, which is the month to book if the dates are open.

Rain on 12 days, 2 of them heavy. Enough to need a plan B, not enough to need a plan around it. Pack for 17.1 °C days and 7.1 °C nights; the spread matters more here than any single number.

What the averages hide

The averages here are honest — no hidden extremes worth planning around. Across the twenty years measured, the hottest October day reached 28.4 °C and the coldest night fell to -4.4 °C, and the wettest single day dropped 37 mm — roughly 47% of the month's rain in one day.

October is moderately variable: 11 mm in the driest year against 162 mm in the wettest, around an average of 78 mm. Roughly two Octobers in three land near that average, and the third does something else entirely.

Wind is light at 5.6 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 84%, high enough to notice on the warm days without dominating them.

How October sits in the year

The month is on the way down: 5 °C cooler than September, with November dropping another 6.6 °C. The first week and the last are not the same trip.

Daylight in October

10.9 hours of daylight, losing 1.7 hours across the month. That is between Colmar's extremes of 16 and 8.4 hours, so days are long enough not to constrain the plan.

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

Busy. Popular without being frantic; book the things you care about, improvise the rest.

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

October in Colmar versus nearby

If Colmar is one option among several, the nearby comparison is worth making. Luzern is close enough to be a coin toss — within a degree on temperature, 1 day more rain. Stuttgart is close enough to be a coin toss — within a degree on temperature, the same number of rain days.

So: October works, with September the better month by 12 points if the dates can move. If they cannot, nothing here should stop you booking.
