Traveller notes on Strasbourg in December
Notes from nearby Colmar (63 km away)
Strasbourg doesn't have its own notes for December yet — these are about Colmar, close enough to share the season.
Colmar-forum threads on December weather describe the Alsace region as cold and genuinely windy this time of year, layers doing more work than any single heavy coat, though actual snow in town is called uncommon in early-to-mid December - a light dusting shows up roughly one year in three, with a better chance of real snow up on the surrounding Vosges mountain tops than down in the old town streets. The famous Christmas markets are the whole draw regardless of the chill, running late November through year's end, and regulars are specific about timing: weekday mornings and Sunday evenings in late November or early December bring thinner crowds than weekends or Christmas week itself. The half-timbered old town is called especially magical lit up for the holidays, cold enough for mulled wine breaks but not so cold it ruins the evening. The record: 6.8C days feeling like 4C, 1C nights, 82mm across 12.8 days, 7.7cm of fresh snowfall, 87 percent humidity and just 4 hours of sun.
Other months in Strasbourg
Regulars are specific this technically counts as the wettest month of the year here, an umbrella genuinely worth carrying, though rain tends to arrive as afternoon thunderstorms that clear quickly rather than a settled grey day. Our row backs that mild, genuinely wet read, 21.2C over 9.9C nights, with 77.5mm of rain across 10.5 days and humidity at 70 percent. Regulars are consistent this remains genuinely excellent walking weather overall, storks visibly migrating back to the region as a real seasonal marker, with noticeably fewer crowds and shorter museum lines than deep summer. This counts among the better months to pair with Alsace day trips before the peak-season rush arrives. The record: 10.9 hours of sun, a 13.4 kph wind and AQI 46.
August here pulls in two directions and regulars name both. The school holidays fill the old town and the Alsace villages; the European Parliament closes for the month, which takes its business travellers out and brings hotel rates down rather than up. That combination is unusual enough to be worth planning around. The weather is warm and unpromised - our row gives 27.3C reading as 28C over 15.1C nights, with 60.3mm of rain across 8.7 days, and the board's own caution is that summer here can still turn bad. Some prefer late August into September for the softer light. The record: humidity 68 percent, 10.9 hours of sun and AQI 44.
Regulars put early June here in the low to mid twenties, tell you to bring an umbrella anyway, and make the honest promise rather than the confident one: a week in June will almost certainly contain some good days. Our 26.2C over 14.4C sits at the top of their range, with 83.6mm across 10.2 days. What June has over July and August is not weather but quiet - those two are drier and also full, because the French school holidays and the tourist season land together. Summers here are warm and humid and the board has seen both a week of heavy rain and an outright heatwave in these months. Daylight runs to 16.1 hours. The record: humidity 69 percent, 12.3 hours of sun and AQI 51.
July in Strasbourg is warm and humid, and regulars are candid that nobody can tell you what a given day will do more than about two days ahead. Their mid-70s Fahrenheit is our row's 27.4C reading as 28C, and the rain they warn about shows up as 57.4mm across 9 precipitation days - not a wet month by Alsace standards, but enough that layers and a rain covering are the standing packing advice. July and August they call the safer half of the year for dry weather, with the caveat attached. The Rhine-plain humidity is what makes the same temperature feel heavier here than in Paris. The record: 14.9C nights, humidity 65 percent, 12.3 hours of sun and a 15.7-hour day.
