The short answer: the best time to visit Metz for weather is June to September, and the best single window is late June to early September, when the Constellations de Metz festival lights up the city free of charge and temperatures sit between 20°C and 24°C (68°F to 75°F). December earns a second recommendation for the Christmas market, one of the largest in eastern France. This guide breaks the year into specific windows for weather, events, low prices and low crowds, and it pairs with our Metz city guide.
Best Time to Visit Metz for Good Weather: June to September
June through September delivers the warmest, sunniest conditions. July peaks at 24°C (75°F) highs with 8 hours of sunshine a day, and August holds at 23°C (73°F). Rain stays moderate at 64 to 73 mm a month, falling as short showers rather than all-day grey. May and early June are cooler at 18°C to 21°C (64°F to 70°F) but less crowded and cheaper, so they are the practical pick if you want warm days without peak-season hotel rates. See the exact figures in the Metz weather by month breakdown.
Best Time to Visit Metz for Festivals and Events
Target the last week of June to the first week of September for the free Constellations de Metz, with video mapping on the cathedral every Thursday to Saturday night. The Fêtes de la Mirabelle over the last two weekends of August celebrates the local mirabelle plum with a market, concerts and fireworks on 29 August. From late November to late December the Christmas market fills Place Saint-Louis and Place d’Armes with over 100 chalets. Full dates are in the Metz events and festivals guide.
Best Time to Visit Metz for Lower Prices: January to March
January to March is the cheapest period to sleep in Metz. Chain hotels near the station drop well below summer rates, and you will often find a 3-star room for 55 to 70 EUR a night. The trade-off is cold, grey weather: January averages 3°C (37°F) with a single hour of daily sun. If you are visiting family or on business, this is when your euro goes furthest. Book 4 to 6 weeks ahead for the best weekend rates, and check the where to stay in Metz guide for hotel areas.
Best Time to Visit Metz for Fewer Crowds: April, May and October
April, May and October offer the best balance of mild weather and thin crowds. May reaches 18°C (64°F) and the tour groups have not yet arrived, so the cathedral and Centre Pompidou-Metz are quiet on weekday mornings. October runs 15°C (59°F) with autumn colour along the Moselle and short queues everywhere. Avoid August weekends, when the Constellations festival and the Mirabelle fair draw large regional crowds. Use the Metz neighborhoods guide to pick a quieter base.
