Metz sits in northeastern France, roughly 55 km (34 miles) from the German border and 60 km (37 miles) from Luxembourg, in the Moselle river valley. The city has a temperate oceanic climate with a clear continental edge: winters run cold and grey, summers stay mild to warm, and rain falls fairly evenly all year with no true dry season. Annual rainfall averages around 750 mm (30 in), spread over about 150 rainy days. The warmest month is July at a 20°C (68°F) daily average and the coldest is January at 3°C (37°F). For the full city picture, see our Metz city guide and use the figures below to pack for the season you are actually visiting.

January is the coldest month, with daytime highs around 4°C (39°F) and overnight lows of -1°C (30°F). Expect about 73 mm of rain across 18 wet days and only 1 hour of sunshine per day, so bring a warm waterproof coat and expect short, grey days. February stays almost as cold: highs of 6°C (43°F) and lows of -1°C (30°F), 61 mm of rain over 14 days, and 3 hours of sun. Snow falls occasionally, but the Moselle valley rarely holds heavy snow for long. If you visit in these months, plan mostly indoor things to do in Metz around the museums and the cathedral.

April brings highs of 14°C (57°F), lows of 4°C (39°F), 53 mm of rain over 15 days and 5 hours of daily sunshine. By late April the café terraces on Place Saint-Louis reopen and the Esplanade gardens turn green, but mornings and evenings still need a jacket if you are walking the Metz neighborhoods on foot.
