Month-by-Month Guide
Climate conditions and crowd levels for each month of the year.
January feels like winter with intent: highs of 6°C (42°F) and overnight lows dipping to -1°C (30°F), with rainfall of around 104mm spread across the month. The city is grey and quiet, and the light doesn't last long. But the old town has a certain austere quality in winter that summer visitors never see.
February warms slightly, with daytime highs nudging toward 9°C (48°F), and as it happens, it's one of the drier months of the year at just 38mm of rainfall. Nights remain cold. You'll notice Luxembourg City starting to shake off its winter quietness toward the end of the month.
March sits in that ambiguous zone between seasons: highs reach 13°C (55°F) but overnight temperatures still drop to around 1°C (33°F), and 66mm of rainfall means you'll have some wet days. The first café terraces start appearing optimistically, often with outdoor heaters doing heavy work.
April brings a genuine easing of winter's grip, with highs at 15°C (59°F) and a relatively modest 56mm of rainfall. The Alzette valley greenery starts to come through properly, and Luxembourg City's parks become pleasant places to walk.
May is complex. Highs reach a comfortable 20°C (68°F) and the country looks its best in spring color, but 109mm of rainfall makes it the wettest month of the year. You'll likely have lovely days interrupted by heavy downpours. Pack accordingly and embrace the rhythm.
June tends to catch people off guard with how good it is. Luxembourg in June offers highs of 25°C (77°F), lows of 10°C (50°F), and just 46mm of rainfall, the driest month outside of February. The long evening light and warm temperatures make the old town appealing for evening walks.
July mirrors June's warmth with highs at 25°C (77°F) and lows of 11°C (51°F), but rainfall climbs back to 84mm, mostly in the form of afternoon storms. Mornings stay clear and warm. Watch the sky from early afternoon. Storms roll in fast.
August stays warm at 25°C (77°F) highs and 12°C (53°F) lows, with 81mm of rainfall following a similar pattern to July. It's peak tourist season in Luxembourg, which in absolute terms is still modest compared to major European capitals. Queues remain short.
September opens Luxembourg's most underrated stretch. Highs drop to 23°C (73°F) and lows to 10°C (50°F), rainfall is 79mm, and the summer crowds start to thin while the temperatures remain comfortable. The Moselle wine region is harvesting. That adds appeal.
October demands respect. Highs fall to 17°C (62°F) and lows to 6°C (42°F), and at 104mm this is one of the wettest months. The Mullerthal forest turns copper and gold. On dry days the hiking is exceptional. Rain can last days. Pack layers.
November strips things back. Highs of 10°C (50°F) and lows of 3°C (37°F) with 89mm of rainfall make it a properly autumnal month. Luxembourg City's covered markets and indoor museums become central to any visit.
December brings highs of 6°C (42°F) and lows of 1°C (33°F), with 64mm of rainfall that sometimes arrives as sleet or light snow. The Christmas market on Place Guillaume II draws visitors through December. That gives the month life.
