Traveller notes on Maastricht in September
Notes from nearby Luxembourg (127 km away)
Maastricht doesn't have its own notes for September yet — these are about Luxembourg, close enough to share the season.
September in Luxembourg is a coin-toss between seasons — the forum's own phrasing is that some years it is still summer and some it is already autumn — but the consensus favours it over October, when the odds of rain and fog climb. Days sit near 19°C, cooling to about 10 at night. It is too early for real autumn colour: locals put the good stretch from around mid-September through early November, with the lazy foggy mornings and colour in midday sun arriving later than the calendar suggests. Regulars pair the trip with the Belgian Ardennes and the German Eifel.
