Météo à Coimbra en septembre

September in Nazare is pleasant and the wrong month for what the town is famous for. Regulars put the giant waves between October and February, with December to February the reliable window and January capable of 30 metres and more; September gives you no great chance of them. What it does give is warm, mostly sunny weather at 19 to 22C - our row says 24.6C over 16C - with the beach itself cool enough that some visitors complain. The Atlantic here stays at 19.3C. So: come now for the town and the cliff at O Sitio, come in winter for the spectacle. The record: 4.6 precipitation days carrying 32.1mm, a 20.7 kph wind and 10.7 hours of sun.

Forum posters describe November in Coimbra as genuinely variable - one visitor's four-day stay brought rain almost every day, while posters more broadly describe a typical visit needing only a shower or two in the morning, with some years bringing lots of warm weather punctuated by the odd rainy day and chilly evenings. Posters consistently recommend packing a raincoat and umbrella, and good walking shoes given how slippery Coimbra's cobbled streets get when wet. Posters are direct that November counts among Portugal's more difficult, rain-prone months overall, but also one of the least touristic alongside January, meaning shorter lines and quieter sightseeing at Coimbra's university and historic sites. Posters generally rate November as genuinely rain-prone but rewarding for a Coimbra visit, with low crowds a real upside of the wetter shoulder season.

Forum posters describe May in central Portugal as edging toward summer, with typical daytime temperatures in the 20-23C range cooling to around 13C overnight. Opinions on packing split a little: some posters say shorts and sandals are enough given how close the weather is to summer, while others recommend bringing a light jacket since rain remains a real possibility this early in the season. For Coimbra specifically - a university town known for its historic architecture along the Mondego river - posters describe it as a pleasant, walkable size for a day or two, with a genuinely hot day always possible even in May, per one visitor who ducked into a shopping mall's food court specifically to escape unexpected heat.
