מזג האוויר בקוימברה במרץ

Forum posters call March a genuinely lovely month to visit despite the rain risk - days are getting longer, spring blooms are starting, and a great sunny weekend is entirely possible alongside the more typical grey, foggy stretches. Porto is consistently described as rainier and foggier than Lisbon and the south, so the odds of a wet day are real, but posters are clear that a full week of solid rain is uncommon anywhere in Portugal, even in the north. Nearly everything touristy stays open year-round except the longer river cruises, so the advice is simply to have an indoor plan B rather than avoid the month.

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.
