If you’re wondering what’s the best month to go to Portugal, the good news is that one of Portugal’s perks is its year-round sunshine. Although the winter months can be a little chilly, average daytime temperatures are still around 16 degrees. Overall, the best time to travel to Portugal is during late spring (March to May) when it’s warming up, and early autumn (September to October) when the searing heat is losing its edge.
If you want to cover a bit of everything on your trip – sightseeing, outdoor activities, some lazy days on the beach with a dip in the ocean, the best month to visit Portugal is September. It’s still hot, but not fiercely so, and the sea is probably at its warmest.
