Portugal has mild temperatures year-round, especially in comparison to the rest of most of Europe. While March is wetter and cooler than the summer, rain levels tend to decrease as spring emerges. This change in weather can present a golden opportunity to miss the crowds and high prices of the warmer months and visit Portugal for some much-needed sunshine.
What to Pack
Although the weather varies depending on where you're visiting in Portugal, overall the temperature will hover at around 57 F with the possibility of light showers.
With that in mind, you'll want to bring jeans or long pants, a light jacket, and an umbrella if you see rain in the forecast. Sweaters and scarves are nice to layer for the evening when it gets chillier after the sun goes down.
Lisbon: Perfect for Sightseeing

Because the town won't be full of tourists, day tours will be much less hectic than usual. You also shouldn't have much trouble booking a centrally located hotel at a reasonable price.
The end of March also sees the nearby Obidos International Chocolate Festival, so you shouldn't need another reason to visit the area!
