For the most part, Portugal has a Mediterranean climate, with hot, dry summers and mild, rainy winters. Overall, the northwest of the country is cooler and the southern Algarve region is warm year-round. We've detailed more about Portugal's weather below:
Spring: March, April and May make up the spring season in Portugal. Average daily temperatures range between 14°C to 21°C, with mild temperatures and more sunshine, although rainfall is still common (especially in March). There are both pros and cons to travelling at this time: the weather might impact some of the views, but you'll also be visiting at a time when colourful flora comes into bloom and there are fewer crowds. Spring is one of Portugal's two shoulder seasons and offers a different perspective into the country from the typical summer months.
Summer: Portugal is at its hottest between June to September, with temperatures often reaching 25–35°C. There's minimal rainfall, so understandably summer is arguably the best time to visit Portugal. Activities and experiences are in full swing, although this also marks the busiest time to visit.

Autumn: The end of September and into November forms Portugal's autumn season, with temperatures ranging from 19-26°C at the start of the season to milder 15-20°C at the end. This marks Portugal's other shoulder season, with milder temperatures and fewer crowds, with regional differences between the likes of Porto in the north and the Algarve in the south.
Winter: Mid-November, December, January and February make up Portugal's winter season. Average daily temperatures during this time range between 11-16°C in the north (including Lisbon) and 16-18°C in the south. There's significant rainfall, mostly in the north, and while snow is rare in the cities it can be more common in mountainous areas.
