We can say that Portugal has its surf season throughout the entire year. However, the best months with more consistency and bigger swells are during the winter months and autumn. During spring there is also a good consistency of swell with little wind and great weather. No doubt a great time to visit our surf camps. The storms that occur in the North Atlantic during winter produce swell that reaches the coast of Portugal who produce many of the best waves worldwide. That’s why the Rip Curl Pro Portugal takes place every year in mid October in Peniche.
The southern coast in the Algarve also produces good waves during the winter biggest swells.
Summer time is a great season to visit Portugal but mainly recommended to beginners, since you can't expect big riding waves. However, towards the end of the summer, September, is a great month and when the first swells start pumping.
