Praia Grande is one of the notable surf spots in the Lisbon area, known for its consistent waves and sandy beach. It's a popular destination for surfers of all levels, especially beginners looking to catch some waves. The beach itself has a laid-back vibe, making it a great place to spend a day surfing or just hanging out with friends.

The surf here tends to vary with the tides. At low tide, you can expect long but often slower waves, while as the tide rises, the waves become quicker and shorter, especially in the shorebreak. The most optimal swell direction for Praia Grande is from the Northwest, with other useful swells coming from the Southwest and North. The spot can handle swell sizes starting from around 2 feet (about 0.6 meters), and the waves break over sand, providing both lefts and rights for surfers. Ideal conditions feature preferable winds coming from the East and can work well at any tide height - low, mid, or high.

Since the beach break is versatile, it's busy when the waves are good, so be prepared for some company in the water. It's a reliable spot for a fun day of surfing, especially for those just starting out.
