Mosteiros Left is a surf spot located along the coast that offers an average experience for surfers. The scene consists of a rocky line-up and is known for its left-breaking waves. It's not a heavily crowded area, making it a decent choice if you prefer to surf without a lot of company. There are no facilities, but parking is usually easy to find.

The waves here can be fast and hollow when the right conditions come together. The best time to surf is during mid to high tide, with a south-west swell coming in at around 4ft (1.2m). The optimal swell direction is from the west, but it can also handle south-west swells. A south-east wind is preferred to get the best ride. Though it breaks consistently, don’t expect it to be firing all the time—it's often just okay.

This spot is better suited for intermediate surfers due to the rocky seabed and potential rip currents. If you're a beginner, it’s probably best to look for a different beach. With the right swell and conditions, Mosteiros Left can provide some fun waves, but be prepared for it to be hit or miss.
