St Agnes is a busy beachbreak located in Cornwall's 'Badlands', known for its core surf community. This spot is unique because it can handle large southwest swells, making it a key location for surfers looking for reliable waves. With a sandy bottom and some rocky areas, it's a mixed bag when it comes to the environment. The area can get crowded, especially when the surf is good, and parking can be a hassle with limited spaces near the pub.

The surf here can get punchy and hollow, providing quality waves especially during medium to large swells, ranging from around 1 meter (3 ft) to about 2 meters (6 ft). The best conditions for surfing often come with a southwest swell direction, but the spot can also handle northwest swells. The waves primarily break as beach breaks, offering both lefts and rights, and the rip current on the left by the harbour wall makes for an easier paddle out. For experienced surfers, the heavier, hollow waves at low tide can be thrilling, but it’s advisable for intermediates to pick their days carefully.

Access to St Agnes is through pay car parks located close to the beach, but be advised not to drive down the slipway. The local vibe here tends to be competitive, and the lineup can get quite hectic, so be prepared for that. Most surfers come here in the winter months, particularly from December to February, making it a popular spot for those looking to catch some decent waves during the colder season.
