Hell's Mouth (Porth Neigwl)
Hell's Mouth — Porth Neigwl — is one of the most powerful and exposed beaches in Wales. Sitting on the southern coast of the Llyn Peninsula in North Wales, this sweeping four-mile bay faces south-west and hoovers up any Atlantic swell that wraps into Cardigan Bay. When a solid W or SW groundswell is running, Hell's Mouth delivers heavy, punchy waves that can rival anything in the UK. This is not a beginner's beach. The bay is notorious for strong rip currents that run along the beach and out through the centre, and the remote location means there are no lifeguards. The beach is backed by low cliffs and farmland with no facilities at all. On its day, Hell's Mouth produces fast, hollow beach break peaks across shifting sandbars, with the best waves often found at the eastern end near the cliffs. Offshore in northerly or north-easterly winds.
Conditions look mixed today with moderate onshore wind and a dropping swell period through the afternoon. Best bet is the early morning push before the wind picks up. Tomorrow looks cleaner with a slight shift in direction.
