The Lowdown
Alright folks, let’s talk Poldhu Cove for the next couple weeks. The early going is a bust – we’re looking at a solid five or six days of rough, messy surf with nothing worth paddling for. Patience is the game.
Come Monday, September 21st, the light finally turns green. The wind goes light and cross-off from the east, and we get a 4ft swell from the west with a 12-second period. That’s a long-period groundswell with some real push for its size. It’s small, clean, and playful – perfect for a log or a funboard. Water temp is about average, nothing weird. Crowds are only sometimes around, so you might score a session with just a few friends.
Tuesday the 22nd is a gem in the afternoon. Glassy conditions – dead calm – and the swell holds at 4ft from the west with a 10-second period. It’s going to be smooth as glass. That kind of day doesn’t come around often.
Now the big one – Wednesday, September 23rd. The afternoon is an absolute standout. We’re looking at a 7ft groundswell from the west, with a long 13-second period. That’s a proper groundswell with serious energy. The combined swell energy is strong – up around 1672 (moderate to strong). The wind stays light and cross-off from the east, so the waves will be clean, lined up, and powerful. That’s too big for beginners – you need experience. Optimum direction is SW, and this spot loves that. If you can get out that afternoon, this is the session of the forecast.
After that, Thursday the 24th drops off but stays clean, with waist-high sets and gentle cross-off wind. Still fun, just not as punchy.
From the end of September into early October, the swell fades fast and the wind cranks up from the east. Clean but tiny – the combined energy drops below 100. Not worth the effort.
Bottom line: the action is all on that Wednesday the 23rd. Make it happen.
