The Lowdown
Alright folks, Rusty here. Let’s break down what Poldhu Cove is serving up for the next couple of weeks. Honestly, the first week and a half is a bit of a struggle. Lots of small, weak swell and conditions that just don’t line up. There’s a long stretch with no real surf, but things finally perk up around Tuesday the 18th of August.
The water is 66°F right now, which is a touch warmer than usual for this time of year – not a bad thing if you’re in a shorty.
The first hint of something surfable comes on Wednesday the 12th of August. The afternoon goes glassy, with a tiny 3ft swell from the WSW (moderate energy at 142). It’s surfable, but nothing to write home about.
Thursday the 13th is a bit better, with 4ft from the west and the energy hitting 338 in the morning. The wind is cross-off from the north, keeping it clean. Still a marginal day – worth a look but don’t expect perfection.
Then it’s back to the doldrums. Friday through Monday the 17th are all poor – small, weak, or blown out.
The one and only real standout in this whole forecast is Tuesday the 18th of August. Tuesday morning, Poldhu Cove is glassy and calm, with a 5ft west swell and moderate energy (272). The wind is light from the west, giving us those perfect glassy conditions. The period is only 8 seconds, so it’s a short-period wind swell, but at that size with no wind, it’ll be clean, fun, and perfect for a beginner. Just keep in mind the break is inconsistent, so you’ll have to wait for the sets.
After that, Wednesday the 19th starts glassy with 4ft, but it gets chopped in the afternoon. Thursday the 20th offers some clean cross-off conditions in the afternoon with 4ft from the west, but again, it’s just ordinary.
From the 21st onward, it’s clean but tiny, with strong easterly winds. The swell is gone, under 3ft. Kite surfers might enjoy the breeze, but for us paddle surfers, it’s a waiting game.
So, the only morning to really lock in is Tuesday the 18th of August. Glassy, 5ft from the west, clean as can be. That’s the one.
Stay salty,
Rusty

Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
