The Lowdown
Alright folks, Rusty here. Let’s have a proper look at what’s coming down the line for Poldhu Cove.
Straight up, the next couple of weeks are a real mixed bag. We've got a long stretch of poor conditions to start, with messy winds and onshore slop. Don't even think about paddling out until we get past the first week of September. There's a big gap of no-go days from now all the way through the 6th of September. It's not looking good for a while.
The first real glimmer of hope shows up on Monday the 7th of September. We get a proper window with a fresh offshore breeze from the NNE at 22 mph, cleaning up a solid 8 ft swell rolling in from the west with a 10-second period. The wave energy is strong. The water temperature is around 65°, which is a touch warmer than normal for the time of year. That Monday morning is the standout – clean, powerful, and with that offshore wind, Poldhu Cove should have some decent shape. It's a fairly exposed spot catching a SW optimum, so the westerly groundswell will wrap in nicely. That said, the swell is pushing over 8 ft in the afternoon on Monday (8 ft), so that session is better left for the experienced heads. Expect it to be a bit punchy. Crowds are "sometimes" here, so you might not be alone, but it'll be worth the company.
After that Monday window, things get shaky again. Tuesday the 8th has some small clean-ish conditions but the wave energy drops right off. Then Wednesday the 9th of September looks big again – a 10 ft swell from the WSW with an 11-second period and strong energy – but the wind is fresh and cross-onshore, making it a lumpy, messy affair. That one's more for the big-wave crew or kite surfers if you've got the gear. It's not a paddle surfer's paradise.
So, to sum it up: the whole first week is a washout. The one true standout is Monday morning on the 7th of September at Poldhu Cove. Get it while it's clean and offshore. After that, it's a chase for a clean window amongst the wind.
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).
Further information to help with frequently asked questions about our surf forecast for Poldhu Cove may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
