The Lowdown
Alright folks, Rusty here. Let’s break down what we’ve got coming for Poldhu Cove over these next couple of weeks.
Honestly, the first week is a total bust. From now through about the 12th of September, it’s rough. The wind is either cross-shore or straight onshore, and the surf is choppy and unrideable. You’ll see some swell come through, like 7ft on the 7th, but the wind just tears it apart. That’s a solid week of nothing worth getting wet for.
Finally, on the morning of Sunday the 13th of September, we get a little window. There’s a clean look with a gentle cross-offshore breeze and a 4ft west swell. The water is a touch warmer than normal for this time of year, about 64°. The energy is light, so it’s not going to be firing, but for a spot that’s inconsistent, you might sneak a few tidy ones. Keep your expectations low.
But here’s the one that matters. Wednesday the 16th of September morning is the real deal. A solid 10ft west swell, a light offshore breeze from the NNW, and clean conditions. The energy is proper (1328), so there’s real power in the water. That’s a groundswell at 9 seconds, and at nearly 10ft, this is strictly for the experts. The swell direction is dead-on for what Poldhu likes. It’s going to be big and it’s going to be good.
Thursday the 17th of September will also have a 10ft west swell, a 10-second period, and massive energy (2954), but the wind is onshore from the southwest. That’s going to make it messy and blown-out. Only for the brave and the very experienced.
After that, it drops off and gets messy again. Your best bet, and the only real standout, is the 16th morning. Get it while it’s clean.
Rusty.

A general guide to surfing at Poldhu Cove can be found by selecting the local surf guide option on the grey menu.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
