The Lowdown
Right, let’s get to it. For the next week and more, it’s grim at Poldhu Cove. The swell shows up, but the wind’s going to trash it. We’re talking choppy, bumpy, and blown-out seas, with energy readings starting weak at 68 and climbing to a massive 2100 by the 29th, but that day also brings 50 km/h winds and 3.5m of onshore slop. That’s strictly kite-surfing conditions. Even the smaller days like the 27th are getting messed up by onshore breeze. It’s a solid stretch of unridable surf until things finally settle.
Finally, after all that onshore junk, there’s a light at the end of the tunnel on Saturday the 5th of September. The wind finally turns offshore from the NE at only 10 km/h, and we still have a decent 6ft swell running at 11 seconds. This is proper groundswell, with the energy at a strong 881. This is the first real chance to get a clean wave. The surface will be glassy, and it’s been a long time coming. It’s a standout just because the conditions finally align. Heads up, the break is inconsistent, so you’ll be waiting for waves, and with crowds possible, you won’t be alone. The afternoon looks like it picks up a seabreeze, so be there in the morning before it gets rippled.
That taste is short-lived though as the wind comes back onshore for the 6th and 7th. But then we get the real deal on Wednesday the 10th of September. This is the one. The ENE offshore wind at 20 km/h will be blowing clean, and we are looking at a solid 10ft of west-southwest swell with 11-second period. This is big, powerful groundswell, with energy readings of 1685 in the morning and over 2000 (2091) by the afternoon. This is definitely expert territory. It’s a lot of ocean moving. That swell direction is perfect for this break. Because it’s over 2.5m, it’s only for the experienced crew. The long period means longer lulls between sets, but those waves will have so much more punch when they hit.
So, there you have it. You’ve got a lot of windy, messy days to get through. The first proper chance is on the 5th, but the big one to save your energy for is the 10th. That’s when the stars align with size, direction, and clean offshore winds. Stay patient through the first week and get ready for that second Saturday.

Information about the Poldhu Cove Surf forecast
The above surf forecast table for Poldhu Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Poldhu Cove can be found by selecting the local surf guide option on the grey menu. Our Poldhu Cove surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Poldhu Cove) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
Poldhu Cove is 12 km (7 miles) from The Lizard. If you plan a holiday in South Cornwall, look for hotels and other accommodation in The Lizard. The Lizard has rooms for a wide range of budgets as well as car hire and transport links.
