The Lowdown
Alright, Rusty here again. Let’s talk about Poldhu Cove.
Honestly, the first week is a struggle. The wind is on it most of the time, blowing from the southwest, and it’s turning the ocean into a mess. The water is a bit warmer than the usual for this time of year, about 64°, but that doesn’t help the waves.
The best chance you’ll get is on Friday, the 4th of September, in the afternoon. The swell is 5ft from the west, with a 11-second period – that’s a proper groundswell, so it’ll have some push and shape. The wind is from the north-northwest at 9 mph, which is a cross-offshore breeze, so the surface will be clean. The wave energy is moderate (950). It’s still a bit of a marginal call, but this is the highlight of the whole 16 days.
Saturday the 5th is a drop-off. The morning has a cross-shore breeze and a 5ft swell, but it’s not clean enough. Then the surf just fades out through the week, dropping to waist-high or smaller.
Another small window pops up on Thursday the 10th of September, in the morning. We get a clean offshore wind from the east-northeast at 16 mph, with a tiny 3ft swell from the west-southwest and a short period of 7 seconds. The energy is light (117). It’s surfable, but just barely.
So, if you’re looking for the one good session, it’s Friday afternoon, the 4th of September. The rest of the 16 days is mostly a dud for paddle surfing. The bigger, windier days might be better for a kite, but for a surfboard, it’s a long, quiet stretch.
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.
