The Lowdown
Right then, let’s have a look at what’s on offer for Sennen Cove over the next couple of weeks.
Straight up, I gotta be honest with you – it’s a tough run. The whole 16-day window is looking pretty bleak for any decent surf. The wind is almost constantly on it or cross-onshore, and the sea state is just lumpy, choppy, and messy. There’s hardly a moment where it cleans up. The water is a touch warmer than normal for this time of year, sitting at 64°, but that’s about the only good news.
We’ve got a massive gap of poor conditions right through until the 13th of September. That Sunday morning offers a slight glimmer with a 6ft swell from the W, but it’s still cross-onshore and fairly choppy. The combined wave energy is moderate at 576, but it’s just not clean enough to get excited about. The period is a solid 10 seconds, which is alright, but the wind ruins it.
The next real chance doesn’t come until the 16th of September, Wednesday morning. We’ve got a 8ft swell from the WNW, with a period of 10 seconds. The combined energy is strong at 1086, so there’s plenty of power. But the wind is still cross-shore, making it lumpy. This is a big swell, over 8ft, so it’s really only for the experts if they’re willing to fight the chop. This is probably the best on offer, but it’s a long way from perfect.
Then we drift into the second week and it’s more of the same. The 23rd of September has a 5ft WNW groundswell with a very long period of 13 seconds, and a cross-shore breeze. The energy is moderate at 627. That long period at a beach break like Sennen means it might break a bit too straight. The 25th of September has a 8ft swell with a short period of 8 seconds, and a cross-shore wind. That’s just going to be a big, messy wall.
Honestly, for a spot that’s usually very consistent, this is a real shocker. There’s not a single standout session in the whole 16 days. If you’re desperate, the 16th and 23rd are the lesser evils, but keep your expectations on the floor. With this much wind and swell, it looks more interesting for the kite surfers than anyone on a paddle board.

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 Sennen 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.
