The Lowdown
Alright folks, Rusty here. Let’s have an honest look at the next couple of weeks.
Plain and simple, it’s a rough stretch for surf. For the first four days, it’s all cross-onshore wind and lumpy, messy waves. Don’t even think about it. There’s a bit of energy on Wednesday morning, with a 7ft west swell, but the wind is howling at 22 mph, and the wave comment just says poor. It’s not gonna be worth the fight.
We finally get a small window of glassy conditions on Saturday morning, the 8th. It’s tiny, only 2ft of west-northwest swell, with a decent 11-second period. But the energy is weak. You’ll get a few clean little rollers, but it’s really only for a log or a foamie. Still, that glass is a welcome sight after all that chop.
After that, it’s more of the same. A few clean moments here and there, but the swell drops off to almost nothing. The 12th has a brief clean spell with a 2ft west swell, but again, it’s super small. The second week is mostly a write-off. The wind stays onshore and messy, even as some bigger swell shows up. There’s a pulse of energy building towards the 18th and 19th, with some 7ft and 7ft west-northwest swells, but it's all marred by strong winds and poor conditions. It’s going to be a close-out mess.
All in all, there is only one real standout, and that’s the Saturday morning glass. It’s not epic, but it might be the only clean surf you get in this whole stretch. The long period and tiny size means it could be a bit walled at the beach, so look for any corner or rip to help you out. Sennen Cove is going to be the place to be, just don’t expect a lot.
Keep the faith. When a stretch is this consistently bad, it usually doesn’t last. Forecasts change. Check back in a few days.
Seasick already,
Rusty

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 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.
