The Lowdown

Right then, let's have a look at what's coming our way for Sennen Cove. Honestly, it's a bit of a mixed bag, and you're going to need some patience. There's a long stretch of poor conditions before we finally see something that's worth getting excited about.

Alright, so the immediate outlook is a tough one. From Sunday the 13th through to Thursday the 17th, it's pretty much a write-off. The wind is relentless, coming from the southwest and west-northwest, mostly cross-onshore, making a proper mess of things. The swell is there, mind, between 5 and 8 feet, but it's just blown-out and lumpy. The water's about 63°, a touch warmer than usual for this time of year, but that's little comfort when you're battling a cross-onshore chop.

The whole of the following week doesn't offer much either. A few days of onshore winds and lumpy surf keep the conditions poor right through to the 19th of September. There's a lot of energy out there, with some moderate to strong combined swell readings, but it's all wasted.

We finally get a glimmer of hope on Sunday the 20th. The morning is still marginal with a light cross-on breeze and 5-foot swell, but the afternoon looks much more promising. The wind swings to the north-northwest and goes light cross-shore, and the swell period jumps up to a very long 14 seconds. This is proper groundswell, and it's going to wrap in with some serious push. The combined energy is solid, so there's a lot of power behind it. Keep in mind, with a period that long, the sets will be a bit more spaced out, and it might break a little too straight on the beach, but it's the cleanest we've seen.

Monday the 21st has a slight chance early with a light cross-shore breeze and 4-5 foot swell, but it's quickly overtaken by onshore winds. After that, we're back into the wilderness. From the 22nd right through to the 28th of September, it's a mix of fresh offshore winds and tiny, weak swell. The wind is from the east and south-east, which is offshore, so it'll be clean, but the swell drops right off. We're looking at heights around 1 to 3 feet and combined energy readings down in the dumps. It's just too small and weak to be any good for surfing.

The best of the whole run is undoubtedly Sunday the 20th of September, in the afternoon. That 5-foot of west swell with a 14-second period and light cross-shore winds at Sennen Cove is the standout. It's not perfect, but it's the only window where the conditions align to give you something decent. Don't get your hopes up for anything else, though. The rest of the forecast is a long, dry spell.

Information about the Sennen Cove Surf forecast

The above surf forecast table for Sennen Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sennen Cove can be found by selecting the local surf guide option on the grey menu. Our Sennen 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 (Sennen 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 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.
