The Lowdown
Alright folks, Rusty here. Let’s have a look at what Sennen Cove has got cooking for us over the next couple of weeks. I’m not going to lie to you, it’s a bit of a rough start.
The opening week is pretty grim. We see some solid easterly winds early on, blowing straight offshore, which cleans things up nicely, but the swell is tiny. We’re looking at a weak 1ft to 2ft on Monday the 24th and Tuesday the 25th. The swell energy is low, sitting around (54 to 144), so it’s clean but pretty much unrideable. A frustrating combination for sure. The wind stays helpful through Tuesday, with a moderate offshore, but there’s just not enough push.
Wednesday the 26th goes light, but the wind swings cross-shore and the swell stays weak and short-period. Not much going on.
Thursday the 27th is a bit of a tease. The morning brings a 5ft swell from the SW, with a short period of 7 seconds, and a light cross-shore wind. The energy picks up a bit (260), but the cross-wind and short period keep it marginal. It might look tempting, but it won’t be clean.
Late on Friday the 28th morning we finally get a real window. The wind is a gentle offshore from the east, and the swell bumps up to a clean 4ft from the W with an 8-second period. Wave energy is moderate (311). It’s not pumping, but after all the quiet, this is your best bet for a proper surf. It’ll be clean and fun for a beginner-friendly wave. You’ll be sharing it with the odd other soul, as crowds are a possibility.
That’s the standout for the first week.
After that, it goes a bit sideways again. Saturday the 29th and Sunday the 30th get messy with strong cross-shore and onshore winds. Swell height pushes up a bit on Sunday to 8ft, but the wind is a strong cross-onshore, making it a choppy mess.
Then, the end of the forecast period gets interesting, but not exactly surfable for most. From Monday the 1st of September through the 8th, there are some serious pulses of energy. We see a massive 16ft swell on Monday the 7th of September, with a very long 17-second period. The energy readings are massive, going up to (13,773). The problem is, it’s all coming with onshore winds and, at times, rain. For a beach break like Sennen Cove, that much long-period, wind-blown swell will just be a washing machine. It’ll be a sight to see, but unless you are a total expert looking for a survival session, it’s a no-go. The setup looks more interesting for kite surfing than paddle surfing on those big days.
So, to sum it up: the clear standout is Friday morning, the 28th of August. Get in the water early for a clean, gentle offshore session. The rest of the period is either flat, onshore, or way too big and messy for a good time.
Keep an eye on it, though. Forecasts change.

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.
