The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for Sennen Cove over the next couple of weeks.
Right off the bat, I gotta be straight with you: it’s a tough stretch ahead. There’s a big gap at the start with nothing worth paddling out for. The first few days are flat or tiny, with a few tiny, weak swells showing up but they’re just not doing anything. You’re looking at a dry spell from now until about the 12th of August. After that, we get some more size, but the wind just won’t play ball. This is a spot that needs clean conditions, and we’re not getting them.
The first real chance of anything half-decent arrives on Wednesday the 12th of August. The swell bumps up to 4 ft from the W, with a period of 10 seconds. The combined energy is moderate at 267. That's some proper push, but unfortunately, it’s coming with a cross-onshore wind, so it’ll be choppy and messy. Not the clean lines we love.
Moving into Thursday the 13th of August, the swell holds around 4 ft from the W, period 10 seconds, and the energy is solid at 339. It’s a genuine groundswell, but again, it’s onshore wind. The morning has a bit of potential with lighter onshore wind, but it's still not clean. This is more of a look-and-see situation.
Friday the 14th of August is a bit of a teaser. The swell drops to 2 ft from the W, period 8 seconds. The energy is a weak 122. But the morning wind is glassy – flat calm. It’ll be clean, but the waves are tiny. A longboard might get you a glide, but don't expect any power.
Saturday the 15th of August sees another pulse, with the swell at 3 ft from the WSW, period 8 seconds, and energy at 95. That’s weak. The morning is cross-onshore, so it’s not great.
Then we get into the second week, and it’s more of the same story: more size, but the wind is a nightmare. Sunday the 16th of August has a 3 ft swell but a short, weak 6-second period and a cross-onshore wind. The real kicker comes on Monday the 17th of August. The swell jumps to 5 ft from the W, period 7 seconds, with moderate energy at 239. The morning wind is a clean cross-offshore from the NNE. That’s your best chance for the whole forecast, but the swell is a bit short-period and lumpy. It’s the only window that looks truly clean.
After that, from Tuesday the 18th of August onwards, the swell stays in the 4 ft to 5 ft range, with long-period energy hitting over 500 on the 20th, but it's all cross-onshore or onshore, with moderate to fresh breezes. The waves will be there, but they’ll be a choppy, blown-out mess. Not worth the paddle for a clean session.
The standout? If you're desperate for a paddle, the morning of Monday the 17th of August is the one to circle. The swell is 5 ft from the W, and the cross-offshore wind will make it clean. The period is short at 7 seconds, so it won't be the best shape, but it’s the cleanest wave in a very dirty forecast. For the rest, it’s a waiting game.
Stay tuned, forecasts can change, but right now, it’s a lean run.

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.
