The Lowdown

Alright folks, Rusty here. Let’s have a look at what Sennen Cove has in store for us over the next couple of weeks.

Right off the bat, there’s a bit of a wait. The first real chance to get wet is Wednesday morning, the 12th of August. We’ve got a 3 ft swell from the west-southwest, with a 10-second period pushing through. The combined swell energy is sitting at 167 (moderate). The wind is a moderate breeze from the east-southeast, which is offshore here, so it’s going to be clean. The water temp is about average for the time of year. It’s not a standout day, but it’s a start.

Wednesday afternoon sees the swell bump up a touch to 3 ft from the west, still with a clean face thanks to a light cross-offshore breeze. Energy is still moderate at 179. It’s surfable, but nothing to write home about.

Now, Thursday the 13th through to the end of the first week is a write-off. We get a bit more size on Thursday morning with 4 ft, but the wind swings around to a moderate cross-onshore from the north-northwest, making it choppy and messy. The same story continues through Friday, Saturday, and Sunday – the wind is all over the place, and the energy drops right off. Sunday morning sees a pathetic 2 ft swell with only 43 (weak) energy. There’s a gap of several days here with no real surf on offer.

The following Monday and Tuesday, the 17th and 18th, are tiny and blown out. Not worth paddling out for.

Then we get a big pulse of swell on Wednesday the 19th of August. We’re looking at 7 ft to 7 ft from the west-northwest, with a long 11-second period. The combined energy jumps way up to 1032 on Wednesday morning (strong). This is a proper groundswell. The problem is the wind. It’s a strong breeze straight onshore from the west-northwest, which will make it a messy, blown-out mess. At this size, it’s getting too big for beginners, but the wind is so bad even the experts won’t be stoked. This is a kite-surfing day, not a paddle day.

Thursday the 20th is even worse. Swell hits 10 ft from the northwest, with energy at 1693 (very strong). The wind is a near-gale from the northwest, cross-onshore and completely blown out. That’s for experts only, and even then, it’s going to be a survival session. The wind stays strong on Friday the 21st, but the swell drops back to a small 2 ft. Not worth it.

The second week is a bit of a mixed bag. Saturday the 22nd afternoon sees a 7 ft swell from the west-southwest, but with a short 7-second period and a moderate cross-onshore wind, it’ll be choppy. Sunday the 23rd morning has a 7 ft swell from the west with a moderate onshore wind – again, poor conditions. The energy is moderate at 527.

The best option in this whole period, if you are desperate, is Wednesday the 19th of August for the size, but the wind is a disaster. Honestly, looking at the whole 16 days, there is no true standout. The wind is simply too strong and from the wrong direction most of the time, or the swell is too small. The conditions just aren’t cooperating for Sennen Cove.

Stay patient, lads. It’ll turn around.

Rusty.

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.
