The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Sennen Cove.

Right off the bat, I gotta be honest with you – this forecast is a tough one. We’ve got a 16-day window, but it’s a long, dry spell before anything worth paddling out for shows up. The first recommendation doesn’t come until Thursday the 23rd of July, and even then, it’s barely a whisper. The whole run from now until then is a write-off.

Thursday 23rd July is the first glimmer. We’re looking at a tiny 3ft swell from the north, with a short period of 6 seconds. The wind is light and cross-offshore from the NNE, which will keep the surface clean. It’s surfable but very ordinary, with weak wave energy (95). It’s a small day for getting the log out, not for any real power.

The rest of that week and into the next is a real struggle. Friday 24th, Saturday 25th, and Sunday 26th are all poor. The swell tries to build on the 25th and 26th, hitting 5ft and then 6ft, but the wind is a messy cross-onshore, chopping it all up. The wave energy picks up on Sunday 26th to 344 (moderate), but it’s useless with that wind.

We finally get a bit of a cleaner look on Monday 27th July. The swell is 5ft from the WNW with a period of 8 seconds, and the wind is a lighter cross-onshore from the NNW. It’s still choppy, but the energy is there at 317 (moderate). It’s a “maybe” day, not a standout.

The real standout, if you can call it that, is a very long-range glimpse. On Tuesday 4th of August, the afternoon sees a jump in swell to 5ft from the WSW with a period of 7 seconds. The wind is a cross-shore from the south at 19 mph, which is lumpy, but the wave energy is solid at 240 (moderate). It’s a week and a half away, so treat it with a pinch of salt, but it’s the best power on offer.

Wednesday 5th August follows with a similar story: 4ft swell from the west with 8-second periods, but the wind is a fresh cross-onshore and it’s lumpy. Energy is 269 (moderate). Not a clean day.

For this whole stretch, the water temp is sitting at 65°F, which is a touch warmer than normal for the time of year, so you might get away with a thinner suit.

The setup at Sennen Cove is a very consistent, exposed beach break, but with mostly cross-onshore winds and messy conditions, it’s not looking like a paddle-friendly zone. When the wind is up and the quality is poor, this spot starts looking more interesting for the kite crew than us surfers.

It’s a bleak run, but the swell windows are there. Keep your eye on that Monday the 27th for the cleanest morning, and the 4th of August for the most size. Hang in there.

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.
