The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s in store for the next couple of weeks over at Sennen Cove.
Right off the bat, I gotta be straight with you – the next week and a half is looking pretty grim. We’re talking a real flat spell with hardly a wave worth paddling out for. The water is sitting at a touch warmer than normal for this time of year, about 65°F, but that’s about the only good news. We’ve got a long stretch of poor surf conditions from now all the way through the end of the month. The swell is tiny, mostly around 1.0ft to 3ft, and the period is short, so there’s just no energy in the water (combined energy values are mostly under 100, some barely breaking into double digits). The winds are a mix of cross and cross-off, but with such small waves, it’s just not worth getting wet.
We see a little flicker of hope on the morning of Monday the 27th of July. The swell picks up to 5ft from the WNW with a period of 9 seconds, giving us a combined energy of 283 – that’s moderate energy, finally. The wind is a light cross-off from the NE at 9 mph, which will keep things clean. The forecast says "expect good surf conditions." This is the best on offer in the whole run, but even then it’s only a 2-out-of-10. It’s small, but for a surf-starved stretch, it’s our best chance. Sennen Cove is exposed to the west and that WNW swell direction is right in the sweet spot. It’s a beginner-friendly break and very consistent when it does get swell, so this could be a fun little session for the learning crew. The crowd situation is "sometimes" here, so you might have a few others with the same idea.
After Monday, the 28th of July (Tuesday) has a glassy afternoon with the wind going almost dead calm from the NE at 3 mph, but the swell is only 2ft and the energy is weak (63). It’s clean, but really small.
Then we hit another dead zone. From the 29th of July through the 4th of August, it’s back to mostly poor surf conditions with tiny swell and unfavourable cross-shore winds. The energy is weak, barely cracking 100. The 1st of August (Saturday) sees a bump in size to 6ft from the SW, but that comes with a strong onshore wind from the NW at 12 mph, making it a messy, choppy mess. That’s one for the experts only, and even then it’s not great.
So, to sum it up: keep your eyes on Monday the 27th of July morning. That’s your one genuine window for a clean surf in the next two weeks. After that, it’s a long, dry spell. The setup looks more interesting for a kite surfer than a paddle surfer on most days, with that wind and small chop. Don’t hold your breath, but forecasts can 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.
