Alright folks, Rusty here. Let's have a look at what Sennen Cove has in store for us over the coming weeks. I gotta be straight with you from the off—this is not a classic run for this spot. The first few days are basically a write-off, with tiny, weak swell and a whole lot of nothing happening. We're looking at a quiet start from Monday, July 13th through to at least Wednesday, July 22nd. The waves are tiny, mostly around 0.7ft to 2ft, and while the wind is often offshore and clean, there’s just no energy in the water. The combined swell energy is weak, barely registering above 50, so it’s more of a paddle and a float than a surf. Don't bother suiting up for that.
Now, things get a bit more interesting towards the end of the month. From Friday, July 24th, we see some more size but it’s messy and onshore, so no good. The real story, and the only standout on offer, is Sunday, July 26th. The morning shows a clean-ish 4ft swell from the SW with a period of 6 seconds, but the wind is a fresh cross-onshore, making it lumpy. That afternoon, though, is when the ocean wakes up. We get a solid 7ft swell from the W, but it's coming with a strong onshore wind. The energy jumps to a strong 706, but for wave-riding, it’s going to be a messy, blown-out affair. This continues into Monday, July 27th (over a week away, mark it), with the swell building all the way to 8ft in the morning and 10ft in the afternoon. The combined energy hits a huge 1322, but the wind is a strong cross-onshore, making it chaotic. This is proper big, powerful stuff, and with onshore winds, it's only for the most experienced, and honestly, looks more like a kite-surfing setup than a paddle-surfing one at a beach break like Sennen.
Given the exposure and the optimum swell direction from the West, this big pulse has the right angle, but it's all about the timing of the wind. If the wind swings, it could be a memorable day for experts, but as it stands, it’s a wild, powerful ocean. For the rest of us, it’s a long wait. Hang in there.
Rusty.

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.
