The Lowdown
Alright folks, Rusty here. Let’s be straight with you. This 16-day outlook for Sennen Cove is a long, hard watch. To be honest, there’s nothing good on offer for the entire stretch. The forecast kicks off with a few tiny, weak waves but the quality is just poor, and it never really recovers into anything worthwhile.
Right from the start on Saturday the 18th, we’ve got a tiny 1ft west swell with a weak 8-second period, but it’s blown out by a cross-shore wind. Not worth a paddle. The water temp is sitting at 65°, which is a touch warmer than normal for this time of year, but that’s about the only positive. Sunday the 19th and Monday the 20th see a little bump in swell size, but the wind is all over the place, and the energy is still weak.
Tuesday the 21st is the closest we get to anything decent. The morning has a light breeze and a clean 3ft north swell, and by the afternoon it turns glassy with a 3ft north swell. The combined energy is still low, and the waves are ordinary. You could probably get a few knee-high wobblers in the glassy conditions, but it’s not exactly a session to write home about.
From Wednesday the 22nd all the way through to the end of the month, it’s a steady diet of poor surf and deteriorating conditions. The swell tries to build, hitting 5ft on Thursday the 23rd with moderate energy, but the north wind is cranking at 18 mph, ruining any chance of clean waves. The week of the 26th sees the biggest swell of the period, with 7ft west swell on Sunday, and combined energy climbing. But that’s all onshore, messy, and blown out. That’s kite-surfing territory, not smooth paddle surfing.
The final days into early August don’t offer any redemption. The swell stays around 5ft, there’s fresh cross-offshore wind, but the waves are still listed as “poor surf conditions.” The last morning on August 2nd shows a clean 3ft west-northwest swell with offshore wind, but the energy is weak. It’s just not happening.
So there you have it – a long blank run. Sennen Cove can be a moody spot, and this stretch is one of those times when the ocean just isn’t cooperating. Forecasts can change, but right now, I’d leave the boards in the van.
Rusty.

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.
