The Lowdown
Alright, buddy, let’s talk about Sennen Cove. This forecast is a story of two halves: a whole lot of nothing, then a proper bang at the end. You’re gonna have to be patient.
The first week and a half is a real dry spell. From Friday the 24th of July all the way to about the 5th of August, the surf is mostly flat or junk. The swell is tiny, from 0.6ft to about 3ft, and the wind is just messy – cross, cross-on, and strong onshore. A few mornings look clean, like Monday the 27th with a 5ft swell and light offshore wind, but the energy is weak (329) and the conditions are described as marginal. It’s just not going to be a good session. The 31st of July (Friday) morning is glassy, but it’s only 2ft with a 7-second period – barely a ripple. That’s a long, tough stretch for a beach that’s usually very consistent, so it stings a bit.
But hold on, because the light at the end of the tunnel is bright. The real standout is Friday the 7th of August. The morning session at Sennen Cove is your best bet. We’re looking at a proper 7ft swell from the SW, with a light offshore breeze from the NE. That means clean, glassy faces. The combined energy is a solid 432, so there’s real power in the water. The swell direction is perfect for this exposed spot. This is the one to mark on the calendar. It’s a long-range call, but everything lines up. It’s not for beginners at that size, but for anyone who’s comfortable, this is the best on offer.
The swell sticks around into Saturday the 8th of August, with another 8ft from the WSW, but the wind goes cross-shore in the morning and then cross-on in the afternoon, so it won’t be as clean. Still, there’s a ton of energy (861 to 932), so the waves will be there, just a bit lumpy.
The water temp is sitting at 66°F, which is a touch warmer than normal for this time of year, so you can leave the thickest wetsuit at home.
Alright, I’m done. Wait for that Friday the 7th of August morning. That’s your day.
Rusty.

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.
