Sennen Cove Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what’s coming up for Sennen Cove. It’s a bit of a rough start, but we’ve got a serious treat waiting for us if we’re patient.

Right now, and for the next several days, the ocean is in a foul mood. We’ve got a big, powerful westerly swell hammering the coast, but the wind is a mess. For the first week, from Saturday the 29th of August right through to the following Saturday the 5th of September, it’s a write-off. The wind is mostly cross-onshore or onshore, blowing a fresh to strong breeze, often 18 to 25 mph. The swell is mostly over 7 ft, topping out at 12 ft, and it’s just a lumpy, choppy mess with poor surf conditions. The combined wave energy is strong, hitting 2002 on Saturday afternoon, but with that wind, it’s not for paddle surfing. With that size and wind, a beach break like this is going to look more interesting for kite surfing. The water temperature is 65°, which is a touch warmer than normal for this time of year.

We finally get a break in the wind on Monday the 7th of September. The morning is the real standout. We’ve got a clean 7 ft swell coming from the west with a long 11-second period, and the wind is light offshore from the east at just 6 mph. The combined wave energy is a solid 1230, and conditions are described as excellent for experienced surfers. The swell is a bit over 7 ft, so it’s going to be a powerful one, best left to the crew who know what they’re doing. The afternoon is a bit more marginal, with a stronger cross-offshore wind that’s likely to mess things up a bit.

Looking further ahead, the second week gets interesting again. On Thursday the 10th of September, we see a 8 ft to 10 ft westerly swell, but the wind is a bit cross or cross-off, making it marginal. The real firecracker is Friday the 11th of September. The morning session shows a massive 10 ft west swell with a very long 14-second period, pushing the combined energy to an incredible 3282. The wind is light from the south at 9 mph, but it’s a cross-shore, so it might have a bit of a chop. That’s a lot of water moving, and with that period, it’s going to be a serious groundswell. This is one for the experts only, and it’s a long-range call, so keep an eye on it.

Then, to finish the forecast, we’ve got Sunday the 13th of September. The morning is glassy. Absolutely flat calm. A 5 ft west swell with a 12-second period, no wind at all, and an excellent surf forecast. The afternoon holds a 7 ft west swell, still glassy, with light winds. That Sunday is looking like a proper beauty day for a surf.

So, to sum it up: the first week is a right-off for clean waves. The clear standout is Monday the 7th of September for a big, powerful, clean west swell with offshore wind. The second standout is Sunday the 13th of September for a glassy, clean day that should be much more manageable. That Friday the 11th is a monster for the brave, but it’s a long way out.

Rusty.
