Sennen Cove Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s break down what’s happening at Sennen Cove for the next sixteen days.

Honestly, it’s a rough start. The first week and a half is mostly a dud. Small, weak swell and a lot of wind messing things up. The water is sitting at 66°, which is way warmer than usual for this time of year, so at least a swim won’t be a shock.

We kick off on Saturday, August 1st, with a tiny 2ft west swell, only 9 seconds between waves. The energy is weak at 55, and a cross-shore wind is chopping it up. Not worth getting wet. That same story runs through the weekend and into Monday. There’s a glassy moment on Sunday afternoon, but the swell is barely 1ft. Pass.

Tuesday, August 4th, the wind picks up from the south-southwest, pushing a 4ft swell, but it’s onshore and messy. The energy is up to 177 (moderate), but the wind ruins it. Wednesday, August 5th, sees the biggest swell of the first week—a 7ft west-southwest swell with a 7-second period. The energy hits 391 (strong), but the wind is howling at 22 mph from the west, straight onshore. It’s too big for beginners, and with that wind, it’s a kite-surfing day, not a paddle day.

Thursday, August 6th, the swell drops to 5ft, and the wind swings north-northwest, giving us a cross-shore breeze. Energy is still 258 (strong), but the surf is only marginal due to the chop. The rest of that week is a mix of tiny, wind-affected waves or clean but flat conditions.

Finally, a glimmer. Tuesday, August 11th is a standout. We get a clean offshore wind from the east at 6 mph. The swell is only 1ft, but it’s a west swell with a 10-second period—some groundswell feel. The energy is weak at 55, but the conditions are clean. This is a longboard or fun log session, just to get out there.

Wednesday, August 12th is the real deal. The swell bumps up to 3ft from the west, with that same 10-second period. The energy is 195 (moderate), and the wind is offshore from the east-southeast at 9 mph. This is the best combo of the whole forecast. The waves will have some shape, and the clean offshore wind will keep the faces smooth. Not huge, but surfable and fun.

The following Saturday, August 15th, offers a clean morning with a 2ft west-northwest swell and a cross-offshore breeze, but the energy is only 64. It’s better than nothing, but nothing special.

The wildcard is Sunday, August 16th. A 5ft west-northwest swell with a short 6-second period, but the wind is offshore from the east at 22 mph. The energy is 183 (moderate). It’s a bit too big for beginners, and the short period means it’ll be a bit lumpy. But the strong offshore wind will hold the faces up. For the experienced crew, it could offer some punchy, hollow little wedges. Long-range, so keep an eye on it—promising but not set in stone.

Bottom line: the first week is a wash. The best bet is Wednesday, August 12th, with clean offshore winds and a solid 3ft west swell. Tuesday, August 11th, is a close second for the small-wave crew. The rest? Leave the board in the car.

Rusty.
