The Lowdown
Alright folks, Rusty here. Let’s be straight with you—this 16-day window for the region is a tough one. We’ve got a long, frankly frustrating gap at the start with nothing worth paddling out for, and the pickings stay slim right through. The first real chance of a wave doesn't show up until Thursday the 3rd of September, and even then it’s marginal. Before that, we’re looking at a solid five days of poor surf from Saturday the 29th of August right through to Wednesday the 2nd of September. The Saturday actually kicks off with some size—8ft to 12ft—but it’s a messy, wind-affected riddle with a strong cross-shore, so forget about it. That’s the kind of setup that’s more interesting for a kite surfer than a paddle surfer. The water is sitting at 65°, a touch warmer than normal for this time of year.
Now, if you’re desperate, Thursday the 3rd of September morning offers the only glimmer. Maenporth will see a 6ft swell from the WSW, with a period of 8 seconds, and a moderate cross-offshore breeze from the W. It’s clean, but the energy is moderate (458). The swell is a bit short-period, so it won’t have much grunt, and it’s only a marginal call. The break is sheltered and inconsistent, so don’t expect a classic session. After that, it’s back to tiny, flat dribble for days on end—mainly 0.3ft to 0.7ft from the SSW with long, drawn-out periods, but no power.
The only other faint pulse comes on Thursday the 10th of September, when a 8ft to 10ft WSW swell rolls in, but it’s onshore and choppy, with moderate energy (591 to 1146). That’s messy and too big for beginners, and with the wind ruining it, it’s not a standout. The very end of the run, on Sunday the 13th of September, goes glassy with a tiny 1.0ft groundswell from the WSW, but it’s just a tease. Honestly, the best advice is to wait for a better forecast. The good news is, breaks in this area do pick up, and forecasts can change. Hang tight.
Rusty.
