Porsmilin Surf Forecast and Surf Report

Right then, let’s have a look at what’s on offer for Porsmilin over the next couple of weeks.

It’s a pretty rough start, honest. The first few days are a write-off. Saturday the 29th and Sunday the 30th of August are a total mess – strong cross-onshore winds, big lumpy swell, and the water’s got a proper chop on it. The combined swell energy is hammering through the 910 to 2277 range, but it’s just not surfable. You’d be daft to paddle out in that.

Monday the 31st looks a bit better. The wind swings cross-off, and the surf cleans up nicely. By Monday afternoon, we’ve got a clean 8ft swell from the west with a 10-second period and a gentle breeze. The combined energy is still strong at 1026, but now it’s rideable. It’s not a classic, but it’s the first decent window.

Then we hit a proper dry spell. From Tuesday the 1st of September right through to the end of the first week, it’s a real struggle. The swell drops off, and the wind is all over the place – cross, cross-on, onshore. Most days are scoring zero for a reason. You’re looking at a near-blank run of about five days there.

But hold on. The standout is shaping up for Saturday the 5th of September. Saturday morning we’ve got a 6ft groundswell from the west-northwest, a 10-second period, and it’s glassy. That’s right – glassy. The wind is practically nothing, just a slight air. The combined energy is a solid 686, which is moderate but punchy, and the water is about average for the time of year at 65°. That morning is the one to circle. The break is a fairly consistent sandbar, so it’ll hold the swell well. It’s a bit exposed to the southwest, which is the optimum direction, so it’ll be peeling nicely. Best on offer by a long shot.

After that, it’s a bit of a mixed bag. Sunday the 6th and Monday the 7th have some cleaner windows with cross-off and offshore winds, with swell around 5ft to 6ft from the west-northwest, but the crowds are said to be “sometimes” there, so expect company. The combined energy sits around 400 to 564, which is moderate. It’s surfable, but nothing to write home about.

The second week looks quieter. By Tuesday the 8th, the swell drops to 4ft from the northwest, and the wind is clean but the energy is down to 302. Not great. Wednesday the 9th is tiny – 2ft – and the energy is less than 100. Then, a real long-shot: Sunday the 13th of September. We’ve got a 2ft swell from the west, but with a very long 16-second period. That’s proper groundswell. The combined energy is 410, which is decent for the size, and it’s offshore from the north. That’s a point-break style wave, so it might offer some long, clean lines at Porsmilin, but it’s a long way out and not certain. Monday the 14th is similar, with a 15-second period from the west-southwest and 2ft. Keep an eye on it, but don’t hold your breath.

So, bottom line: Saturday the 5th of September morning is your best bet. Glassy, clean, and a solid groundswell. The rest of the window is spotty, with a few clean but smaller days. If you’re a beginner, the 6ft on the 5th is fine, but anything over 8ft that we saw earlier is too big. The long period swells in the second week are for experienced crew who know the sandbar.
