The Lowdown
Right, Rusty here again. Let’s break down what’s happening at Porsmilin over the next couple of weeks.
The first week is a bust. Thursday the 27th of August kicks off with tiny, onshore junk – 0.8ft from the southwest and a gusty SSW wind making a mess of things. That sets the tone for the next several days. We’re looking at a stretch from Thursday the 27th right through to Friday the 4th of September where the wind is just never your friend. It’s mostly cross-onshore or straight onshore, and the surf quality is rated as poor. The swell does build up, especially around Saturday the 29th and Sunday the 30th of August with 7ft to 10ft of WSW windswell, but with 22-25 mph winds tearing it up, it’s a choppy, blown-out mess. That’s more kite-surfing territory than paddle surfing, honestly.
We finally get a glimmer of hope after a long, flat-looking week. The standout comes on Saturday the 5th of September. The morning is the real deal – glassy conditions with a light 3 mph breeze from the NNW and a solid 8ft of west swell. That’s a proper groundswell with a 12-second period, so it’s gonna have some punch. The wave energy is strong, and with that offshore wind, Porsmilin’s sandbar should be shaping up nicely. Just a heads up, though: at 8ft, this is really for experienced surfers only. The afternoon is still okay with clean 8ft waves, but a light cross-onshore breeze creeps in.
Sunday the 6th of September holds size, with 8ft west swell and lighter onshore winds in the morning that are actually offshore. Still, the quality is rated as marginal, so it’s not as clean as Saturday.
After that, we drop off again. Monday and Tuesday the 7th and 8th have size but messy conditions or only fair wind, and by the 9th and 10th of September, the swell is dropping and the wind is swinging cross-shore again. The last few days of the outlook, the 11th, see the swell fade right out to 2-3ft, though with clean offshore winds – lovely to look at but nothing to ride.
So, bottom line: the first week is a wash. The real surf to plan for is Saturday the 5th of September, glassy with 8ft west groundswell. That’s the one.
Rusty.
