Porsmilin Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a proper look at what Porsmilin’s got cookin’ for us over the next couple of weeks. It’s a bit of a slow burner, so hang tight. The good news is, there’s a clear standout window that’s worth planning for.

We start off with a flat spell. The first couple of days are a write-off. Wednesday the 2nd and Thursday the 3rd are dominated by that strong SW wind, making a mess of things—pure onshore junk, with swell energy weak (241) and choppy as all hell. Friday the 4th morning is still rubbish, but keep an eye on the afternoon. The wind swings around to a light NNW cross-off, and the swell starts to clean up. We’re looking at 6ft of WNW groundswell with a 9-second period, and you can feel the energy building to (513). It’s the first sign of life.

Now, Saturday the 5th. This is the highlight of the whole outlook. Saturday morning is the real gem. Clear skies, a light ENE breeze keeping it glassy—a proper cross-off wind. Swell is 6ft from the WNW, with a period hitting 13 seconds, so plenty of grunt behind it. The combined energy is pumping at (1159), which is a nice, strong, clean pulse. Porsmilin is a sandbar setup, fairly exposed to this SW optimum, and it’s gonna be working beautifully. This is the one to get wet for. The afternoon holds up too, with similar 6ft swell and light NNW winds, still clean.

Sunday the 6th drops right back off. Swell plummets to under 3ft, and the wind turns onshore again. Not worth paddling out.

The following week gets a bit rowdy. Monday the 7th morning sees a jump to 7ft from the west with a 12-second period and energy of (1355), so there’s plenty of water moving. But the wind is cross-shore and lumpy, making it messy. That size is pushing past beginner territory, and the conditions are marginal. Tuesday the 8th is similar—big but rough, with fresh cross-shore winds creating a lumpy cross-chop. This is more of a kite-surfing setup than a clean paddle session.

We get a bit of a lull from Wednesday the 9th through the weekend of the 13th. Mostly small, weak swell with onshore or cross-shore winds. Not much to get excited about—just a few knee-high dribblers.

Then, week two rolls around. Monday the 14th shows a new pulse coming in. 5ft from the WNW, period up to 12 seconds, energy around (650). Winds are light, but the conditions are still a bit marginal. Tuesday the 15th and Wednesday the 16th are where it gets interesting again. Tuesday afternoon has 4ft from the WNW with an 11-second period, but the wind is a light NW cross-off, keeping things clean. The energy is moderate (390) but the quality is there. Wednesday morning the 16th looks even better—a glassy offshore NNE breeze at just 3 mph, with 3ft groundswell. That’s proper clean conditions for a sneaky session. After that, it fades out to tiny surf for the rest of the period.

Water temp is sitting around 63°, which is about average for the start of September here. No crazy anomalies, just your standard autumn cool-down.

So, if you’re picking your moment, Saturday the 5th is your day. Clear, glassy, clean groundswell in the chest-to-head-high range. That’s the standout. The second-week window on Tuesday the 15th and Wednesday the 16th is worth a look for a quieter, cleaner session, but it’s smaller and less certain this far out. The rest is either flat, blown out, or too big and messy for a good paddle.

Stay stoked, and I’ll see you out there.
