Porsmilin Surf Forecast and Surf Report

Alright folks, Rusty here. Let's get straight into it for Porsmilin.

The next two weeks-plus are a real mixed bag, a bit of a frustrating stretch for sure. We're looking at a decent pulse of swell early on, but the winds are going to make things messy before they clean up. There's a proper window of quality in there if you play it smart, but the rest of the forecast is mostly a write-off for good surfing. We do have to sit through a few proper flat days later on, so manage your expectations.

It all kicks off on Sunday the 30th and to be honest, it's not worth getting wet for. There's some energy in the water with a 5ft swell, but the wind is howling from the SW at 15.5 mph, blowing straight cross-onshore. It's going to be a choppy, blown-out mess. The combined wave energy is at 419, which is moderate, but it won't matter because the surface is going to be terrible. That afternoon it gets even worse – the wind is forecast to push up to 25 mph with a squall risk, and the period drops to just 7 seconds. The wave energy rises to 482, but this is a full-on stormy, onshore washing machine. Forget it.

Monday the 31st is more interesting, but still not perfect. The swell is up to 8ft and the period jumps to 10 seconds, and the wind swings around to the NW, which is cross-offshore here. The combined energy jumps way up to 1437, so there's some serious power in the water. The problem is the comment flags "marginal surf forecast or questionable tide conditions." It’s going to be big and clean, but might not have the right shape. This is for experienced surfers only; that size is too much for beginners. The afternoon stays similar with the energy still high at 1155, but it's still only a two or three out of ten for me.

Tuesday the 1st of September sees the swell drop quickly, down to around 4ft for the morning. The wind turns onshore from the SSW at just 6 mph, which is light, but it's still onshore. The energy has dropped right off to 295. It's looking pretty average and weak. The afternoon is even worse, with the swell dropping further to 3ft and the wind going cross-onshore. Not a day to get excited about.

From Wednesday the 2nd through to Thursday the 3rd, the surf goes dormant. The swell is tiny, ranges between 2ft and 4.5ft, with short 8-second periods, and the SW wind is cross-onshore and clocking in at 12.5 mph. The energy is weak, around 93 to 450. This is just poor, choppy, dribbly surf. A full two-day gap where the best option is to find another hobby.

Just when you're about to give up, Friday the 4th of September looks like a serious standout. The swell fills in properly to around 7.5ft in the morning, and the period has stretched out to a long 12 seconds. This is proper groundswell, and the wind has swung to the NW at 9.5 mph, which is a clean cross-off. The energy is a very strong 1457, and the model is saying "excellent surf conditions for experienced surfers." This has the potential to be really, really good. Porsmilin is a sandbar, and a long-period WNW swell like this can be a touch straight, but with that cross-off wind, it could be holding a nice shape. This will be big, powerful and for experienced surfers only. The afternoon keeps the pace up, energy jumps to a massive 2866, but the wind picks up a touch to 12.5 mph. It's still a top pick for the period.

Saturday the 5th of September is your second, and arguably the best, call of the stretch. The morning is where it's at. The swell is still a solid 7ft with a 12-second period, and the wind goes offshore from the NNE at a light 6 mph. The energy is still cranking at 1202. The record says "expect very good surf conditions." This is the one. Glassy, clean, powerful, long-period waves. It’s going to be all-time if the sandbar is holding. The crowd is listed as "sometimes," so you might get a few out, but it will be worth it. The afternoon backs off a little in size to around 6ft as the wind swings more to the north. Still good, but the morning is the session to target.

After that, it's a slow and sad fade. Sunday the 6th of September the swell drops back to under 3ft, the wind goes cross-shore and the energy just dies. Monday and Tuesday are similar small and unexciting, and by the 10th and 11th of September it looks tiny, with energy readings in double digits.

There's a brief flicker of life on Saturday the 12th, with some shoulder-high leftovers and a bit more energy, but then it's pretty flat and ordinary right through the end of the forecast on Monday the 14th. There will be a frustratingly flat end to the window.

So, to be straight with you: Friday the 4th and
