The Lowdown
G’day, I’m Rusty, your local surf reporter, and I’ve got the lowdown on what’s shaping up for Porsmilin over the next couple of weeks. It’s a bit of a mixed bag, but there are a few windows where it’ll get real good. Don’t expect much early on; you’ll have to wait a bit for the quality to show.
The first few days here are pretty rough. Thursday the 3rd and Friday the 4th are all cross-onshore wind and choppy mess, with swell around 4ft to 5ft coming from the west. The combined wave energy is moderate (around 206 to 558), but the wind kills it. You won’t want to bother paddling out.
Then, things start to turn. Friday afternoon the 4th brings a shift: wind goes cross-offshore from the northwest, swell lifts to 6ft from the west-northwest at a clean 8-second period, and the energy is moderate (416). Surf improves, but the real standout kicks off Saturday morning the 5th. That’s your best bet. Early Saturday, we’ve got clear skies, a light breeze from the east-northeast, clean conditions, and a solid 7ft west-northwest swell with a long 13-second period. The combined energy is strong (1308). This is a groundswell, so the waves will have real punch and shape, and it’ll be a bit heavier—maybe too much for beginners. The offshore wind holds into the afternoon, with 6ft from the same direction and a 12-second period (energy at 896). If you can only pick one day, Saturday the 5th is the one. Water temp is about average for the time of year here, nothing weird.
Sunday the 6th drops off quick: swell fades to 3ft, wind turns cross-onshore, and it’s back to poor conditions. That lasts through Monday the 7th and Tuesday the 8th, where the swell picks up again—Tuesday afternoon hits 8ft from the west-northwest (energy at 1936)—but the wind is a messy cross-shore and cross-onshore, so it’s only for the hardcore, and even then it’s marginal.
Wednesday the 9th through Thursday the 10th stays average with poor surf. Friday the 11th offers a small improvement: clean conditions with light cross-offshore wind and 5ft from the west (energy 499), but nothing special.
Saturday the 12th morning rounds out the first week with a rare glassy session—dead calm wind, 3ft west swell, but the period is short (8 seconds) and energy is weak (145). It’s surfable but ordinary. Then we hit a real dry spell: from Saturday afternoon through to Tuesday the 15th, it’s mostly poor or onshore junk. The only bright spot is Tuesday morning the 15th, with a clean, cross-offshore light breeze, 4ft west-northwest swell, and a nice 12-second period (energy 481). That’s a decent little session for the patient surfer.
After that, the rest of the second week fades out with small, messy, or blown-out conditions, so it’s not worth getting excited about.
All in all, focus on Saturday the 5th of September for the best clean waves, and maybe Tuesday the 15th for a quieter, cleaner option.
Stay stoked.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Porsmilin may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
