The Lowdown
Alright, Rusty here. Let’s have a look at what’s shaking for Porsmilin over the next couple of weeks. This sandbar is fairly exposed to the SW, and we’ve got a bit of a slow start, but there’s a couple of windows that’ll get the blood pumping if you time it right.
Right off the bat, the first few days are pretty ordinary. That Thursday and Friday (3rd and 4th) are a write-off with onshore winds and weak, short-period swell. You’ll be fighting a cross-onshore chop for no reward. Not worth wetting a wetsuit.
Saturday, 5th September is where it starts getting interesting. A solid pulse of groundswell rolls in from the WNW, pushing 7 ft with a long 13-second period. The combined energy is pumping strong (1308), and while the morning has a bit of a cross-shore bump, by Saturday afternoon it cleans right up with a light offshore from the NNW. That’s your best session of the window—clean, lined-up waves with proper push. The water temp is sitting around 63°, which is pretty normal for this time of year, nothing wild there. Just be aware, with that quality and a fairly consistent break, you might run into a few other locals; it gets busy sometimes.
After that, Sunday (6th) drops right off, so don’t bother.
Then we’ve got a cheeky run from Monday (7th) through Wednesday (9th). The morning of Monday 7th shows 8 ft W swell (12 seconds) and big energy (1610), but it’s accompanied by a cross-shore wind that’ll leave a bit of chop on the face. It’s got power for sure, but you’ll need to pick your tides and spots to find the clean ones. Wednesday morning, 9th September, brings it back nicely—6 ft from the WNW, clean with a light offshore from the north. That’s a solid, fun session for an intermediate surfer.
From the 10th through the 13th, it’s a mixed bag. Wind gets strong and messy, swell fades. The 12th and 13th see offshore winds from the NNE and NE, but the swell is only 3 ft. Surfable, ordinary—just keep the board on the car if you’re not desperate.
Tuesday, 15th September is your other standout. A solid 5 ft from the WNW with an 11-second period and light cross-offshore breeze from the NE means clean lines and good shape. The energy is moderate but punchy (469). It’s a week and a half out, so not as solid a lock as the 5th, but definitely one to keep an eye on.
After that, the swell fades into the small stuff. A glassy morning on Wednesday 16th with 2 ft is about it—pretty, but tiny.
Overall, if you’re picking one day, make it Saturday 5th September afternoon. Clean, solid, long-period groundswell. Tuesday 15th morning is your long-range hopeful, but a close second.
Stay wet.

Information about the Porsmilin Surf forecast
The above surf forecast table for Porsmilin provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Porsmilin can be found by selecting the local surf guide option on the grey menu. Our Porsmilin surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Porsmilin) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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.
