The Lowdown
Alright, folks, Rusty here again. Let’s break down what’s cooking at Porsmilin for the next couple of weeks.
First thing, the water’s sitting at 63°F, which is pretty much average for the time of year, nothing weird going on there.
The forecast is a bit of a rollercoaster. There are a couple of real gems, but you gotta work through some windy, choppy days to get to ’em. The first decent window hits on Monday afternoon, September 7th. The morning’s a bust with a cross-on wind and a 7ft W swell that’s got a lot of energy, but it’s messy. By the afternoon, it cleans up nicely. The wind goes light cross-offshore from the WNW, and we’ve got a clean 7ft W swell with a 13-second period. That’s a proper groundswell, and the energy is still strong. It’s clean and punchy – a solid session for the intermediate crew.
Now, the absolute standout. You want to circle Tuesday, September 15th. Tuesday morning starts off with glassy conditions – a slight air from the ENE, cross-offshore – and a 7ft WNW swell with a 12-second period. The energy is pumping. That’s the warm-up. Tuesday afternoon is where it’s at. The wind is light from the NW, cross-off, and the swell builds to 8ft from the WNW, still with a 12-second period, and the energy is even higher. This is excellent surf for experienced surfers. The waves will have power, shape, and the wind will keep ‘em clean. This is your best bet, no question.
Then we hit a rough patch. The rest of the second week is a write-off with strong onshore winds and big, lumpy conditions. The swell gets huge – over 11ft on the 17th – but with 25 mph winds, it’s just a mess. That’s kite surfing territory, not a paddle session.
But there’s hope. Monday, September 21st has another promising window. The morning brings a solid offshore breeze from the NNE at 15 mph, a 6ft NW swell with an 11-second period, and good energy. The wind is offshore, so it’ll be clean. It’s a bit smaller than the 15th, but it’s a solid option for a late-season session.
Crowd check: Porsmilin can get busy, so on those good days, expect some company.
So, to sum it up: Monday afternoon the 7th is a good start, but Tuesday the 15th is the real standout – keep that day free. The 21st is a solid backup.
Rusty.

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.
