The Lowdown
Alright, Rusty here. Let’s break down what’s coming for the next couple weeks.
The week starts quiet, but the real action kicks off this Saturday. Porsmilin is the spot to be. Saturday morning we’ve got a solid 6.9ft swell from the WNW, and the wind is a clean cross-off out of the ENE at just 3 mph. That’s glassy, clean, and excellent for experienced surfers. The combined energy is pumping at (1488). Water temp is 63.3°, right about average for this time of year.
Saturday afternoon stays clean with a 6.2ft WNW swell and light NW cross-off wind – still very good. Sunday is a write-off with messy onshore wind and weak energy.
We get a few marginal days midweek, but nothing worth rushing out for.
The next real standout is Saturday the 12th. Porsmilin gets a 5.2ft WNW swell, light easterly cross-off wind at 3 mph, and a long 12-second period. That’s clean lined-up groundswell with moderate energy (701). Great for intermediates.
Then on Tuesday the 15th, a punchy 6.9ft WNW groundswell rolls in with a gentle offshore from the NE at 9 mph. Clean conditions, solid energy (736) – this one is for the experienced crew only.
After that, the second week fades into smaller, cleaner but unremarkable surf. By the 19th, it’s back to weak, onshore dribble.
Best bets: Saturday September 5th morning and Saturday September 12th afternoon. Don’t miss ’em.

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.
