The Lowdown
Alright folks, Rusty here. Let’s break down what’s cookin’ for the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell to sit through. The first few days are a write-off – weak, short-period windswell and onshore crud. From Tuesday the 1st right through to Friday the 4th, it’s just messy, choppy, and not worth paddling out for. You’re better off waxing your board or checking the tide pools.
The first real glimmer of hope shows up on Saturday morning, September 5th. We’ve got a solid 5ft groundswell rolling in from the WNW with a long 12-second period (combined energy of 626). That’s proper energy, and the wind is a light cross-offshore from the ENE – clean lines. The afternoon stays clean but the swell drops off a touch. This is your first real window, and it’s a beauty.
Sunday the 6th is a dud again, so don’t get your hopes up.
Then, the standout of the whole outlook hits on Monday, September 7th. Porsmilin is the only break on the menu, and it’s going to be firing. Morning session sees a 7ft WNW groundswell with an 11-second period – that’s solid, powerful stuff – and a light cross-offshore wind from the NNW keeping it glassy. The combined energy is a whopping 987, so you’ll feel the push. This is expert-level size, so if you’re not confident, sit this one out. The afternoon stays clean but the swell drops to 6ft, still a great session.
After that, the surf gets a bit mixed. Tuesday the 8th and Wednesday the 9th have some size but the wind jacks around, making it choppy or cross-shore. Not terrible, but not the clean perfection of Monday.
We hit another dry patch from Thursday the 10th through to Sunday the 13th. Tiny, weak, and mostly onshore. Just a lot of nothing.
Hang in there, because Monday, September 14th is your second big highlight. Morning and afternoon both show 5ft and 5ft WNW groundswell with a long 12-second period, combined energy of 919. The wind is light and cross-offshore from the E and then NNW – clean, lined-up waves. This one’s a bit more manageable than the 7th, but still a strong groundswell. Another beauty.
The last couple of days, Tuesday the 15th and Wednesday the 16th, have some fun clean waves in the 3ft to 4ft range, with offshore winds on Wednesday afternoon. Nice way to wrap up the forecast.
The water temp is sitting at 63°F, which is pretty normal for this time of year, only 0.5°F off the average. No need for a thick wetsuit, but a spring suit will be your friend.
Signing off, 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.
