The Lowdown
Alright folks, Rusty here. Let’s break down what’s coming for Porsmilin over the next couple of weeks.
Right off the bat, the start of the forecast period is a total washout. Wednesday through to Thursday afternoon, the wind is blowing onshore and the waves are a messy, blown-out 3ft to 4ft from the west. The energy is weak to moderate (111 to 216), and the period is short, so it’s just lumpy, surfable chop. Not worth paddling out for.
The first real hope shows up on Friday afternoon. The swell picks up to 6ft from the WNW, with a period of 9 seconds and a big jump in energy to 425 (moderate). The wind shifts to a cross-offshore breeze from the NW, which will clean things up. It’s still not perfect, but it’s a start.
The standout of the whole outlook is Saturday morning, the 5th of September. We’ve got 6ft of WNW groundswell rolling in with a 12-second period, and the combined energy hits a strong 943. The wind is light and cross-offshore from the ENE. That’s clean, lined-up, proper surf. This is the session to circle on the calendar. The water temp is 63°, which is about 0.5° cooler than normal for this time of year, so pretty average – a thin spring suit will do.
Sunday the 6th drops right back off. The swell fades to 3ft, and the wind turns onshore again. Another gap.
Monday the 7th brings another pulse of quality: 6ft from the west, a long 13-second period, and very strong energy (1012). The wind is cross-offshore from the NW. This is a big, clean groundswell. That long period will make the waves heave up nicely at Porsmilin’s sandbar, but expect longer lulls between sets. It’s a powerful, expert-friendly wave at that size.
Tuesday the 8th gets messy again with cross-onshore winds, and Wednesday the 9th has a strong NNW breeze going 22 mph. Even though the swell is 7ft from the west with decent energy (685), that wind is fresh and strong – it’ll be a battle. More of a kite-surfing day than a paddle-surfing one.
We get a bit of a break mid-week, then the next real window opens on Sunday the 13th of September. Morning brings 6ft from the WNW with an 8-second period. The wind is light offshore from the NNE, so the waves will be clean and glassy. Combined energy is 422 (moderate). It’s a fun, manageable size for intermediates, and the offshore wind is a major plus. This is a solid second option.
The following Monday the 14th has 5ft from the NW with a 10-second period and 450 energy, but the wind is light and variable, leaving a bit of a ripple on the surface. It’s surfable, but not as clean.
After that, the swell drops right off into the middle of the week – tiny stuff in the 1ft to 2ft range. Not worth the drive.
The final good window is on Wednesday the 16th of September. The afternoon picks up 4ft from the west with a long 12-second period and a NNE offshore breeze. The energy is 389 (moderate). It’s not huge, but it’s clean and lined up.
And Thursday the 17th holds similar: 4ft from the west, 11-second period, and offshore winds from the NE. The wind picks up to 19 mph in the afternoon, though, so get out early for the cleanest conditions.
Bottom line: Best bet is Saturday morning the 5th – that’s the one to chase. Monday the 7th is the big-swell alternate for the experts. And the 13th through the 17th offers a few more clean, smaller sessions if you miss the first window.
Rusty out.

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.
