The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for Porsmilin over the next couple of weeks.
Alright, straight up, the first few days are a bit of a mixed bag. We’ve got some swell around, but the winds are going to mess with it. Wednesday the 9th is the pick of the early stuff. We get a clean, cross-off breeze with a 6ft NW swell. The wave energy is moderate (689), but that cross-off wind will keep the face of the wave tidy. It’s a decent start for an intermediate surfer. The water temp is about average for this time of year.
Thursday the 10th is a write-off, with onshore winds and small, weak surf. Friday and Saturday the 11th and 12th stay small and ordinary, though Saturday morning looks glassy with a light 3ft swell from the west. You might get a few fun ones if you’re desperate for a paddle.
Sunday the 13th sees an increase in swell height to 6ft with a moderate energy level (714) and a long, 12-second period from the WNW. This is a proper groundswell, but the cross-on wind is going to put a chop on it. It’s more of a challenge than a pleasure.
After that, the surf goes quiet again. Monday the 14th and Tuesday the 15th are small and inconsistent. We’ve got a gap of a few days here with nothing to write home about. The energy drops right off.
Now, here’s where things get interesting. Looking further ahead, Saturday the 19th is a standout. The morning session sees a 6ft WNW swell, with a very decent 11-second period and a light offshore from the NE. That’s clean, lined-up waves with moderate energy (620). This is the best of the first week, no doubt.
But the real gem is Wednesday the 23rd. We’ve got an offshore NNE breeze in the morning, a 15-second period swell from the WNW at 4ft. The combined energy is strong (758). That is a very long-period groundswell, and it’s going to bend beautifully around Porsmilin. This is a reef/point-style setup in spirit, and with those periods, the shape will be unreal. It’s a long-range call, so don’t bet the farm on it, but if this holds, it will be the session of the outlook. Thursday the 24th also looks good with glassy conditions and a 3ft WNW swell.
Keep an eye on the 23rd, folks. That’s the one to circle.
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.

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.
