The Lowdown
Alright, Rusty here, let’s talk about Porsmilin. The next couple of weeks are a tough stretch for us. The first week is pretty much a write-off, with tiny, weak, and often wind-affected waves. We've got a real quiet patch from now until the 7th of August where the best you can hope for is a knee-high dribble, and the winds are mostly cross or onshore. It’s a proper flat spell, and you’re better off leaving the board in the car.
Things finally start to look a little more interesting on Saturday the 8th of August. The morning brings a glassy 3.3ft swell from the SSW with a short period of 7 seconds, so the wave energy is still pretty weak (135), but those glassy conditions will make it look clean. The afternoon bumps up to 4.3ft with the same SSW direction and a moderate energy reading (206). It's not going to be pumping, but it's the first real chance for a surfable wave. The water is about average for this time of year.
Sunday the 9th of August sees the biggest swell of the whole run, with 6.9ft from the SW and moderate energy (574). That’s getting into expert-only territory, and the period is a short 8 seconds, so it’ll be a bit of a messy, crumbly wave. The morning has a light cross-shore wind, but the afternoon goes cross-onshore, so don’t expect any quality.
After that little spike, it all falls apart again. From Monday the 10th right through to the end of the forecast on the 15th, we’re back to tiny, weak swell with mostly onshore or cross-onshore winds. There’s nothing else to get excited about.
The standout window is Saturday the 8th of August. If you can sneak out for a session, the glassy conditions on that small SSW swell will be the cleanest you’ll see all period. It won’t be big, but it’ll be your best bet.

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.
