The Lowdown
Alright, Rusty here with the lowdown for Porsmilin.
Let’s be honest, the first ten days or so are pretty grim. From Sunday, August 2nd, right through to the morning of Thursday, August 13th, it’s mostly a bust. You’ve got small, weak swell with the wind coming sideways or onshore most of the time, making a real mess of things. Wave energy is barely registering, sitting in the double digits most days. There’s a brief moment on Tuesday the 4th with a 4ft swell from the WSW, but it’s got a short 7-second period and a strong 15 mph cross-on wind – choppy and tough.
On Thursday morning the 6th, we get one “surfable but ordinary” call – a 4ft swell from the WNW with a light 9 mph cross-off wind, so it’s clean. But the energy is weak and the period is short. It’s a blink-and-you’ll-miss-it window.
Then things go quiet again until we hit the real standout: the morning of Friday, August 14th. That morning is looking like the best of the forecast. You’ve got a solid 7ft swell from the west, with an 8-second period, and the wind is a light 9 mph from the NE – cross-off and clean. The wave energy is strong at 1005. The west swell direction matches the spot’s ideal SW. It’s a decent-sized wave, so it’s more for the crew with some experience. And given it’s the best day in a while, expect the lineup to have a few more heads than usual.
The afternoon of the 14th still offers a 6ft swell with a clean offshore wind from the north at 18 mph, though it’s a bit breezier. The energy is strong at 886. A good backup. Saturday morning the 15th stays clean with a 6ft swell and lighter wind, but the energy drops to 450 and the conditions are called more marginal – a decent follow-up but not the peak.
Looking into the second week, Monday morning the 17th brings a 7ft swell from the WNW with a 10-second period and a clean cross-off NW wind at 12 mph. Energy is a strong 788. That’s another big one for the experts, though the direction is a bit more north than the ideal.
Water temps are sitting around average for this time of year – no big anomalies to talk about.
Rusty out.

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.
