The Lowdown
Alright, folks, Rusty here. Let's break down what's on the cards for Porsmilin for the next couple of weeks. Gotta be honest, it's a bit of a slow start, but there's a light at the end of the tunnel.
The water is sitting at about 64°F, which is pretty normal for this time of year.
The first week is a tough one. We kick off on Saturday the 22nd with tiny 2ft waves from the west, and while the wind is offshore and clean, the swell energy is weak (94). It's just not enough. Sunday the 23rd and Monday the 24th are similar – small, weak swells, although Monday afternoon turns glassy with a light easterly breeze. Still, it's only 1ft. Tuesday the 25th sees a bit more energy (112), but the wind swings onshore, messing up the surface. Wednesday the 26th has a short-period 3ft swell, but again, onshore wind.
Then things get stormy. Thursday the 27th and into the weekend, a pulse of messy, wind-whipped swell arrives. Friday the 28th is the worst of it – 8ft of short-period, choppy slop from the west, with a strong cross-onshore breeze. The energy is high (829), but it's a complete mess for a surfboard. That kind of power and wind is better suited for the kite crowd. That lumpy, choppy look sticks around through the end of August.
Now, here's the good part. If you're patient, the first few days of September are where it's at. Monday the 31st of August, the swell starts to drop, and by the afternoon, it's glassy with 5ft waves from the west. The energy is moderate (279), but that glassy surface is a huge plus.
But the real standout is Friday the 4th of September. Mark this one down. We've got a solid 6ft groundswell from the west-northwest with a long period of 13 seconds. The combined energy is massive at 1107, meaning it's got some serious power. The wind is light and cross-offshore, which should keep the surface clean. For a sandbar like Porsmilin, that long-period swell could really line up and offer some powerful, well-shaped waves. This is the best bet of the whole outlook.
The morning of Friday the 4th is also worth a look with 4ft from the same direction, just a bit less grunt. After that, the swell fades on Saturday the 5th and the wind turns against us, so the window is short.
So, to wrap it up: the next week is a write-off. We've got a stormy mess mid-week. Hold out for that glassy Monday afternoon, but the real score is the Friday the 4th of September with that long-period groundswell and clean conditions. It's a long way off, so keep an eye on it, but it's got real potential.
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.
