The Lowdown
Alright, Rusty here, and I’m looking at the same 16-day picture for Porsmilin. Let’s call it like it is: the surf is mostly a bust.
There's no standout day in this entire forecast. The first week has some sizeable swell, but it’s almost always accompanied by wind that ruins the shape. Then, from the 23rd of August right through the end of the month, we hit a flat spell that barely produces a wave you can ride. A little pulse on the 30th brings the waves back to around 3ft but it's still just ordinary.
Saturday the 15th starts us off with a weak 4ft swell from the WNW. There's a moderate cross-offshore wind from the north, so the surface is clean, but the waves are weak and the energy is moderate (209). "Poor surf conditions" sums it up.
Sunday the 16th drops off fast. You're looking at waist-high waves at best in the morning, and by the afternoon it's ankle-slappers.
The one window that has some power is Thursday the 20th of August. The morning brings a 6ft WNW swell, and by the afternoon it peaks at 7ft with strong energy (1458). The serious catch? A 30 km/h west wind blows straight cross-shore, creating lumpy, ugly cross-chop. At 7ft, that’s big, expert-only territory, and with that chop, most guys are going to look at it and say it's better for a kite than a paddle board.
Friday the 21st is still big in the morning, with a 7ft WNW groundswell and a cleaner offshore wind from the NW. The wave energy is still strong (764). It’s a "marginal" call because of the tide, but for an experienced surfer who knows the spot, this is the most promising session of the whole run.
Then the taps turn off. From Sunday the 23rd of August to Saturday the 30th, it’s just flat. Swell heights stay below 2ft, the wave energy is pitiful, and there’s nothing to ride. A long-period groundswell from the SW on the 25th is less than half a foot – a total tease.
Water temp's sitting at 18°, which is pretty normal for this time of year.
So, Porsmilin is having a rough patch. There's a short window on the 20th and 21st for the experts, but for everyone else? It’s a waiting game.

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.
