The Lowdown
Alright, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
Honestly, folks, it’s a bit of a tough stretch. We’ve got a solid run of small, weak swells and a whole lot of nothing to get excited about for the first ten days or so. The waves are just not showing up, and when they do, the conditions are making it hard to get excited. The water temp is sitting at 64°, which is bang on average for the time of year, so at least a dip won't be a shock.
We kick off with a few pulses of swell around the 3 ft mark from the WNW, but the wind is a mess. Wednesday the 29th has a light cross-onshore breeze which just ruins the shape, and the combined energy is only 104. It's a "poor surf conditions" call, and I'm not arguing. Thursday the 30th cleans up a bit in the afternoon as the wind goes cross-off, but we're still talking about 3 ft, weak stuff. This flat patch just drags on. Friday the 31st through to Sunday the 4th of August is all 2 ft or less, with some offshore winds that keep the surface clean, but there's just no power in the water. The combined energy readings are all below 100, some as low as 17. It's a long, quiet period.
We do get a bit of a window on the 5th of August – a long period 12-second groundswell from the west, but it's only 0.7 ft. That's barely a ripple. The offshore wind is fresh, but there's nothing to ride. The energy is sitting at 25. Nothing to see here.
Then, finally, on the 11th of August, we see a little spike. The morning of Tuesday the 11th brings a 4 ft swell from the NW, with a short period of 6 seconds and combined energy of 127 – that's moderate energy. The wind is light and cross-off, so it’ll be clean. The notes say "surfable waves but very ordinary conditions," which is about right. It’s a small, short-period swell, not the best shape. The afternoon pushes up to 4 ft and 171 energy, but the wind picks up and goes cross-off again. It’s the best we’ll see, but it’s not a standout by any stretch.
For the rest of the second week, from the 12th onwards, it's back to small, clean but weak conditions. The swell dips back under 3 ft, with light to moderate cross-off winds. It’s frustrating, because the conditions are often clean, but the swell just isn't there.
There's no real standout break here. The only spot in the mix is Porsmilin, a sandbar setup. It’s fairly consistent, but that’s not saying much right now. The optimum swell direction is from the SW, and we're getting waves from the WNW and NW, so it's not a perfect match. The best bet is the morning of the 11th of August, with the 4 ft NW swell and light cross-off wind. It’s not the day you call in sick for, but it’s the only thing on the calendar that’s not a total write-off. Crowds are noted as "sometimes" here, so you might see a few others with the same idea.
This is a real dry spell. It’s one of those times where you just have to wait for the next weather system to stir things up. Don't hold your breath.
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.
