The Lowdown

Alright, this is Rusty, and I’m taking a look at the local surf scene for the next couple of weeks. Let’s get straight into it, 'cause I’ll be honest, it’s a pretty grim stretch ahead.

The overall pattern is a long, flat, and wind-affected mess. We’ve got a massive gap of nothing worth paddling out for from now all the way through to the second week of August. The first real chance of anything even remotely surfable doesn’t show up until the afternoon of Thursday, 13 August, and even that’s a marginal call.

For the first week and a half, it’s a desert. The wind is mostly cross or cross-off, but the swell is tiny – often under 2ft – and the period is short, around 8 seconds. The combined swell energy is weak, with values between 8 and 83. There’s no power, no push, and the conditions are consistently described as "poor surf conditions." It’s the kind of flat spell that makes you check the forecast twice to see if you missed something.

The only blip of activity comes at Porsmilin, a sandbar break that’s fairly consistent. On Thursday, 13 August, the afternoon shows a little pulse: swell height gets to 3ft from the WNW with a period of 10 seconds. The wind is a gentle cross-off from the NNW, which keeps the surface clean. The combined energy bumps up to 135, which is moderate but at least in the conversation. The swell direction is SW, which is what this spot likes. Still, the waves are described as "surfable but very ordinary" – it’s a small, weak wave. It’s not a standout, it’s just the only thing on the board.

Friday, 14 August, has a similar setup in the morning: 3ft from the WNW, 9-second period, cross-off wind from the SE, but the wave comment is "poor surf conditions." The afternoon sees a slightly bigger 3ft from the WNW, period 10 seconds, and a clean cross-off from the E, with energy at 174. But again, the rating is poor. The swell is too weak and short-period to really offer any quality.

There is no standout session in this entire 16-day window. The best you’ll get is a small, weak, ordinary wave on Thursday or Friday of the second week. If you’re desperate, you might get a longboard out for a few ankle-biters, but don’t expect any real juice. The water temp is 65°F, which is about normal for the time of year, so at least you won’t freeze waiting for nothing.

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.
