The Lowdown

Right, mate, Rusty here. Let’s have a look at what’s cookin’ for Porsmilin over the next couple of weeks.

Honestly, it’s a pretty flat and quiet stretch for a while. We’ve got a bit of a dry spell to kick things off. The first surf I can even talk about is Thursday the 6th of August, but even that is pretty average. We’ve got a small, weak 3ft swell rolling in from the WNW with a short period of 6 seconds, and the combined energy is a low 109. It’s surfable, but the conditions are very ordinary. The wind is cross-off, so it’s clean, but the wave size and quality are nothing to get excited about.

That really sets the tone for the whole first week. The next few days are tiny – we’re talking 1.0ft to 2ft swells from the west and northwest. There is a moment on Tuesday the 11th of August in the morning when the wind goes glassy, which is a beautiful thing to see, but the swell is still only 2ft with a period around 8 seconds. It’s pretty, but it’s not giving you much to ride.

We start to see a small pulse of energy around Wednesday the 12th of August with the swell size creeping up to 3ft, but the wave comment still says “very ordinary conditions.” The combined energy finally climbs back over 100, which is something, but it’s not exactly firing.

The real change, and the only standout in this whole 16-day window, happens a week and a half away, on Monday the 17th of August. We get a solid jump in swell size. Monday morning sees a 6ft swell from the west, pushing the combined energy to a moderate 381. But here’s the catch – it’s coming from a west-southwest direction, which is cross-on. That’s going to mess with the shape. By Monday afternoon, the swell jumps to 8ft with a combined energy of 1097, and a WSW wind that is directly onshore. That’s a lot of water moving around, but it’s going to be a messy, blown-out mess. This is expert-only territory, and honestly, with that onshore wind, it looks more like a day for the kite surfers to have a ball than a paddler.

Tuesday the 18th of August stays big with 8ft swell, but the wind shifts to the WNW at 19 mph, which is cross-off. It’s still a lumpy, powerful ocean. The wave comment for the afternoon is “marginal,” but that fresh cross-off wind might clean up some of the chop.

After that, it starts to back off again, with 5ft to 6ft swell through the rest of the run, but the conditions are often marked as “poor” or “marginal.” The wind is a mixed bag.

So, the long and short of it: there’s not a single session in this 16-day window that I’d call a true standout for paddle surfing. The early part is too small, and the bigger stuff in the second week is blown out or messy. If you’re desperate, keep an eye on Tuesday the 18th of August when the cross-off wind might give you some workable, powerful 8ft to 8ft waves, but it’s a gamble.

Stay patient, mates.

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.
