The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Porsmilin over the next couple of weeks.

Honestly, it’s a pretty grim start. We’re looking at a long, dry stretch with no real surf on offer. From Wednesday the 29th of July right through to the morning of Friday the 7th of August, there’s just nothing worth paddling out for. The swell is tiny, the period is short, and the energy is weak as a kitten – barely reaching 100 (combined energy of all swells directed here). Winds are mostly cross or cross-off, but with such small waves it’s a bust. You’d be better off taking the dog for a walk.

Then, finally, a glimmer. Friday the 7th of August morning is where it’s at. The wind goes dead calm – glassy, 0 mph – and that’s a massive positive. A solid 7ft swell from the WSW rolls in, with a period of 8 seconds. The combined energy jumps to 521 (moderate wave energy), which is a real kick. This is the standout of the whole outlook. The swell is a bit on the bigger side for beginners, but for the intermediate crew, this is going to be a fun morning with clean, glassy conditions. The optimum swell direction is SW, and we’re getting WSW, so close enough. It’s a sandbar break that’s fairly consistent, so expect some waves. Crowds are possible here, so get in early.

The afternoon of Friday the 7th holds some size at 6ft, but the wind swings to a cross-off from the NW 12 mph, and while it’s clean, the energy is a whopping 1120 (moderate wave energy), which means it’s powerful but might be a bit bumpy with that breeze. The morning is still the pick.

Saturday the 8th of August still has some life, with a 5ft swell in the morning from the WNW, and light cross-off winds from the NE 6 mph keeping things clean. The energy is 482 (moderate wave energy). It’s a solid option if you miss Friday.

Sunday the 9th drops off a little, with 4ft and a period of 9 seconds, but it’s clean and the energy is 209 (moderate wave energy). It’s surfable, but nothing special.

After that, it fades out again. Monday the 10th through to the end of the outlook on Thursday the 13th of August sees the swell shrink back to 1ft to 4ft, with weak energy readings all in the double digits (between 24 and 195). The wind is offshore or cross-off, but the waves just aren’t there. It’s a quiet end to the run.

So, to sum it up: the first week is a write-off. The only real window is from Friday the 7th of August morning through to Sunday the 9th of August. If you’re keen, lock in Friday morning – that’s the best of the best, with glassy conditions and a solid 7ft WSW swell. The water temp is about 65°F, which is normal for this time of year, so no surprises there.

Rusty, signing off.

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.
