The Lowdown

Alright folks, it’s Rusty here. Let’s have a look at what’s on offer for Porsmilin over the next couple of weeks. I’ll tell you straight up, it’s a pretty grim run for the most part. We’ve got a long dry spell at the start, with no real surfing to speak of for the first week and a half. The first proper chance you’ll get doesn’t roll around until Thursday the 3rd of September, and even then, it’s nothing to write home about.

The water temp is sitting at 64°, which is just about bang on average for this time of year, so nothing unusual there.

Now, let’s break it down. From Monday the 24th of August all the way through to Wednesday the 2nd of September, it’s pretty much a write-off. The swell is either tiny, onshore, or both, with a lot of poor surf conditions flagged. You’ll see some energy building around the 27th and 28th, with combined swell energy hitting the 370 to 573 mark (moderate wave energy), but the wind is a mess – onshore or cross-onshore and gusty, making it lumpy and choppy. Not worth paddling out for.

The real standout, if you can call it that, is on Thursday the 3rd of September. The morning session sees a light offshore wind from the north, blowing at 9 mph, hitting the beach clean. The swell is small at 4 ft, coming from the WNW with a period of 8 seconds, pushing combined energy of 176 (weak to moderate). The waves are described as surfable but very ordinary. It’s the only window in the whole 16 days that looks even half decent. If you’re desperate, paddle out then, but don’t expect any barrels.

After that, Friday the 4th and Saturday the 5th see a slight bump in size, but the wind swings back onshore and cross-onshore, with moderate chop. The swell is mostly 4 ft to 5 ft, but the quality is poor.

Then, things get interesting, but not in a good way. On Tuesday the 8th of September, a massive pulse of swell hits. The morning sees a 15 ft swell from the west with a very long period of 18 seconds – that’s some serious groundswell energy. Combined energy is a whopping 11395 (very strong wave energy). The problem is the wind is a fresh cross-onshore, making it lumpy. By the afternoon, the swell is still 12 ft from the WNW with a period of 15 seconds, and the wind lightens up, but the forecast is clear: the swell is predicted to be too big for this break. This is expert-only territory, and even then, with the wind, it’s a mission. The long period also means it’ll be breaking straight at this beach break, so it’s not ideal. Honestly, that setup looks more interesting for kite surfing than paddle surfing.

So, the bottom line: if you want a surf, the only shot is Thursday morning, the 3rd of September. That’s your best, and really only, option. The rest of the 16 days is a long, frustrating wait.

Stay safe, and keep your eyes on the charts.

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.
