The Lowdown

Alright folks, Rusty here with the outlook for Porsmilin.

The surf around here is a bit of a mixed bag over the next couple of weeks, with a few real highlights if you pick your days right. Water temp is sitting at about 63°, which is pretty much standard for this time of year – nothing unusual there.

The first real standout kicks off Saturday morning, September 5th. This is the pick of the whole run for me. We’ve got a solid 7ft groundswell rolling in from the WNW at a very long 13 seconds, and the combined energy is pumping at 1488 (moderate to strong). The wind is a light ENE breeze holding cross-off, keeping the sandbar clean. This is excellent for experienced surfers – it’s got size, it’s got power, and with that long period, expect proper lines. It’s a bit much for beginners mind you.

The afternoon on Saturday drops a touch to 6ft but still a nice 12-second period from the WNW, with light NW cross-off wind. Still very good, just not as punchy as the morning. Then Monday morning, September 7th, another solid pulse arrives: 7ft from the West, 13-second period and a combined energy of 1632 (strong). The wind is a cross-shore from the W. Conditions are a little on the choppy side though, so it’s a more challenging session for the experienced crew who don’t mind a bit of texture.

After that, things get pretty quiet and average for a few days right through to the end of the first week and into the start of the second. You get a clean 5ft on Tuesday morning, September 8th, with a cross-off NW breeze, which is a small window for a decent, clean wave. But honestly, there’s a big gap of mediocre-to-poor surf from then until we get to the next real good one.

Jumping ahead to Saturday morning, September 19th, that's the other standout. We’ve got a solid 7ft swell from the WNW, period stretching out to a long 11 seconds, with a combined energy reading of 1087 (moderate to strong). The wind is a moderate offshore from the NNE, which will keep the sandbar glassy. This is excellent, proper surf for the experienced crew. The crowds are likely around here, so be prepared for some company on the best peaks.

One thing to note: the very long-period swells we see on Saturday the 5th are going to break a bit straight at a sandbar setup like Porsmilin, but when it’s that clean and that size, it’s still going to be a hell of a lot of fun.

So, if you want the best, your windows are Saturday 5th morning and then Saturday 19th morning. The rest is a wait-and-see game.

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.
