The Lowdown

Alright folks, Rusty here. Let’s break down what’s on the cards for Porsmilin over the next couple of weeks.

It’s a bit of a slow start, but there’s some real promise lurking further out if you’ve got the patience. The first few days are pretty lean, with only tiny, weak, and mostly messy waves. The swell energy is low, barely cracking 45 (combined energy 45) on Tuesday afternoon, and the wind is either onshore or just not helping enough. Wednesday the 12th and Thursday the 13th see a little more size but with cross-onshore winds, so it’s not going to be pretty. Friday the 14th morning is surfable but very ordinary with a 3ft swell from the west, period of 9 seconds, and light cross-offshore breeze – the kind of session you take just to get wet.

The first real standout comes on Saturday the 15th afternoon. The wind swings offshore from the north at 16 mph, with a 4ft swell from the northwest. Sure, the period is short at 7 seconds, but the clean offshore conditions will make it rideable. The energy is moderate (298). It’s not world-class, but it’s the best of the early stuff.

After that, we hit a real dry spell. From Sunday the 16th all the way through Wednesday the 19th, the surf is poor – small, weak, or just messy. There’s a bump in size on Tuesday the 18th with 6ft swells, but the cross-offshore wind is too strong at 16 mph, and the energy (364) just can’t overcome the chop. Expect a few days of nothing special.

Now, for the patient ones: Thursday the 20th morning is the absolute standout. The swell jumps to 10ft from the west-northwest with a long period of 12 seconds, giving it serious grunt – combined energy a massive 2743. The wind is glassy, just a slight air, making for excellent, clean conditions. This is a big, powerful groundswell, and it’s going to be a heavy one, so leave the foamboards at home – this is for experienced surfers only. The long period might make the sets a bit walled at Porsmilin’s sandbar, but with that southwest optimum swell direction, the shape should be there.

Friday the 21st morning is another good window, with 7ft from the west-northwest, period of 10 seconds, and a gentle offshore from the north-northeast at 9 mph. Energy is 1435 – strong and punchy. Again, it’s for the more experienced crew.

The second week gets a bit hit-and-miss. Saturday the 22nd morning has a clean 6ft, but it’s not as solid. By Sunday the 23rd, the wind turns onshore and the rain comes, so it’s a write-off. Monday the 24th morning sees a massive 12ft swell from the west, but even with a favorable wind, it’s just too big for this setup – the energy is 3503, and it’s likely going to be a washing machine. Not for paddle surfing.

Overall, the best bet is Thursday the 20th morning and Friday the 21st morning. Crowds are possible at Porsmilin, so get there early if you can. The water temperature is right around 65°F, which is pretty normal for this time of year, so no surprises there.

That’s the story from Porsmilin. Get your timing right.

A general guide to surfing at Porsmilin can be found by selecting the local surf guide option on the grey menu.

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.
