The Lowdown

Right, let’s have a look at what’s on offer for the next couple of weeks. It’s a slow burn to start, with the first few days looking pretty grim. Onshore winds and small, weak swell through Wednesday the 2nd, Thursday, and Friday mean you’re better off doing something else. But if you can hold out, the weekend delivers.

The real standout is the morning of Saturday the 5th. We’ve got a clean 6ft swell out of the west-northwest, with a long period of 13 seconds—that’s proper groundswell. The wind is light offshore, so you’re looking at some real clean, lined-up waves. The energy is strong, coming in at 1042, and it’ll have some punch. This is the best of the whole run, no doubt. The afternoon is still decent with 6ft and a 12-second period, but the morning is where it’s at. Just a heads up, with that long period, it can straighten out a bit on a beach break, but this sandbar setup should handle it fine.

Then Sunday the 6th drops off a cliff. The swell backs right down to 3ft, the wind turns onshore, and we’re back to poor conditions. It’s a real bummer after that high.

But don’t get too down, because Monday the 7th morning is another big one for the experienced surfers. We’ve got a solid 7ft swell from the west with a 13-second period, light offshore wind, and combined energy of 1372. This is serious stuff. Powerful, clean groundswell. This is only for the guys who know what they’re doing—7ft with that much energy is no joke. The afternoon gets a bit cross-onshore and messy, so stick to the early session.

After that, the forecast turns ugly. Strong winds and rain hit Tuesday the 8th and Wednesday the 9th, with the swell still around but the conditions getting chopped to bits. Not worth your time.

There’s a dry spell of a few days with poor conditions and small swell until Monday the 14th. That afternoon, things perk up. We’ve got 5ft from the west with a 9-second period, light offshore wind, and clean conditions. The energy is moderate at 372, but it’s a solid, surfable option after a bit of a lull. Nothing like the previous weekend, but a good session all the same.

The water temperature is sitting about average for this time of year, so no need to go overboard with the thick rubber.

Into the second week, it’s a bit of a mixed bag. Tuesday the 15th has some size, 6ft, but the wind is cross-onshore and it gets bumpy. Wednesday the 16th has a 6ft swell from the west with an 11-second period, but the winds are all over the place and it’s looking marginal. You could get lucky if you pick your moment, but it’s not a sure thing.

So, to wrap it up: Saturday the 5th morning is the absolute winner. Monday the 7th morning is the big one for the experienced crew. The rest of the window is mostly waiting or dealing with onshore junk.

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.
