The Lowdown
Alright folks, it's Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a proper paddle. I've scanned the charts for the next sixteen days, and honestly, there's a long, quiet gap staring us right in the face.
From now, all the way through September 10th, it's a bit of a write-off. We're looking at a solid ten, eleven days of poor conditions. Nothing's breaking clean, the wind's mostly a mess, and the swell's either tiny or just too chopped up to enjoy. You'll see some size bumping up around August 31st, with a 5ft SW groundswell and a 10-second period, but the 30 km/h cross-off wind is just going to make it a lumpy, tricky session at Portwrinkle. There's a bit of moderate wave energy in the water, around 452, but it's just not coming together.
Then, after a real flat spell in the middle of the first week of September, we finally get a whisper of something. September 8th's Tuesday afternoon brings a 6ft SW groundswell, 10-second period, and a clean cross-off breeze. The energy reading is a solid 627, so there's some decent push. It's only marked as "marginal," but after so much flatness, that's about as good as it's going to get. The water temp's about average for the time of year, so no surprises there.
Looking way down the line, into the second week, the real standout is shaping up for Friday, September 11th. A solid 7ft W groundswell, with a long 10-second period, rolls in under clear skies and a clean cross-off breeze from the NW at 20 km/h. The combined energy jumps to a strong 1243. That's a proper session, but a word of warning: 7ft is expert territory, especially on a reef setup like Portwrinkle. The swell direction is a good match for the spot's optimum SW angle, so it could have some real shape. Just be aware, September 12th's 6ft to 7ft is a lot more mixed up with onshore breezes, so that Friday the 11th is your golden ticket – though at this range, keep an eye on the forecast. Crowds are possible at Portwrinkle on a day like that.
So, for now, give the water a miss for a good ten days. If you absolutely have to get wet, the later part of the second week holds some promise, but don't plan the trip around it just yet.
Rusty.

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 Portwrinkle 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.
