The Lowdown
Alright, Rusty here. Let’s have a look at what’s shaping up for us.
Honestly, this is a tough run to write about. We’re looking at a solid week and a half of nothing worth paddling out for. From now right through to September 12th, it’s mostly cross-onshore junk, short-period slop, and lumpy conditions. You’ll see a few cleaner moments on the 4th and 7th, but the wave heights are tiny and the energy is weak – mostly under 100 (weak). There’s nothing here to get excited about.
The first real glimmer of hope doesn’t come until Sunday, September 13th. Even then, it’s just a single morning window.
The Only Real Standout:
Portwrinkle on Sunday morning, September 13th. We’ve got a 5ft swell coming from the W, which is a solid size – maybe a bit much for the absolute beginners, but it’s not out of control. The real magic here is the wind: glassy. Glassy! That’s a massive positive, meaning clean, smooth waves with no chop. The combined swell energy reads 392 (moderate), and while the period is 8 seconds, the glassy conditions will make it feel way better than the numbers suggest. The swell direction from the W is a good match for this reef, which is fairly exposed to SW. Just keep in mind, Portwrinkle can be inconsistent and crowds are possible here, so get out early. This is the one morning to circle on the calendar.
Apart from that, the rest of the second week is a bust. The 16th and 17th show some cleaner winds, but the swell is tiny – 1ft to 3ft – and the energy is mostly weak (37 to 130). Surfable but ordinary.
Bottom line: if you’ve got a free Sunday morning on the 13th, Portwrinkle might just deliver a few clean ones. Otherwise, it’s a waiting game. Forecasts can always shift, so don’t write the whole fortnight off yet.
Rusty.

Information about the Portwrinkle Surf forecast
The above surf forecast table for Portwrinkle provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Portwrinkle can be found by selecting the local surf guide option on the grey menu. Our Portwrinkle 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 (Portwrinkle) 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 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.
