The Lowdown
Alright, Rusty here. Let’s have a look at what’s on the cards for the local scene.
Straight up, this is a lean run. We’ve got a long stretch of mostly small, sloppy, or wind-affected surf ahead. The first real chance of something half-decent doesn’t even show until Monday morning the 7th of September, and even then it’s not a home run. The good news is, when the swell shows, the conditions aren’t a complete write-off.
Portwrinkle is the only break on offer, and it’s a tricky one. It’s a reef setup, which can handle a bit more direction than a beach, but it’s inconsistent and can get crowded. The water temp is about average for this time of year, so no surprises there.
Saturday the 5th starts tiny, with a 2ft WSW swell (136 combined energy) and clean early on, but it’s weak and short-period – not really worth getting wet for. Sunday the 6th is even smaller and choppy. Skip it.
The Monday morning (7th September) is our closest stand-out. We get a 3ft WSW swell with a long 13-second period (383 combined energy). That’s a solid groundswell pulse. The wind is WNW cross-off, so it’ll be clean. For Portwrinkle, a long-period swell from the WSW is a good match – it’ll wrap in nicely. It’s not huge, so it’s fine for most ability levels, but keep in mind the reef and the inconsistency. Crowds are often here, so expect company.
The rest of the first week is a mix of small, onshore junk and moderate cross-shore chop. Some afternoons clean up a little, but the energy is too low to excite.
The second week, from the 12th onwards, turns into a flat spell. Weekdays the 14th through the 17th offer swell heights barely ankle-high with combined energy in the single digits – essentially a washout. There is a very light, clean session on the 15th Tuesday morning, but with only ankle-high swell, you’d be bobbing rather than surfing.
The last couple of days (19th & 20th September) show a tiny, clean pulse with a very long period from the south (14-16 seconds), but the swell height is just knee-high. That’s a whisper, not a wave.
So, for the 16-day window, Monday morning 7th September at Portwrinkle is the only real shout. It’s not a classic, but it’s the best of a quiet spell.
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.
