The Lowdown
Alright folks, Rusty here with a look at what we've got coming out of Portwrinkle. Gotta be straight with you from the jump – it's a grim run for the next sixteen days, and there's no sugar-coating it. This is a blank period, plain and simple.
We start off with a tiny window on Friday morning, the 11th of September. The swell is a measly 3 ft from the WSW with a short, weak 10-second period, giving us weak wave energy (161). The wind is cross-off, which is the best we'll see, keeping things clean. The water is sitting at 64°, which is a touch warmer than normal. But the waves are just too weak and gutless to get excited about.
From there, the bottom falls out. From Saturday the 12th all the way through to Saturday the 26th of September, the scores are just a desert. The swell never breaks 3 ft, the period bounces around, but the conditions are consistently, frustratingly poor. We get long patches of cross-onshore and onshore wind, making everything a choppy, lumpy mess. On the 23rd and 24th, strong winds hit 28 mph, which is just raw. There are a few brief windows of clean, cross-off wind on the 15th, 16th, and 26th, but the swell is either way too small or the period is all wrong. Honestly, a setup like this on a reef is more interesting for kite surfing than trying to scratch for a 1 ft crumbler.
There is simply no stand-out surf on offer here, and no bright spot to look forward to. For a reef like Portwrinkle that's inconsistent at the best of times, a blank run this long is just how it goes sometimes. Keep the board in the car, but don't get your hopes up.
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.
