The Lowdown
Hey folks, Rusty here. Let’s be straight: the next couple of weeks at Portwrinkle are a real snoozefest. This exposed reef needs a decent SW groundswell and light winds to turn on, but we’re looking at tiny, weak windswell for days. The water’s way warmer than normal right now, sitting at 66°, but that’s about the only bright spot.
The first real tease doesn’t show up until Sunday, August 16th. The early morning goes glassy with a bit of 3ft WSW swell and the combined energy is a meager 124 (moderate), but the period is a short 6 seconds – that’s just windswell junk. It’s surfable, but very ordinary. Don’t expect much shape.
The only other window that might get your attention is Thursday, August 20th, in the morning. A weak 4ft WSW swell rolls in with a 5-second period and combined energy of 83 (weak). Winds are light offshore from the WNW, cleaning it up, but that period is way too short to wrap in properly. Again, you’ll be scratching for anything rideable.
Other than those two mornings, every other slot is either flat, blown out by onshores (lots of moderate to fresh SSW, WSW, and W winds), or just too small. The swell height barely cracks 2ft all week, and when it does, the period is pathetic. You’d be doing more paddling than surfing.
Honestly, if you’re a beginner, stay out of the water on the days it’s over 2ft – the cross-onshore chop will be a frustrating mess. For the rest of us, keep the board in the car and wait for the next real groundswell. There’s nothing here worth chasing in the next 16 days.

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.

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.
