The Lowdown
Hey crew, Rusty here. Let’s break down what’s on the table for Windansea over the next couple weeks.
Right off the bat, there’s a few days with nothin’ worth talkin’ about. The first chance to get wet that’s even close to decent hits on Thursday the 10th of September. Water’s around 72°F, a touch warmer than usual for this time—not a big deal, but you’ll feel it.
Thursday the 10th afternoon is the pick of the bunch. Clear skies, a light cross-shore breeze, and a 0.9m swell from the SW with a 16-second period—proper groundswell, the kind Windansea loves. That reef break fires on SW swell, and the combined energy is moderate (485), with those long gaps between sets makin’ paddlin’ easier. It’s not big surf, but it’s the cleanest window in this whole forecast. Just a heads-up: crowds are a regular thing here, so be ready for company.
From Friday the 11th all the way through to late September, it’s pretty rough. Winds switch to cross or onshore, wave heights bounce between 0.6m and 1.1m, and periods drop to 7–9 seconds—too short for a reef to hold shape. There’s a few days around the 19th and 20th where the energy climbs into the 500s and 700s, and periods get back to 18–19 seconds, but the wind stays onshore or cross-onshore. That’s gonna leave it chopped up and sloppy. For a reef, that’s a no-go.
For the kite surfers, those onshore, choppy days might be more fun than paddling. For the rest of us, it’s a long wait. Your best bet is Thursday the 10th afternoon. After that, there’s a whole lotta nothin’ until maybe the very end of the run, and even then the wind’s still not playin’ nice. Keep the board waxed, but don’t get your hopes up.
This is Rusty, out.

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