The Lowdown
Alright folks, Rusty here. Let's have a look at what's coming down the pipe for Windansea. It's a reef break, fairly consistent, and exposed to the south-west.
Right off the bat, I gotta be straight with you: the next few weeks look pretty grim. We're looking at a long stretch of nothing special. The water is sitting at 73°, which is much warmer than we'd normally see this time of year – a full 5° above average.
The first glimmer of something even remotely rideable doesn't show up until Thursday, the 20th of August. Even then, it's a real struggle. We're talking about a small, weak south-west swell of just 2ft with a moderate combined energy (283). The wind is a light cross-onshore, so it's not going to be totally clean. Conditions are marginal at best, with questionable tide. This is a spot for the dedicated local who just needs to get wet, not for a good session.
We get a tiny window again on Friday the 21st, with the same sort of marginal 2ft swell (combined energy 201), but it's still scratched up by a light cross-onshore breeze. Honestly, it's not worth getting excited about.
There's a brief pause in the marginal calls, but things don't really improve. The pattern continues with small, onshore wind swells and even the "good" days are marked as "marginal surf forecast." A few days around the 24th and 26th of August show a similar story: 2ft to 2ft of swell, light winds, but still only a "1" out of 10. The swell direction is coming from the south-west, which is the optimum direction for this spot, but the size and energy just aren't there.
The best we can hope for in this whole 16-day window is a couple of days late in the month. The 29th of August shows a 3ft south-west swell (combined energy 477), but the wind is a light cross-onshore, which will keep it a bit bumpy. The 30th of August has a similar 3ft swell (combined energy 383 and 394), but with a light onshore or cross-onshore breeze. Even then, the forecast scores are bottom of the barrel.
Honestly, for the next two and a half weeks, Windansea is a no-go for a proper surf. The combined energy stays in the low to moderate hundreds, and the wave comments are all "poor surf conditions" or "marginal." There's no standout session here. If you're desperate, keep an eye on that last weekend of August for a bumpy, knee-high wave, but don't hold your breath. The forecast is a bit more reliable for the near term, and the long-range stuff is just as bad.
There's nothing here for beginners or experts. The swell is tiny, and the quality is poor. It's a tough stretch.
Rusty.

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.
