The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming up for Windansea.
Alright, strap in, because it’s a bit of a rough stretch here. For the next sixteen days, we’re looking at a real flat spell. There’s nothing that’s really going to get the heart pumping. The water temperature is running much warmer than normal for this time of year, sitting at 76°, which is a good seven degrees above average. That’s very unusual.
The first few days are a write-off. Monday the 10th and Tuesday the 11th are all poor, with tiny 1ft to 2ft swell from the SW. The wind is onshore or cross-on, which is just going to mess up what little is there. The combined wave energy is weak at 293 and 290, respectively.
Wednesday the 12th and Thursday the 13th are no better. Still tiny, 2ft to 3ft, and the wind stays onshore. The energy picks up a bit through the week, hitting a moderate 440 on Thursday afternoon, but the wind is straight onshore, and the wave comment says it’s just poor. Friday the 14th is the same story.
The weekend – Saturday the 15th and Sunday the 16th – offers a little more size, with the swell bumping up to 3ft and 4ft, and the energy getting into the moderate range, hitting 565 and 596. But again, the wind is onshore or cross-on, and the conditions are labelled marginal at best. Not worth paddling out for.
The second week is just more of the same. From Monday the 17th through to Tuesday the 25th, the swell stays inconsiderate, from 1ft to 3ft, with persistent cross-on or onshore winds. The energy falls back below 400 most days. It’s a long, flat run.
There are no standout days here, no windows of clean swell with good wind. Honestly, Windansea is a classic reef, but this forecast looks more interesting for a swim than a surf.
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.
