The Lowdown
Alright folks, Rusty here. Let's get real about what we’ve got on the cards for Windansea. This is a classic reef setup that needs everything to line up, and for the next sixteen days, it’s looking pretty flat and sad.
Right now, the water is reading at 73°, which is *much* warmer than normal for this time of year – definitely a spring suit kind of situation if you’re keen, but don’t expect much else to be on your side.
The first real chance of anything even remotely worth paddling out for shows up around Saturday the 19th, but even then, we're looking at a tiny 3ft SW groundswell. The period is a solid 18 seconds, which shows some deep-water energy, but it’s just not got any guts. The combined energy is moderate at best (519), and with the wind onshore and light, the surface won't be clean. It’s marginal at best.
Sunday the 20th and Monday the 21st roll in with the same story: 3ft to 3ft of SW swell, with periods bouncing between 17 and 18 seconds. The energy stays in the moderate range (504, then 603). The wind is cross-onshore or onshore, and the surf is still marginal. It’s just a blip of movement, not a proper session.
After that, from Tuesday the 22nd all the way through to the end of the period on Wednesday the 30th of September, it’s pretty much a dead zone. The swell drops or hangs around 2ft to 3ft, energy values fall, and the wind stays onshore or cross-onshore. The forecast flags everything as poor. There’s a long gap of about 9 days with no real hope.
Honestly, there’s nothing here that stands out. No standout swell, no clean glass-off windows. A few marginal slots around the 19th and 20th, but that’s the best it gets. If you’re a beginner, those tiny waves are safe enough, but for anyone with experience, it’s just not worth the effort.
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.
