The Lowdown
Alright, let's talk about Windansea. This is a classic reef setup, and it's a spot that needs a decent SW groundswell and clean conditions to really shine. Over the next 16 days, it's a bit of a waiting game.
Right now, the water is sitting at about 72°, which is a touch warmer than normal for this time of year. The early part of the outlook is a bit of a struggle. There's some swell, but it's just not lining up. The most promising window is actually the first morning, Saturday, September 5th. We've got a 3ft SW groundswell rolling in with a long 16-second period, and the wind is a light westerly. That's a decent combo for a reef break, and the combined energy is moderate. It's not going to be a world-beater, but with that light breeze, it could be the cleanest option we see for a while.
After that, it gets messy. The wind turns onshore for the rest of the weekend and into the next week, and while the swell sticks around 4ft to 6ft, the chop makes it a real chore. The combined energy climbs into the 900s and 1000s, but with cross-onshore winds, it's just not worth paddling out for a proper session. The setup is more interesting for a kite surfer than a traditional surfer through that period.
There's a real gap from Sunday, September 6th, all the way through until the middle of the next week. The swell drops right off, bottoming out on Tuesday, September 15th, with a tiny 2ft to 2ft swell and almost no energy in the water. It's a flat spell.
The light at the end of the tunnel is the following weekend. It's a long way off, so keep that in mind, but by Friday, September 18th, we see a new long-period groundswell from the SW, with a period of 19 seconds. The size is small, only 2ft, but the period is very long. That means the energy is there, and with a light offshore WSW wind, Windansea could actually have some clean, long-lining lines. It's a promising but less certain call for the long-term.
So, the standout is that Saturday morning, September 5th, for the cleanest conditions. The rest of the 16-day window is a lot of waiting for that potential pulse in the second week.

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.

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.
