The Lowdown
Alright, Rusty here. Let’s talk about Windansea.
Truth is, the next two weeks are a tough watch. The water’s sitting at nearly 72°F, which is a solid 4°F warmer than it should be for this time of year – feels like summer has overstayed its welcome.
We start off on Friday the 11th with a tiny 3ft swell from the southwest, but the wind is cross-shore and it’s choppy. That sets the tone for the next week and a half. Most days the swell is just 2 to 3ft, wind is cross-on or onshore, and the energy is weak. The whole stretch from the 11th through the 21st is mostly a write-off – there’s a solid 10-day gap where you won’t find anything clean.
The one moment that stands out is the Sunday morning of the 20th. The swell picks up to a clean 3ft of groundswell from the southwest, with a long period of 18 seconds, and the combined energy hits 626 (moderate energy). The wind is light cross-on, which is the best we’ll see. It’s still a marginal call, but that dawn session is the only time the reef has a chance to show its face. For the rest, you’re better off staying home or waiting for a better pattern.
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.
