The Lowdown
Alright, Rusty here. Let's break down the next couple of weeks at Windansea.
Honestly, it’s looking pretty bleak for the reef. We’ve got a long stretch of tiny, wind-chopped junk on the horizon. The water is hanging at 72°F, which is about 4°F warmer than normal – you’ll be sweating in a spring suit.
The first week is a total bust. There's a pulse of energy Monday afternoon the 25th with a 3ft SSW swell at 13 seconds, and a combined energy of 505 (moderate), but the wind is onshore, making it a messy crumble. That just keeps happening. Wednesday the 27th morning shows a 4ft SSW swell (period 12 sec, energy 604), but it’s cross-onshore. Looks promising from the beach, but it’s chopped up. Thursday the 28th and Friday the 29th have bigger, longer-period SW swells (16 sec, energy up to 769), but again, cross-onshore wind ruins it. Nothing here is worth paddling out for.
Then we hit a dead zone. From Saturday the 30th of August all the way to Monday the 8th of September, the surf is tiny – mostly 2-3ft – and the wind stays either onshore or cross-onshore. The energy is weak to moderate (235–827), but the wind kills any chance of a clean face. There is a brief moment on the morning of Tuesday the 1st of September with a 4ft SSW swell and a light cross-onshore breeze (3 mph), but it’s not enough to get excited about.
There is no standout window here. The best might be the afternoon of the 25th, or maybe the morning of the 27th, but both are blown out. The long-period (16-18 sec) swells are pure groundswell, which would be perfect for the reef if we had offshore wind, but we don't. The break is exposed to the SW, and the wind keeps coming from that direction. Save your energy.
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.
