The Lowdown
Alright, folks. Rusty here. Let’s get into the outlook for our local reef. We’ve got a bit of a mixed bag over the next two weeks, so let’s break it down.
For the first few days, what we’re seeing is a long-period groundswell from the southwest, which is a solid direction for the reef. The swell energy is pretty moderate early on, sitting around 629 (combined energy), with the swell coming in at 4 ft. The water is running about average for the time of year, so no wetsuit surprises. The biggest issue is that it’s going to be a bit of a slow start—Tuesday morning is looking marginal, with a light offshore breeze making it clean, but tide conditions are the only thing holding it back.
Into Wednesday and Thursday, the swell drops off a bit, but the wind stays tricky, shifting into a cross-onshore. The energy drops to around 455-560, and the conditions get choppy. Not our best days. We do see a bit of a pulse on Thursday morning with a 4 ft, 13-second swell, but it’s still marginal.
Now, here’s the real standout for the entire period. Friday, July 31st, that’s the one to circle. The swell jumps up to 7 ft in the afternoon, with a 15-second period, and the combined energy goes through the roof at 1979. That’s solid, powerful groundswell. The wind is offshore from the west-northwest, which is perfect for this reef. Make no mistake, this is a big swell—over 8 ft is only for experts. The reef is going to be thick and hollow, but it’s a tricky wave. If you’re not on your game, this one will sort you out. The crowds are often at Windansea, so expect a lineup.
The next week drops off a lot. Winds stay cross-onshore or onshore, and the swell loses its juice. By August 2nd, we’re down to 2 ft and 253 energy, which is weak. The period drops too, and the wind is messy. From August 3rd to the 5th, it’s real small with poor conditions. The energy is under 300, and it’s barely worth paddling out. There’s a four-day gap of pretty poor surf here.
So, the bottom line: if you’re an expert, the morning of July 31st and that afternoon session is the time to be out. It’s a big, long-period, offshore reef setup. The rest of the window is mostly marginal or poor. Stay patient.
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.
