The Lowdown
Alright, Rusty here again. Let's talk about Windang Island in feet and knots.
The water's about 66°F, running a touch warmer than average for this time of year – nice for a winter dip.
This reef and point needs a solid SE swell to really light up. The week starts Monday the 20th with a morning pulse around 5 feet from the ENE, 11-second period, combined energy at 723. Light cross-off breeze from the NNW keeps it clean. That's a good start. Afternoon turns messy with a cross-on wind.
Tuesday the 21st morning is clean again but the swell drops to 4 feet, energy down to 392 – rideable but not special. Afternoon is another write-off. Wednesday the 22nd morning has a light offshore from the W, waves around 3 feet, energy 202. Small but clean. The afternoon holds a gentle offshore with 3 feet – still ordinary.
Thursday the 23rd is tiny – 2 feet, moderate offshore, energy only 83. Clean but weak. Friday the 24th morning brings a new S swell at 5 feet, short 8-second period, but the cross-off breeze keeps it clean, energy 312. Friday afternoon is odd: 1 feet but with an 18-second period from the SSE. That’s a very long period groundswell – it'll be slow and fat on the face, but this reef might give it some shape. Energy still moderate at 292.
Saturday the 25th builds: morning moderate offshore with 3 feet from the S, energy 241. Afternoon goes to 3 feet with a 12-second period and gentle offshore, energy 441. Clean and building.
Sunday the 26th morning is the first real standout. Glassy conditions, light SW wind, 5 feet from the S, 11-second period, combined energy of 452. That's clean, solid winter surf. Get it early – the afternoon turns cross-on and goes bad.
Monday the 27th is glassy again in the morning, flat calm, 4 feet from the SSE, energy 285. Clean but smaller. Tuesday the 28th has moderate offshore winds, waves around 3 and 2 feet. Clean but small. Wednesday the 29th gets hit by a fresh 30 km/h SSW wind – unpleasant.
Then the big one: Thursday the 30th. Morning has 5 feet from the SSE with a very long 15-second period and combined energy of 1973. That's strong. Cross-off wind keeps it clean, but the long period might make it a bit straight for this point. Afternoon jumps to 8 feet with energy at 2644 – that is powerful. Cross-shore wind adds chop. That size is for experts only.
Friday the 31st holds around 6 feet from the SSE, but winds are onshore and cross-shore – marginal. Saturday the 1st of August morning is the other standout: 6 feet from the SSE, 12-second period, energy 876, and glassy. A clean, solid winter swell with no wind – that's as good as it gets. The afternoon drops off.
Sunday the 2nd and beyond stay smaller, with inconsistent quality. There's a last bump on Tuesday the 4th of August with 5 feet from the S, but cross and cross-on winds hurt the surface.
Best bets: Sunday the 26th of July morning – glassy, 5 feet S swell. And Saturday the 1st of August morning – glassy, 6 feet SSE swell. Expect a few others out there on those clean days – Windang Island can get busy.
Rusty out.

Information about the Windang Island Surf forecast
The above surf forecast table for Windang Island provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Windang Island can be found by selecting the local surf guide option on the grey menu. Our Windang Island 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 (Windang Island) 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 Windang Island 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.
