The Lowdown
G’day, Rusty here with a look at the next couple of weeks around Windang Island. This reef and point loves a south-east to south swell, and we’ve got a slow start before the real juice shows up.
The first few days, swell hangs around 6 ft to 6 ft from the ENE with a solid 11-second period and clean conditions each morning thanks to a light cross-off breeze. Water temp’s 65°, a touch warmer than usual for this time of year. Sunday and Monday mornings are the pick—clean, solid waves with moderate energy around 866 on Sunday morning. But the real standout is a week away.
Tuesday drops off, and by Wednesday we’re into smaller 3 ft swell with a classic W offshore—clean but nothing exciting. Thursday brings a shift to shorter-period S swell, and Friday sees a 5 ft S swell with 8-9 seconds and offshore wind in the afternoon. Surfable, but not special.
Now, Sunday, 26 July, is the one. Swell cranks to a solid 8 ft from the south with a very long 12-second period. Combined energy is a massive 2785—that’s serious power. Light cross-off wind in the morning means clean, heavy waves. This is expert-only territory, especially on reef and point. Expect long, hollow lines with big gaps between sets. If you’re skilled, this is your window. The afternoon gets a bit dicey with light cross-on wind, so paddle early.
After that, the swell fades fast through the end of July and into early August. Monday 27th is messy with cross-shore wind, then tiny surf for the rest of the week. There’s a glimmer on Sunday morning, 2 August, when it goes dead glassy with 4 ft SSE swell and zero wind—clean as a mirror, but energy is moderate (366). More of a longboard session. Crowds are possible at Windang Island, but that big 26 July swell will keep most people honest.
Bottom line: the first few mornings are worth it, but the absolute standout is the morning of 26 July—big south swell, clean offshore, and a reef that knows what to do with it. If you’re not confident at 8 ft, watch from the cliffs.
Rusty.

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.

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.
