G’day, I’m Rusty, and I’ve got my eye on Windang Island for the next couple of weeks. It’s a bit of a split forecast—some early fire, then a long, flat stretch that’ll give your board a rest.
Wednesday morning the 8th kicks off with an 8ft SE swell at 10 seconds. The combined energy is cooking at 1481, so there’s good power. Wind’s a cross-off from the SW at 12 mph, keeping things decently clean. This spot’s a reef and point, so that groundswell will wrap in well. Water temp is average for July. The size is a bit heavy for beginners—this is advanced territory.
Thursday morning the 9th drops to 5ft from the SE, still a 10-second period. Energy eases to 721, but the wind is a gentle cross-off from the SSW at 9 mph, so the face stays clean. That’s a really nice window—size is manageable, and the wind helps.
Friday morning the 10th is the one to circle. Swell is 5ft SE with a 9-second interval, energy at 325. Wind is glassy—dead calm from the WSW at 3 mph. That’s as good as it gets. Clean, lined-up waves with no wind bump. This is the standout of the whole outlook.
Saturday the 11th keeps it going—morning has a 4ft SE swell with clean cross-off NW wind at 6 mph. By the afternoon it’s smaller, 2ft from the ESE, but still clean. Sunday the 12th through Tuesday morning the 15th is a washout. Tiny swell, nothing over 2ft, and even though the wind is offshore and clean, there’s no energy. Readings are in the double digits—99, 48, 39, 24. Proper flat spell.
Wednesday afternoon the 15th shows a spike—4ft from the S, but it’s blowing 22 mph from the S with rain. Energy is back up to 310, but the wind is messy. Thursday the 16th jumps to 6ft from the S, 11-second period, energy at 815, but the southerly is screaming at 25 mph. That’s a huge cross-shore mess—looks better for kite gear than a paddle board.
From Friday the 17th onward, it’s all downhill. Tiny surf from 1ft to 3ft, weak energy under 140, and mostly variable light winds. Saturday the 18th morning has a clean 2ft SSE swell, but it’s barely surfable. That’s a week-long dry gap—no lie.
Best advice? Hit Windang Island on Friday morning the 10th for that glassy 5ft SE swell. Thursday morning the 9th is solid too. After that, the well’s dry. Keep the wax warm.

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.
