The Lowdown
G'day, it’s Rusty. The week ahead has a slow start, but there's a couple of proper sessions on the menu.
Monday, July 27 starts off with a knee-high, 3 ft south swell at Windang Island, but the onshore breeze will ruin it by the afternoon. Water temp is 66°, just a touch above normal for the season. Tuesday and Wednesday are flat with clean conditions, but you're looking at a three-day stretch with no rideable waves.
Then Thursday the 30th fires up. A solid 7 ft south swell, combined with a clean cross-offshore breeze, will have the reef and point cranking. Combined wave energy is 1135, and it's pumping. Not for beginners – over 5 ft, so it's advanced territory. Friday isn't far behind: a 7 ft south swell at 10 seconds, with glassy conditions and a light southwesterly wind. Energy is 884, and it's a cracker. Saturday and Sunday have dropping swell, with 5 ft to 3 ft, but the wind gets messy.
Looking into the first week of August, Tuesday the 4th is a good call: a 5 ft south swell with a clean 12 mph westerly offshore. Combined energy is 429, and the morning will be clean. Later in the week, around the 9th, there's a whisper of a longer-period east swell, but it's a long way off. The 6 ft east swell with a cross-offshore breeze and 425 energy sounds good, but it's a week away, so hold your horses.
The top picks for the period are Thursday the 30th and Friday the 31st. That Thursday session with the 7 ft south swell is as good as it gets, and Friday is a close second. Tuesday the 4th with the offshore breeze is also a winner.
Stay stoked. 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. 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.
