The Lowdown
Alright folks, Rusty here, letting you know what's on the cards for Windang Island over the next couple of weeks.
We've got a mixed bag coming up, but there are some definite windows of opportunity if you're willing to pick your moments. The early part of the week is looking pretty tidy, with a solid pulse of south swell arriving. The standout is definitely going to be Sunday morning, the 26th of July. We're looking at a clean 6ft south swell with a 10-second period, and the wind is glassy out of the WSW. The energy is strong, coming in at (723), and it's shaping up to be a really good session. This is the pick of the bunch for the near term.
Saturday the 25th is also worth a paddle, with a clean 5ft south swell in the morning and a light offshore breeze from the west. The water temp is about average for this time of year, so nothing wild there. The afternoon on Saturday gets even better with glassy conditions and a 4ft swell, which is a real treat for a winter's afternoon.
Now, after that fine start, the surf really drops off. From Sunday afternoon onwards, we hit a flat spell. The wind goes onshore and the swell disappears, leaving us with tiny, poor-quality waves right through the end of July and into the first week of August. You're looking at at least a full week of nothing worth chasing, with tiny, choppy conditions.
Keep an eye on Thursday the 30th of July, though. The morning brings a clean 6ft south swell (388) with a cross-offshore breeze. It's a good option, but that Sunday morning is the real highlight.
Looking further out, the second week of August has a massive, long-period south swell forecast for around the 8th and 9th. We're talking 20ft and 18ft swells with a 12-second period. The energy readings are enormous (10348 and 8726). But here's the thing: that's way too big. This is a reef and point setup, and at that size, it's only for absolute experts. For most of us, it's a watch-and-wonder situation. The crowds are listed as "sometimes" here, but on a day like that, you'd expect a few brave souls having a look.
So, in a nutshell: hit it this Saturday and Sunday morning for some clean, fun glassy waves, then save your energy for the giant swell in the second week, but only if you've got the skill and the nerve.
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.

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.
