The Lowdown
Alright, let's talk about Windang Island. This is a reef and point setup, and it's pretty consistent, but the next couple of weeks are a mixed bag.
The water's a bit warmer than usual for July, sitting at about 65°F, which is a nice touch.
Honestly, the first few days are a write-off. Tuesday and Wednesday morning are flat, but then Wednesday morning (July 15th) kicks in with a solid 8ft S swell and a clean cross-offshore breeze. The energy is immense at 2174, but that's expert-only territory. The swell's got a 10-second period, so it's got some push.
After that, it drops off. Thursday morning has 7ft S swell, but the period is down to 8 seconds, so it loses some grunt. Then we hit a real lull from Friday the 17th through the middle of the next week. Lots of small, crummy surf with cross-shore winds. A few days are barely rideable.
Now, here's the good news. We've got a run of quality coming from July 23rd. The swell switches to the E, and it's a solid 6ft to 6ft, with a long 12-second period – that's proper groundswell. The energy is strong (851 to 999). The morning of the 23rd has clean cross-offshore winds, and the 24th and 25th are looking glassy or with light offshore breezes. That's a killer stretch. The best of the bunch? I'm picking the morning of the 23rd – that first pulse of long-period, solid E swell with the cleanest conditions. It's a bit of a wait, but it's got the goods.
The 27th and 28th keep the E swell coming, smaller but still with clean conditions. It's all about that 23rd to 25th window for the standout sessions.

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.
