Table - best surf conditions forecast for Windang Island over the next 16 days.
Righto, let's have a look at what's coming up for Windang Island over the next couple of weeks. This spot is a reef and point set-up, exposed to that south-east pulse we love. The water temp is sitting around 65°, which is pretty much average for this time of year, so nothing wild there.
The real action is a bit of a mixed bag to start. Saturday morning, the 11th of July, kicks off with a 4ft swell from the SE, clean and cross-off with light airs. Energy is moderate at 352, and it’s a decent little session to get the weekend started. But that afternoon the wind swings around, and things go flat and choppy, so make the most of the morning.
Sunday the 12th drops right off into tiny, weak 2ft surf with a long period ESE swell. The winds are offshore and clean, but there's no real power there (93 on the energy scale). It’s a skeg-dragging kind of day. Monday and Tuesday follow the same trend – tiny, weak, and not worth paddling out for.
Now, Wednesday the 15th of July is a different story. A solid 10ft south swell rolls in, with strong energy (1681). The morning looks clean with a cross-off wind, but that’s a lot of water. At over 8ft, it's firmly in the expert-only zone. If you’re a charger, you’ll love it, but beginners should stay well clear.
We then get a bit of a lull through to Saturday the 18th, with some ordinary conditions and tricky winds.
Hold onto your board, though, because Sunday the 19th of July is a serious standout. The morning brings a 6ft E swell with glassy conditions – wind is basically dead, so it'll be as clean as it gets. The energy is pumping at 770, and that combo of clean glass and a solid swell will have the lineup humming.
The next real highlight is Monday the 20th of July. The morning session is the pick of the forecast. We’re looking at a 8ft E groundswell, period of 12 seconds, with glassy conditions and energy at a whopping 1723. This is big, powerful, and perfect for experienced surfers on a point or reef. Winds are dead calm – you can almost hear the sets from here. Just be aware it's over 8ft, so only for the skilled crew.
Tuesday the 21st keeps the size but the wind picks up, making things a bit messier. Wednesday the 22nd is another big south swell day (8ft), but with a side-shore wind, it’ll be lumpy.
Looking into the second week, Thursday the 23rd of July cleans right up again. A 5ft E swell with a 12-second period and light cross-off winds brings very good conditions and energy at 898. That's a sweet, powerful wave for a solid session.
Friday the 24th offers a similar vibe in the morning with 4ft ESE groundswell and light wind, clean and punchy. The weekend of the 25th and 26th wraps things up nicely. Saturday has 6ft ESE swell with clean cross-off conditions all day – solid energy (792) and a great wave for the crowd. Sunday the 26th is a classic offshore day with 5ft E swell, moderate offshore wind, and clean lines. Energy is still decent at 588, so you’ll get some fun runners all session.
So the two true standouts are Sunday the 19th for that glassy, clean 6ft E swell and Monday the 20th for the big, powerful 8ft E groundswell in absolute glassy perfection. Get out there for those if you can.

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.
