The Lowdown
Alright folks, Rusty here. Let’s get into it for Windang Island. This is a reef and point set-up that needs a solid SE swell to really fire, and the next couple of weeks have a bit of a slow start before some serious juice shows up.
The week kicks off with a bit of a limp start. The first swell we see is on Monday the 20th, but it’s a messy 5 ft from the ENE with a cross-onshore wind – that’s a skip. The water is sitting at 66°, which is a touch warmer than normal for this time of year, so that’s a nice surprise if you’re in a spring suit. Tuesday and Wednesday are mostly small and marginal, but Wednesday morning the 22nd is the first real glimmer of hope. Offshore west wind, clean conditions, and a clean 3 ft from the ENE. It’s small, but it’s workable. The energy is weak at 204 (combined energy of all swells directed here). Thursday the 23rd drops right off with 2 ft and a strong offshore wind, making it too clean for the size.
Friday the 24th is where things start to get interesting. A new S swell rolls in at 5 ft early with a clean cross-offshore wind from the WSW. The energy is moderate at 381. That morning session looks like the pick of the first week – clean, punchy, and the wind is in your favour. Saturday the 25th and Sunday the 26th keep the S swell going at 3-4 ft with glassy offshore mornings. The period is hitting 11 seconds, which is proper groundswell, and that’s going to groom the point nicely. The energy is moderate (339-380). These are your best bets for the first week – clean, consistent, and not too crowded.
Then there’s a quiet patch from Monday the 27th through Wednesday the 29th. The swell drops to knee-high, and the energy falls right off – 35 on the 28th. You’re better off doing something else.
Now, here’s the big one. Thursday the 30th of July. The guidance is showing a real pulse of S groundswell: 6 ft morning, 6 ft afternoon, with a period of 12-13 seconds – that’s a very long period groundswell. The energy is through the roof at 1192 and 817. The wind is offshore or light cross-offshore, keeping it clean. This is a standout. The point will be handling this beautifully, with long, lined-up walls. It’s a touch over 5 ft, so it’s getting into advanced territory, and the long period might make it a bit straight at the beach, but on the reef and point it’s going to be magic. That afternoon session is the pick.
Friday the 31st and Saturday the 1st of August ease off but stay clean with offshore winds. The morning of the 1st is glassy – flat calm, 4 ft from the S, and perfect conditions. That’s a lot of fun for the weekend warrior.
The following week has another pulse. Monday the 3rd of August brings a 6 ft S swell with a short 8-second period, but strong offshore wind keeps it clean. The energy is 631. Tuesday the 4th of August is the highlight of the whole forecast. An absolute bomb: 10 ft from the S, 11-second period, glassy conditions, and the energy is a monstrous 3755. That is for experienced surfers only – that’s big, powerful, and will be heaving. The wind is dead calm in the morning. If you’re an expert, that’s your day. The afternoon shifts to an onshore wind, so it’s morning or bust.
Overall, the standout window is the morning of Thursday the 30th of July, with the afternoon even cleaner, and then the expert-level session on the morning of Tuesday the 4th of August. The first week has small but clean windows on the 22nd, 24th, and 25th. Don’t bother with the 27th-29th. It’s a reef and point, so it handles the long period groundswell well, and with the offshore winds, it’s going to be a proper session.
Rusty out.

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.
