The Lowdown
G’day, Rusty here. Look, I’ve been staring at the charts for Windang Island, and honestly, the next 16 days are a bit of a mixed bag. We’ve got a real slow start – nothing worth paddling out for until Thursday the 30th of July. After that, there are a few windows of clean, fun-sized waves, but you’ve gotta pick your moments. The long-range stuff into the second week looks pretty average, with a lot of onshore wind and chop.
The first real chance to get wet comes on Thursday morning, the 30th of July. Windang Island wakes up with a clean 4ft S swell, period around 9 seconds, and glassy conditions with a light SSW breeze. The water’s sitting at 66°F, which is a touch warmer than normal for this time of year, so that’s a nice bonus. The combined energy is moderate (252), and it’s got that exposed SE reef and point setup working. It’s not huge, but it’ll be clean and fun for the advanced crew. Thursday afternoon turns a bit ugly with cross-onshore wind, so make the most of the morning.
Friday the 31st of July has a bit more size – 6ft S swell in the morning, but the wind is straight cross-shore, and the conditions are marginal. The combined energy is strong (722), but you’ll be battling chop. The period is only 10 seconds, so it’s a bit junky. Saturday morning, the 1st of August, is a standout. The swell drops to 5ft from the SSE, but it’s glassy with a light SW breeze, and the combined energy is still solid (480). This is your best bet for the first week – clean, punchy waves on the reef. Saturday afternoon goes to shit with a NE sea breeze, so get it early.
Sunday the 2nd of August is another good one. The swell is 4ft from the SSE, but the wind is light cross-offshore from the N, keeping it clean. The energy is moderate (291) and the period is 10 seconds. It’s not a monster, but it’ll be fun. After that, the surf starts to fade through Monday and Tuesday, dropping to knee-high mush with very little energy.
Now, into the second week, things get messy. Thursday the 6th of August sees a bump in swell – 6ft from the SSE, with a strong combined energy (663). The morning looks clean with a cross-offshore SW wind at 16 mph, but it’s a moderate breeze. This could be a decent session for the experienced, but the wind is gusty. Friday the 7th of August has a bigger 8ft SSE swell, but it’s cross-onshore from the ENE and choppy – that’s expert-only territory, and honestly, it looks more like a day for the kite surfers. The rest of the second week is a write-off: small, choppy, and onshore. The last few days from the 10th of August onwards are tiny, with weak energy and poor conditions.
Overall, the standout is Saturday morning, the 1st of August: glassy, clean, and a solid 5ft SSE swell. Sunday the 2nd is a close second. The rest is either marginal or just plain ugly. It’s not a total blank, but you’ve gotta be sharp.
Rusty.
