The Lowdown

G’day, Rusty here, checkin’ in from the local stretch. We’ve got a mixed bag over the next couple of weeks, with a few windows that’ll get the heart pumping, but plenty of flat or messy days in between. Let’s break it down.

The first real action kicks off Thursday morning, 10th September, at Windang Island (reef and point). We’re lookin’ at a solid 8ft swell from the S, with a period of 10 seconds, and the wind’s blowin’ SSW at 12 mph, which is cross-offshore. This setup is pumpin’ some serious energy – the combined swell energy is 2160, which is strong. The water temp’s about average for this time of year, so no surprises there. This is a standout for the whole outlook: advanced surfers only, because 8ft is big, and the reef and point setup will handle that long-period groundswell beautifully. The cross-off wind will keep it clean, so expect some proper barrels. Crowds are possible, as it’s a known spot.

Thursday afternoon fades, with the swell droppin’ to 7ft and the wind swingin’ cross-shore, makin’ things choppy. Friday morning, 11th September, drops further to 5ft with a light cross-on wind, which is a bit frustrating – the swell’s there but the wind’s not helpin’. The rest of the first week into the weekend is a write-off: tiny swells, onshore winds, and poor conditions. From Saturday, 12th September, through Monday, 14th September, we’ve got waves under 3ft, with wind from the NE and ENE, all cross-on or cross-shore, producin’ choppy, messy surf. The combined energy drops to as low as 156, so it’s weak.

Tuesday, 15th September, shows a bit of a pulse: morning’s a mess with 3ft and a short 5-second period, but the afternoon brings a 7ft swell from the SSE with 9 seconds, and though the wind is cross-shore, the energy jumps to 670. Still, it’s marginal, and the tide might be an issue. Wednesday, 16th September, is similar with 5ft, but the wind stays cross-shore, killin’ the quality.

Then we hit a big gap. From Thursday, 17th September, through to the morning of Saturday, 19th September, it’s pretty bleak: tiny waves, onshore winds, and low energy. Friday, 18th September, is a highlight in a bad way – only 2ft, but the wind is cross-offshore from the SSW at 3 mph, so it’s clean but tiny. That’s more for a longboard if you’re desperate.

Now, the second standout comes on Saturday, 19th September morning. The swell jumps to 10ft from the S with a 10-second period, and the combined energy hits 2591. That’s very strong. The wind is cross-on from the NNE at 9 mph, so it’ll be a bit bumpy, but that’s a lot of water movin’. This is for experts only – 10ft is serious. The crowd profile says “sometimes,” so you might have a few others out there, but it’s worth it for the power.

The rest of the 19th and into Sunday, 20th September, has some promise: Sunday afternoon sees a 3ft swell from the S with an 11-second period, and the wind goes offshore from the WSW at 12 mph. The combined energy is 387, and the conditions are clean. That’s a good session for a smaller board, but not a standout.

The tail end of the outlook, from Monday, 21st September, onward, is mostly poor. Winds are onshore or cross-shore, and swells are either too small or too choppy. Thursday, 24th September afternoon, though, is a real gem: 5ft from the S with an 11-second period, and the wind goes glassy – literally “glass” from the S at 3 mph. The combined energy is 588, and the forecast says “expect very good surf conditions.” That’s a long-range standout, but it’s a week and a half away, so keep an eye on it. Friday, 25th September morning, also looks clean with 4ft and offshore wind from the WNW at 6 mph, with 332 energy.

So, if you’re an advanced surfer, circle Thursday 10th September morning and Saturday 19th September morning for the biggest, most powerful waves. For the cleaner, smaller days, Thursday 24th September afternoon is your best bet for a glassy session. The rest of the time, it’s either flat or messy, but that’s the game.

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.
