The Lowdown
Alright, Rusty here, let’s run through the numbers for the next couple of weeks. We’ve got a big swell on the horizon, but only a few clean windows.
First up, Conto Springs. It’s a reef setup, exposed to the WSW swell. The water is sitting at 66°, which is a touch warmer than usual for this time of year.
The story starts with a bang, but not a good one. Monday the 17th, we’ve got a massive 18 foot swell with a very long 17-second period. The combined energy is a massive 16575, which is just insane. The wind is howling from the WSW at 28 mph, a strong cross-onshore that’s going to make a mess of it. This is way too big for anyone, and the conditions are going to be a blown-out nightmare. More of a kite-surfing situation than paddle surfing.
We’ve got a few days of oversized, choppy conditions. The swell stays over 13 feet through the 18th, 19th, and 20th, with moderate to fresh cross-onshore winds. The energy is still high, in the 6000 to 11000 range, but it’s all just a lumpy, messy ocean.
The first real glimmer of hope comes on Saturday the 22nd. The morning has glassy conditions with a light WNW wind, and we’re still looking at a solid 10 foot swell from the SW with a 16-second period. The energy is a moderate 4084. The wind is glassy, so the surface will be clean. The afternoon cleans up even more with a light SSW cross-off wind and the swell drops to 8 feet. This is a standout. It’s a big swell, so it’s for experienced surfers only, but the conditions will be excellent for those who are up for it.
Sunday the 23rd and Monday the 24th, the wind picks up again, and the quality drops. The swell holds around 10 feet, but the wind is the enemy.
We get another chance on the 25th and 26th. The swell stays around 11 to 13 feet, with gentle cross-shore winds. It’s surfable, but not the cleanest.
Then, on Thursday the 27th, we get another glassy morning. An 8 foot SW swell with a 14-second period, and glassy conditions. The energy is 2698, so it’s a bit smaller, but it’s clean. The afternoon also cleans up nicely with a light SSW cross-off wind. This is another solid window for experienced surfers.
The last week of the month and into September, the wind becomes a problem again. The 30th and 31st see a return of strong winds, including a near gale on the 31st, with an 11 to 13 foot swell. The first of September is no better, with strong onshore winds and a 15 foot swell.
So, the best windows are Saturday the 22nd and Thursday the 27th. Both have glassy or clean conditions and a solid, powerful swell from the SW. It’s not for the faint of heart, but if you’re an experienced surfer, those are the days.
Rusty.

A general guide to surfing at Conto Springs can be found by selecting the local surf guide option on the grey menu.

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 Conto Springs 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.
