The Lowdown

G'day, Rusty here. Let's break down what's cooking at State Line for the next couple of weeks. I'll be honest – it's a slow burner. The opening days are pretty weak, with small, junky waves and a light cross-onshore breeze messing with the surface. The water's sitting at about 59°F, which is just a touch warmer than normal for this time of year – nothing special.

Things finally wake up on Saturday, August 29th. The morning still feels average with 2ft SSW groundswell and a long 18-second period, but the 15 km/h cross-shore wind leaves a bit of texture. The afternoon is where you see the pulse – swell picks up to 4ft from the SSW, period still at 18 seconds, and the combined energy hits a solid moderate 1138. The wind is cross-shore at 20 km/h, so not glassy, but it's the first real push of energy. The SSW direction lines up well with the exposed SW-facing break, so there's some proper grunt.

Sunday the 30th is similar – morning has 4ft SSW swell with 812 energy, but a cross-onshore wind. Afternoon drops to 3ft. Then Monday, August 31st, gives you a little window of perfection. The morning is dead calm – glassy conditions with a light 5 km/h wind from the SSW, and a clean 3ft SSW swell. It's small, but glassy is glassy, and the 14-second period gives it a nice shape. That's the best bet for a fun, clean session without too many people – just 'sometimes' crowded at State Line.

After that, it dries up. The first week of September is mostly small and messy, with cross-shore winds and swell barely reaching 3ft. Not worth your time. There's a spike on Thursday, September 3rd – the afternoon shows 8ft of short-period NW windswell (7 seconds) with 966 energy, but a strong 40 km/h NNW wind. It's cross-offshore so the surface is clean, but 8ft is expert-only territory, and the short period makes it nasty. Not a fun paddle.

Another one to watch is Thursday, September 10th, in the afternoon. That's a 8ft NW swell with a 10-second period and a huge 1464 combined energy – that's strong. The wind is light and cross-on at 5 km/h, so the surface is clean. The NW direction isn't the break's perfect SW angle, but with that much energy, it'll bend in. Still, 8ft is big for most, and it's over a week away, so keep it on the radar but don't bet the farm.

If you want a solid wave, hit that Monday the 31st glassy morning. After that, there's a long dry spell until that mid-September pulse, and even that's a gamble.

Rusty.

Information about the State Line Surf forecast

The above surf forecast table for State Line provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at State Line can be found by selecting the local surf guide option on the grey menu. Our State Line 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 (State Line) 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 State Line 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.
