The Lowdown

Alright folks, Rusty here. Let's have a look at what State Line has in store for us over the next couple of weeks. It’s a bit of a mixed bag, so we’ll need to pick our moments.

Right out of the gate, we’ve got some small, clean-ish surf but nothing worth paddling out for just yet. The real story starts to build towards the end of the month. The first standout window hits on Sunday, the 30th of August. That afternoon we’re seeing a 10ft swell from the NW with clean conditions and a cross-off breeze. Now, that’s a lot of water – definitely one for the experienced crew only, as it’s over 8ft. The period is a short 7 seconds, so it’ll be a bit of a bumpy, close-out affair at a beach break, but if you’ve got the skills and a big board, there’ll be some heavy moments.

The water at State Line is sitting at 60° right now, which is a touch warmer than usual for this time of year, so you won’t need the thickest wetsuit.

We then hit a long, slow patch. Through the first week of September, it’s pretty grim. Small, choppy, and onshore winds dominate. Tuesday the 1st and Wednesday the 2nd are write-offs with poor conditions. There’s a bigger pulse on Thursday the 3rd with 8ft swell from the WNW, but the wind is onshore again, making it a messy, lumpy affair. Not worth it.

The second week of September doesn’t bring much joy either. From the 4th through to the 11th, it's a series of small, cross-shore slop with weak energy – mostly in the 300 to 700 range. Nothing really stands out. Crowds are “sometimes” an issue here, but with this quality, I doubt many will be out.

There is one little bright spot right at the end of the outlook. On Saturday the 12th of September, the morning shows some promise. We’ve got a 3ft groundswell from the SW with a nice 15-second period and clean, cross-off winds. The combined energy is moderate (450). That’s a long-period swell, so it’ll have real shape and power, but at a beach break like State Line, it might break a bit straight. Still, with those clean conditions, it’s the only real session worth aiming for in that whole second week. It’s a long way out, so keep an eye on it.

So, to wrap it up: the standout is Sunday the 30th of August for the big stuff if you’re an expert, and the morning of Saturday the 12th of September is a promising but more uncertain option for a cleaner, smaller wave. The rest of the time, maybe take a break.

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.
