The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s shaping up for State Line over the next couple of weeks.

Right off the bat, I gotta be straight with you – the first week and a half is a bit of a tough one. There’s surf on offer, but it’s mostly marginal, with a lot of cross-shore wind and bumpy conditions. The water temp is sitting at 57°F, which is about average for this time of year, so nothing wild there.

The earliest recommendation we get is for Sunday afternoon, the 6th of September. We’ve got a 3ft SSW swell with a long 15-second period, which means it’s a proper groundswell – good energy, but it’s coming in with a 12 mph cross-shore wind. The combined energy is 669 (moderate), so there’s some push, but the wind is gonna make it choppy. Not the best start.

Monday morning, the 7th, is a little smaller at 3ft from the same direction, but that cross-shore wind is still there. The afternoon, however, is interesting. We get a 7ft NW swell, but the period drops to a short 6 seconds. That’s a windswell, and it’s gonna be a bit messy. The wind shifts to a cross-offshore from the NNW at 16 mph, which cleans it up, but the short period means it’ll be a bit lumpy. Combined energy is 651 (moderate). This one’s more for the experienced crew – 7ft is getting into the “too big for beginners” territory.

The real standout, if you can wait, is the very end of the run. We’ve got a few days of total junk in the middle – lots of cross-shore winds, some poor surf conditions, and some very small swells. But hold on to your board.

Saturday the 19th of September shows some promise. The swell is small, 2ft from the SW, but the period is 18 seconds – that’s a long-period groundswell. The big news is the wind. On Saturday afternoon, we get glassy conditions. That’s flat calm, no wind. Combined energy is 379 (moderate). For a small wave, it’s going to be silky smooth. This is a great option for a longboard or a funboard.

But the true best on offer, the one I’m getting excited about, is Sunday the 20th of September. The afternoon session is looking magic. A 3ft SW swell with a 19-second period, and the wind is flat calm, glassy. The combined energy is 548 (moderate). The file says “expect very good surf conditions,” and I’m buying it. It’s small, but it’ll be absolutely perfect. The long period makes it a bit straight for a beach break, but State Line can handle it. This is the one to circle on the calendar.

Monday the 21st also looks good in the afternoon – 3ft, 18-second period, not a breath of wind, glassy. Another beauty.

So, to sum it up: the first week is a grind. Mostly cross-shore winds and average quality. The second week, from the 19th onward, is where the magic happens. The absolute standout is Sunday the 20th of September afternoon. Get on it.

Rusty, signing off.

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.
