The Lowdown

Alright, Rusty here. Let’s talk State Line over the next 16 days. It’s a pretty rough start, and the water’s a touch warmer than usual for August, which is the one bit of comfort early on.

Monday the 10th gets going with small, weak swell and a fresh cross-offshore breeze – looks clean but barely a ripple. Tuesday the 11th morning is even smaller, and by the afternoon you get a big, sloppy 10-foot swell (976 combined energy) with short period and strong wind. That’s a mess for a surfboard, but might be a kite session if you’re into that.

Wednesday the 12th afternoon brings a massive 10-foot swell (1207 combined energy) with clean conditions – but it’s way too big for State Line, experts only. Thursday the 13th and Friday the 14th slide back into marginal, lumpy conditions with cross-shore winds and mediocre swell.

From Saturday the 15th through Wednesday the 19th, it’s a long, flat run of tiny SSW swell (mostly 2 to 3 feet) with onshore or light cross-onshore wind. The period is long (14–18 seconds), so there’s some groundswell feel, but you’ll be waiting forever for a knee-high wave. Not worth the paddle.

Thursday the 20th afternoon shows a pulse: 6- to 7-foot NW swell with a short 6-second period and light cross-shore wind – marginal but surfable if you don’t mind some chop. Then we hit the real standout: Friday the 21st afternoon. That’s 8-foot NW swell (947 combined energy) with clean cross-offshore wind from the NNW. That’s the session – solid, clean waves. Big for beginners, but for everyone else, it’s the call.

Saturday the 22nd afternoon tops out at 10-foot NW swell again (959 combined energy), but once more it’s too big for this break – expert territory only. After that, it fades back to small, weak swell through the end of the outlook, with nothing else jumping out.

Best day: Friday the 21st afternoon. The rest is mostly small, messy, or oversized.

Rusty, out.

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.
