The Lowdown
Alright, this is Rusty. Let’s have a look at what’s coming down the pipe for State Line over the next couple of weeks.
Right off the bat, the first few days are pretty grim. We’ve got a weak, short-period NW swell on Wednesday the 16th, but with a cross-on breeze chopping it up, it’s just not worth paddling out for. Thursday looks like a write-off with onshore wind and poor quality, so you can leave the boards in the car. Friday and Saturday the 18th and 19th see a drop in height but a spike in period from the SW, which could look tidy in theory, but the wave energy is weak (around 400-700) and the wind is either cross or cross-on, so you’re looking at small, bumpy lines. There’s nothing worth chasing here.
Now, the first real flash of something juicy shows up on Sunday the 20th afternoon. That NW swell jumps to 10ft, but the period is a short 7 seconds, so it’s going to be a bit of a close-out mess. More importantly, the combined energy rockets up to 1505, which is strong stuff, and the cross-shore wind won't help. However, that size makes it strictly a big-wave session for experienced surfers only, and even then, the quality isn't there. Monday the 21st has another 10ft pulse with a clean cross-off breeze, but again, too much juice and period is still short – this is getting into real dangerous territory for a beach break.
The standout window looks to be the morning of Wednesday the 23rd of September. We’ve got a NW swell of 6ft with a solid 10-second period, producing moderate wave energy (941). The key is the NNE offshore wind at just 5 km/h – that’s clean, lined-up surf. This is a legit option for an intermediate surfer, and it will hold some shape. The water temp anomaly is about average for this time of the year, so nothing out of the ordinary there.
Thursday the 24th afternoon offers another chance with a slightly smaller 4ft WNW swell and glassy conditions. That’s a good all-rounder for a fun, uncrowded session. The energy is moderate at 522, so longer period groundswell is on the cards, meaning better shape but longer waits.
After that, things get gnarly again. The weekend of the 26th and 27th sees another big pulse – 12ft on Friday the 25th afternoon and 7ft Saturday morning – both with clean winds on the 26th, but the size is a major caveat. Friday afternoon’s 12ft is way too big for anyone but experts, and Saturday’s 7ft with glassy conditions will be a serious, powerful wave. It’s worth looking at, but don't take a beginner crew.
The second week drifts back into smaller, marginal NW swell mixed with some long-period SW leftovers. There’s a hint of something on the 1st of October with a NW swell at 6ft and a longer 11-second period, which could provide some nice rides if the light cross-on wind isn't too messy. Overall, for the dedicated crew, the 23rd morning is the one to pencil in. The rest of the fortnight is either too small with bad wind or dangerously large.
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.
