The Lowdown

Alright folks, Rusty here. Let's have a look at what's cookin' for the next couple of weeks.

Well, it's a bit of a mixed bag, if I'm honest. The immediate outlook is pretty flat and the wind's been a pain, but there's a pulse of energy later on that's got my attention. The water temp is way down at 51°F and that's a massive 5°F colder than it should be for this time of year at State Line. That's a proper cold snap, so you'll want the thickest rubber you've got.

We kick off things on Friday the 17th of July, but honestly, it's a write-off. We've got a weak 3ft swell from the WNW with a long period of 17 seconds, but the wind is cross-on and the wave energy is in the moderate range (984). It's marginal at best. Saturday the 18th isn't much better in the morning, but the afternoon brings a bit of size up to 8ft. The problem is the period drops right off to a short 7 seconds and the wind is still cross. The swell energy is moderate (1295), but it's a messy, choppy mess. Sunday the 19th is more of the same with cross-shore winds and a short-period swell. It's not looking like a paddle session.

Now, Monday the 20th of July is where we get a glimmer of hope. We've got a drop in swell to 6ft from the NW, but the wind goes glassy. Both the morning and afternoon are completely glassed off. The swell period is still short at 8 seconds, but the combined energy is moderate (754 and 631). It'll be small, but if you're desperate for a cleanish wave, that's your window. After that, it drops right back to tiny 2ft stuff for the rest of the week.

The real standout, the one that's got me a little excited, is looking like Thursday the 30th of July. The afternoon session is showing a solid 12ft from the NW, but it's a short period at 8 seconds. The wind is a gentle cross-shore, and the wave energy is through the roof at a very strong 2052. But here's the catch – the file says it's predicted to be too big for this break. This is expert territory only. It's going to be a washing machine, and for a beach break, that short period is going to make it a bit of a wall. If you're a seasoned charger, you might get some bombs, but honestly, with that much power and short period, it might be more of a kite-surfing show than a paddle-out paradise. The 31st of July afternoon is showing the same issue with an 12ft swell and strong energy (1687), again too big for the spot.

So, to sum it up: the best bet for a clean, easy paddle is that glassy Monday the 20th. It's not big, but it's clean. The big pulse on the 30th and 31st is for the brave and the experienced only, and even then, it's a risky call this far out. The rest of the time? We're sitting on the sand.

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.
