The Lowdown

Alright, let's get straight into it.

First up, the next week and a half is looking pretty quiet for State Line. The truth is, we’re going through a long, drawn-out flat spell. From now through the end of August and into the first days of September, the swell is small and the conditions are messy. There is no real clean, rideable surf to speak of during that stretch. It’s a big gap – over a week – with nothing that gets the heart pumping. The water temperature is sitting around 60°, which is a touch warmer than normal for this time of year, but you won’t be in a rush to paddle out anyway.

The first hint of something happening shows up on the afternoon of Wednesday, the 2nd of September. That's the standout. We get a solid pulse of swell from the NW pushing 10 ft out of the northwest with a short period of 8 seconds. The wind is light and cross-shore, which keeps things clean. But here’s the catch – this is way too much size for State Line. With heights like that and a short-period swell, it’s going to be a washing machine with a ton of energy, measuring 1312 on the combined energy scale. This is strictly for the experienced crew, if anyone even gets in. Beggars and beginners stay well away. For everyone else, this is a spectacle, not a session.

Before that, on the morning of the 2nd, there’s a smaller pulse of 6 ft from the NW, but the conditions are cross-onshore with ripples, so not really worth chasing.

The rest of the first week of September fades back into small, mediocre swell with cross-shore winds. The energy drops back into the hundreds, and the waves are just nothing special. A few days with 3 ft from the SSW and periods around 16-18 seconds might offer something, but the wind is never truly good, and the quality is lacking.

So, bottom line: it’s a long wait for a brief, oversized event. If you’re an expert and you want to see some power on the 2nd of September afternoon, it’s your only real window. Otherwise, it’s a blank run for this area.

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.
