The Lowdown

Alright, let’s get into it. The next couple of weeks are a bit of a mess at State Line, honestly. There’s some serious size coming, but it’s gonna be a struggle to find the right window. We’re looking at a lot of days where the swell is just too big for this spot, which is a shame because the wind is often clean. It’s not going to be a total write-off, but you’re going to have to be picky.

The first real highlight is Saturday afternoon, August 8th. The swell is pushing 10ft from the NW with a 7-second period. The energy is moderate to strong at 1268, and the wind is a cross-offshore breeze that’s going to keep the face clean. This is the biggest, most powerful swell of the early period, and it’s going to be firing. This is a standout for sure.

Now, the middle of the week gets tricky. Sunday morning, August 9th, drops right off to 2ft and the wind is a cross-shore mess. That’s a no-go. Sunday afternoon is back up to 12ft from the NW, but that’s too big for State Line. It’s a similar story on Monday and Wednesday afternoons – all too big, even if the wind is off. The mornings are flat and junky. You’ll have a few days there where it’s either flat or closing out. It’s just pushing too much water for this break.

The standout of the second week is Sunday afternoon, August 16th. The swell has backed down to a much more manageable 3ft from the SSW with a 16-second period. That’s a proper groundswell, full of energy. The combined energy is moderate at 579, but the wind is completely glassy. That’s the cleanest the waves are going to be all week. The period is long, so it’ll have some push to it, but at this size, it’s going to be perfect for a log or a fun mid-length. It won’t be huge, but it will be clean and organized.

Wednesday morning, August 19th, and Thursday morning, August 20th, are also looking promising. Both mornings have that glassy, slight air wind, with swell around 5-5ft from the WNW. The period is a bit shorter, 9-10 seconds, but the energy is still solid. These are your days for a clean, fun, and rideable wave without the chaos of the big swells.

After that, the winds pick up again and the swell gets a bit inconsistent, so make the most of that Sunday-to-Thursday window in the second week. The big swells are for the experts, but the clean, smaller days are where the rest of us will have our fun.

Remember, State Line is fairly consistent, but it doesn’t handle the big stuff well. There’s a lot of chop and too much water moving around. The good news is, the forecast is always changing, so keep an eye on it.

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.
