The Lowdown

Alright, surfers, Rusty here. Let’s talk about what’s cookin’ at State Line. It’s gonna be a bit of a mixed bag, but we’ve got a couple of windows that are seriously worth a look.

The week kicks off with a solid little pulse. Monday morning, July 20th, we’ve got clean 5ft swell from the NW, and the wind is almost nothing out of the north. The water is sitting at 52°, which is a couple of degrees colder than you’d expect for this time of year, so you’ll want the thick rubber. That Monday afternoon is a standout – clean, head-high waves with no wind to mess ’em up.

After that, the surf drops off. Tuesday through Thursday is a bit of a snooze with small, wind-affected swell around 2ft to 4ft. The winds are light but mostly cross or cross-onshore, so it’s not going to be a priority.

Now, Friday, July 24th, things start to get interesting again. The main event is the afternoon. The swell drops to 3ft, but the period jumps to a very long 24 seconds. That’s a proper groundswell from the southwest. The wind is cross-shore but light, so it’ll be a bit choppy, but that long-period energy will wrap in nicely. This is a solid option for the intermediate crew.

The weekend of July 25th and 26th keeps the long-period SW swell coming, with heights around 3ft and periods of 19 to 21 seconds. The wind picks up to a moderate breeze from the NW. It’s still cross-shore, so it’s rideable, but it won’t be as clean as Monday.

The next week, from July 27th through July 30th, is much the same story: moderate-sized SW groundswell (3ft to 4ft) with long periods, but the wind is a moderate to fresh breeze from the NW. It’s cross-shore and a bit lumpy.

Then we hit a dry spell. From July 31st through August 2nd, the swell drops to nothing useful – 2ft to 2ft. The wind is strong and offshore, but there’s just no wave to work with.

Finally, on August 3rd, we get a big spike. Monday afternoon rolls in with a massive 12ft swell from the NW. The wind is offshore and clean, but that’s too big for State Line. It’s a pure expert-only situation. The same goes for Tuesday, August 4th, with another 12ft NW swell and glassy conditions in the afternoon. Again, that’s a “too big” call for this break.

So, to wrap it up: the best bet on offer is Monday, July 20th, with clean, glassy head-high waves. The rest of the window is either small, windy, or simply too big. Get out there for that Monday.

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.
