The Lowdown

Alright, let’s talk about State Line.

It’s a slow start right now. Tuesday morning is a bit rough – we’ve got a 1.9m NW swell with a cross-on wind, and the water’s sitting at 53°, which is a bit colder than usual for this time of year. By Tuesday afternoon, the wind goes glassy, which is nice, but the swell’s still that same short-period NW windswell – not super exciting.

Wednesday is pretty much a bust. Both morning and afternoon have clean offshore wind, but the swell drops to 1.6m and then 1.2m, and the period is still short. It feels flat and weak. Thursday and Friday are even smaller, with 0.5m to 0.6m swell and cross winds. There’s a long gap of nearly nothing through the rest of the first week.

Now, here are the real standout events. On Sunday afternoon, August 9th, a big pulse of NW swell hits at 3.5m with a short period of 8 seconds. The wind is clean and cross-off, and the wave energy is huge at 1433. That’s too big for this break – only for the experts. Then again on Tuesday, August 11th afternoon, we get another similar pulse: 3.5m NW at 8 seconds, with clean cross-off wind and energy at 1694. Same deal – expert only, and it’s a long-range call so don’t book your flights yet.

The rest of the second week stays mostly small and marginal. There’s a bit of a bump on Saturday, August 15th with a 2.1m NW swell, but the wind is cross-shore and the period is short. The only other real standout is on Wednesday, August 19th afternoon – a big 3.0m NW swell with a short 7-second period and moderate cross-shore wind. The energy is strong at 1143, but again, that’s too big for this spot, only for the brave.

So for a regular surfer, there’s not a whole lot to get excited about. The two big pulses on the 9th and 11th are the only true standouts, and they are serious, expert-only swells. Everything else is small, short period, and mostly messy.

Keep an eye out, forecasts can change.

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.
