The Lowdown
Alright, Rusty here. Let's be straight with you. We're looking at a long, 16-day forecast for 38 Line, and I'm not gonna sugarcoat it.
Honestly, for the first two weeks of this outlook, it's flat. I mean, properly flat. We're staring down the barrel of a massive drought from now all the way through to Thursday, August 7th. There's barely a ripple in sight. The odd bit of knee-high slop shows up, but it's always called "poor surf conditions," so you aren't missing a thing. The combined energy is stuck in the low single digits or zeros for days on end. It's a tough run for this spot, and a blank stretch this long can happen.
But here's the kicker, and it's a wild one. The whole pattern flips on its head for Saturday, August 8th. The forecast is pointing to a huge pulse of swell. We're talking a solid 12ft to 13ft of swell from the NE with a solid 9 to 11-second period. That's a massive jump from nothing. The combined energy shoots up to a staggering 1925 on Saturday morning and then peaks at 7259. That is some serious, proper ocean energy.
Now, here's the catch, and I have to be honest with you. For 38 Line, that size is just too big. The forecast literally says the swell is predicted to be too big for this break. For a wave that size, you're looking at an expert-only scenario, and even then, it might just be unsurfable closeouts. The wind on Saturday morning is light and offshore from the NNW, which would make for clean waves, but the power would be intimidating.
That big Monday, August 8th, swell is the only real standout, and it's more of a spectacle than a recommendation for a paddle session. If you're a hellman on a big gun, you might find a sneaky corner, but for 99% of us, it's a watch-from-the-beach day.
So, the brutal truth: two weeks of nothing, then one day of way too much. The long-range promise of that swell is exciting, but it's a cruel tease for this spot.
Rusty.

Information about the 38 Line Surf forecast
The above surf forecast table for 38 Line provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 38 Line can be found by selecting the local surf guide option on the grey menu. Our 38 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 (38 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 38 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.
