The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for 38 Line.
First up, we’re staring down a pretty quiet spell. The ocean’s flat for a few days, so don’t bother checking the waves until later in the weekend. This is a bit of a slow start, but the models are hinting at a pulse coming through.
The first real chance to paddle out comes Saturday, August 9th morning. We’re looking at a small 5ft swell from the NNE, but it’s rideable. The wind is a moderate cross-offshore from the NW, keeping things clean. The combined energy is weak (201), so it’s not going to be a world-beater, but for a first hit of the period, it’ll do.
The one standout window is on Thursday, August 13th morning. The swell jumps up to 10ft from the NE, with a lovely long period of 11 seconds, giving it a proper groundswell feel. The combined energy is strong (1763), and the wind is cross-shore from the NNE. That said, 10ft is well into expert territory—this is not for the faint of heart. The long period will make it bend nicely around the reef, but it’s going to be a beast of a paddle and a heavy drop. This is a true big-wave session for the crew with the right board and the right nerve.
A few days later, check Sunday, August 16th morning. The swell drops right back to 3ft from the NE, but it’s glassy. The wind is a light offshore from the NNE, and the combined energy is a paltry 56. It’s small, it’s clean, and it’s a good chance for a longboard or a fun fish if you’re not looking for a thrill.
As we head into the last week of the forecast, the swell fades back to nothing. By Thursday, August 21st, we’re clutching at 2ft from the E, and the energy is a measly 34. The water temp is nothing to write home about, just average for this time of year.
So, to wrap it up: if you’re an expert, your red-letter day is August 13th morning. For everyone else, the most user-friendly surf with clean conditions is the small stuff on August 16th morning. Otherwise, it’s a week of waiting and watching.
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.
