The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s coming up for 38 Line.

Right off the bat, we’ve got a bit of a flat spell. The first few days are pretty much a write-off, with tiny, messy waves and poor conditions. Thursday the 27th through to the end of the month are all small, weak, and not worth getting excited about. The water temp is sitting at 80° which is much warmer than normal for this time of year, so that’s a nice bonus if you’re just floating around.

Things start to look a little more interesting on Saturday the 29th morning. We get a small 3 ft swell from the ESE with a bit of a cross-offshore breeze from the NW, keeping things clean. Combined swell energy is weak at 55, but it’s surfable. It’s not going to blow your mind, but it’s a start.

Sunday the 30th morning is glassy, with light NE winds and a 3 ft NE swell. The energy is still weak at 88, but it’s clean and the conditions are good for a small-wave session. Nothing to drive hours for, but a pleasant paddle.

Now, hold on to your boards, because the second week is where the real action is. The standout period is around the 7th of September. Monday the 7th morning is the pick of the bunch. We’ve got a solid 7 ft groundswell from the ENE, with a period of 10 seconds, combined energy of 1020 – that’s moderate to strong. The wind is dead calm, glassy as it gets. This is for experienced surfers only – 7 ft is big, powerful, and will be a handful. It’s going to be a proper session for those who know what they’re doing.

The build-up to that is significant. Saturday the 5th afternoon sees a 10 ft swell from the ENE, but it’s predicted to be too big for this break. The energy is huge at 1156. Sunday the 6th is even bigger, with a 13 ft swell and 3930 energy – that’s strong to very strong wave energy. That’s a big, powerful ocean and not for the faint-hearted.

After the Monday peak, the swell drops but conditions remain good. Tuesday the 8th morning is glassy again with a 4 ft ENE swell and 313 energy – clean and manageable. Not a standout, but a solid option.

The tail end of the forecast, Friday the 11th morning, looks promising with a 7 ft ENE swell and clean cross-offshore winds from the NW. Energy is 550 – moderate. That’s another one for the experienced crew.

Bottom line: The first week is a snooze. The second week has a clear highlight: Monday the 7th of September morning – glassy, 7 ft ENE groundswell, clean, and powerful. That’s your best bet, but it’s for experts only. The sets will have some good energy and the long period will mean longer waits between waves. The crowds here are never a problem, so you’ll have plenty of room.

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.
