The Lowdown
Alright, Rusty here again. Let's break this down in feet and miles.
It’s been flat and quiet, and that’s the story for the first week or so. From Sunday the 30th of August well into the first week of September, there’s a big gap of nothing worth chasing. Tiny waves and poor conditions are the norm.
The first real chance to get wet comes on Monday the 7th of September. 38 Line is showing a clean 6ft swell from the NNE, with the wind turning glassy in the afternoon and a light offshore from the NNW. The energy is moderate at 354. This is a proper standout for the whole outlook – nice and clean for intermediate surfers. Water temp is about average for the season.
Tuesday the 8th drops back to smaller 3ft waves and glassy conditions, but it’s nothing special.
Now, mark your calendar for Sunday the 13th of September. By afternoon, we’ve got a 7ft north-east swell with clean offshore winds from the west, energy at 396 (moderate-strong). That’s a solid session. But the real big one is Monday the 14th of September – 38 Line is looking at an 8ft east-north-east swell, clean offshore west winds, and a strong energy reading of 785. This is the best of the bunch. It’s a big, powerful swell, so this is for experts only. Beginners should sit this one out. Crowds are never a problem here.
So, first week is a dud. Second week has a couple of good clean days, but the standout is that Monday the 14th. It’s a long way out, so don’t lock it in just yet, but it’s looking promising.
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.
