The Lowdown
Alright, folks, Rusty here. Let’s be straight with you – this outlook for L Jetty is a tough one. We’re looking at a long stretch of small, messy conditions with no real standout sessions. The water is much warmer than usual for the time of year at 78°, which is a bit of a talking point, but doesn’t help the waves. There’s a gap of poor surf from the start until at least the end of the month, so don’t get your hopes up.
For the morning of Thursday the 20th, we’ve got a tiny 1ft SE swell with a period of 9 seconds, but it’s glassy with a light ENE breeze at 3 mph. The combined energy is weak (23), so it’s barely a ripple. That afternoon turns to light rain and a cross-on wind, making it even less appealing. Friday the 21st is a write-off with 3ft ENE windswell but a nasty 12 mph cross-on breeze and a short 5-second period – that’s choppy junk. The weekend doesn’t offer any relief. Saturday the 22nd stays poor with rain and onshore winds. Sunday the 23rd has a tiny 0.7ft SE groundswell with a long 13-second period, and it’s clean with a cross-off breeze, but it’s too tiny to ride.
Monday the 24th and Tuesday the 25th are clean but tiny, with offshore winds, and the swell is under 2ft. The energy is still weak. The pattern of small, onshore windswell or tiny clean waves continues right through the end of the month and into early September. By Friday the 4th of September, we see a clean cross-off breeze with 2ft E swell, but the period is only 8 seconds and the energy is still weak (71). For the whole 16 days, the best you can hope for is a clean but tiny wave on a light wind day – really only for a longboard or a paddle. There’s nothing here for anyone looking for a proper surf. The combined energy never gets above 97, staying firmly in the weak range. If it wasn’t for the clean windows, you’d be better off kiting here.
Honestly, this is a flat spell. Forecasts can change, but right now, it’s a blank run that’s pretty normal for this spot when the swell window shuts down.
Rusty.

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