The Lowdown
Alright crew, Rusty here again, switching over for you imperial guys. Let’s break down L Jetty for the next couple weeks.
Straight up, this is looking like a tough period. For L Jetty, there’s almost nothing worth paddling out for in the first week. Starting Wednesday, July 15th, it’s tiny weak surf – like 1ft out of the south with a 5-second period and only 16 combined energy. The water is 72°, right on average for the time of year, but the waves are a total bust. That pattern of small, weak south swell just drags on through Saturday, July 18th. Nothing scores above a zero.
We get a little bump on Sunday the 19th – the swell hits 3ft from the south-southeast with a clean offshore breeze, but the period is a short 7 seconds and energy is still weak at 89. It’s surfable, but only just.
Now, Monday morning, July 20th – this is the highlight. Glassy conditions. The swell is 3ft from the south-southeast with a 9-second period and combined energy of 91. It’s small, but those glassy winds are a major positive. You’ll find clean little lines at L Jetty. The afternoon gets wrecked by a 25 km/h cross-shore, so that morning window is it. It’s still just “surfable but ordinary,” but it’s the best we’ve got.
Next real chance is Sunday, July 26th in the afternoon. Swell is 3ft from the south-southeast, short period at 8 seconds, but energy is moderate at 124 and the wind is offshore from the west-northwest. Clean waves again, but nothing special. Then Monday, July 27th morning is glassy with a 2ft south-southeast swell – tiny and weak.
For the whole 16 days, there’s no true gold here. The glassy Monday (July 20th) and that clean Sunday afternoon (July 26th) are your only real windows. The rest is mostly flat, choppy, or onshore slop. On those windy days, the setup looks way more fun for kiteboarding than surfing. For the wave riders, it’s a dry spell.
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.
