The Lowdown
Alright folks, Rusty here with the lowdown on L-Jetty. It’s looking like a lean couple of weeks on the surf front.
We’ve got a long dry spell with nothing worth paddling out for until Monday the 17th. The first sign of life is Monday afternoon with a tiny 3ft SSE swell, but the wind goes glassy out of the WSW. That glass is your only friend here, making it just about rideable. The energy is weak (54), so it’s small ball stuff.
Your real best bet comes on Sunday the 23rd. The morning brings a 3ft S swell with clean cross-offshore winds from the WSW, carrying a bit more energy (74). It stays clean through the afternoon as it drops to 2ft. It’s small, but it’s clean and manageable for an intermediate surfer. That’s your session.
The rest of the run is a mix of onshore chop and flat spells. On Friday the 28th of August, we see the swell push up to a solid 3ft from the ENE, with the energy finally climbing into the moderate range (107). But the wind is a mess – cross-onshore – so it’s going to be lumpy and no good.
To sum it up, Sunday the 23rd is the only real standout. It won't blow your mind, but the clean conditions make it your best shot. L-Jetty can get a crowd, but on a small, clean day like that, it might be worth the gamble.
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.
