The Lowdown
Alright folks, Rusty here. It’s a bleak one for L Jetty.
Right off the bat, we’re staring at a long stretch of tiny, weak surf. The water temp is 72°, which is normal for the season, so no surprises there.
The first few days are a total bust. From Tuesday the 14th through the week, we’ve got nothing but knee-high slop with combined swell energy barely registering (20-37). You’re better off staying home.
Things get a tiny bit interesting on Sunday the 19th afternoon, but it’s still just “surfable” with energy at 74. The only real hope in the whole 16 days is the afternoon of Wednesday the 22nd. The swell jumps to 4ft from the SSE, energy hits 363 (moderate), and the wind is light and cross-off from the NW, keeping it clean. That’s your one chance for a proper wave.
After that, it’s back to the small stuff. The rest of the forecast is a mix of weak, messy, and choppy conditions. The 27th afternoon shows a little bump in energy (139), but the swell is tiny and short period.
If you’re going to wet a line, that Wednesday the 22nd afternoon is the only window. The rest is a long, dry spell.

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.
