The Lowdown
Alright, this is Rusty. Let’s be straight with you — the next 16 days at L Jetty are a tough watch. There’s really nothing on the table that’s going to get you stoked. The whole run is a flat, weak, and messy affair, with only a couple of brief windows where you might find something to ride, but nothing worth calling a standout.
The forecast starts with a gap. From Saturday the 15th through to Monday the 17th, it’s all tiny, choppy, or cross-shore junk. Swell heights barely reach 2 ft, periods are short, and the combined energy is weak, sitting around 17 to 93 — that’s barely a ripple. The wind is mostly cross or cross-onshore, and the water is much warmer than usual for this time of year at 78°, which is a notable anomaly of 5° warmer.
Then Monday the 17th morning offers a little hope. The wind swings offshore from the west at 9 mph, and the swell picks up to 3 ft from the SSE, with a period of 6 seconds. The combined energy jumps to 57 (moderate), and the conditions are clean. It’s surfable, but it’s very ordinary. The afternoon stays clean with lighter offshore wind, but the swell is still weak and short-period. This is about as good as it gets — and that’s not saying much.
From Tuesday the 18th right through to the end of the month, it’s all poor. Swell heights bounce between 0.6 ft and 4 ft, but the periods are short, often 5 to 7 seconds, and the wind is mostly onshore or cross-onshore, creating choppy, messy conditions. The combined energy rarely climbs above 100, only hitting 104 on Saturday the 22nd morning, but that’s onshore wind ruining it. There’s nothing here that’s going to deliver a wave you’ll remember.
The only thing close to interesting is Monday the 24th and Tuesday the 25th, when the period stretches to 11-12 seconds, and the wind goes cross-off or light, leaving clean surfaces. But the swell is tiny — 0.6 ft to 1 ft — so you’re looking at barely a knee-high ripple. The combined energy is weak, in the 30s. Not worth the drive.
Bottom line: this is a 16-day stretch with no real surf. The offshore wind on Monday the 17th is the closest you’ll get to a surfable moment, but it’s small and weak. For a beach/jetty setup like L Jetty, this kind of blank run happens. Don’t stress — forecasts can change, and it won’t stay this flat forever.

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.
