The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ for L Jetty over the next couple of weeks.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a long, dry spell with very little to get excited about. The forecast is almost completely blank on quality surf for the first several days, and honestly, it doesn’t really turn on properly until the very end of the month. The water temp is sitting at 73°, which is about 0.9° above normal, so nothing wild there – just a standard warm summer bath.
The first real glimmer of hope doesn’t come until Sunday morning, July 19th. We’ve got a tiny 3ft swell from the SSE, but the period is a short 7 seconds, so it’s pretty weak. The combined energy is only 94, which is feeble. The wind is a cross-offshore from the NW, which will keep the surface clean, but honestly, the waves are just “surfable” at best. It’s not going to be memorable.
The rest of the first week and into the second is more of the same – tiny, weak, short-period slop. We see a bit of a bump from the SSE on Wednesday morning, July 22nd, with 4ft and a 9-second period, and the combined energy jumps to 237, which is moderate. But the wind is a strong 22 mph cross-offshore from the SSW. That’s a lot of wind, and it’ll be a battle to find a clean wave. For a beach/jetty setup, that’s more of a windy, messy day than a good surf day. It’s gonna be a tough paddle.
There’s a gap of several days with no real recommendation until Sunday, July 26th, when the wind finally swings offshore from the W again. The swell is still small, at 2ft from the ESE, with a period of 7 seconds and combined energy of 59. The conditions are clean, but it’s still just “surfable” – not a standout by any stretch.
If you look closely at the very end of the forecast, Monday afternoon, July 27th, offers a brief moment of calm with glassy conditions from the NNE at 3 mph. The swell is a tiny 2ft from the S with a 5-second period – that’s basically flat. It’s a pretty sight, but not a wave you’d drive for.
So, the honest truth? There’s no standout swell in this 16-day window. The best option is probably the Sunday morning, July 19th, for the cleanest conditions, but you’ll be surfing small, weak waves. If you’re a beginner, that 4ft on July 22nd might be a bit too much, especially with the wind. For everyone else, it’s a waiting game. The forecast can change, but right now, it’s a pretty quiet run.
Keep your eyes on the horizon, and don’t sell your board just yet.

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.
