The Lowdown
Alright folks, Rusty here. Let’s break down what’s ahead for the next couple of weeks. Honestly, it’s a pretty quiet stretch for the most part. There are a few windows where things might just turn on, but you’ll need to pick your moments.
The first real chance to get wet comes on Saturday, 18th July, and it’s a bit of a tease. The swell picks up to 4ft out of the East, with a combined energy of 60. That’s not huge, but what makes it interesting is the glassy wind. Total calm, no wind ripples. That’s a rare treat, and it’ll make for clean, smooth conditions. The waves themselves won’t be world-class, but it’s a surfable window. Water temp is about average for this time of year, nothing wild.
The conditions go a bit messy again after that, with cross-onshore winds and small, weak swell. We’re looking at a few days of nothing special through until the 20th and 21st. On Monday, 21st July, we get a small bump in quality. The wind swings offshore from the West, 12 mph, and the swell holds at 3ft from the SSE, with a period of 7 seconds. Combined energy is 109, so there’s a bit of push. The waves are surfable, but still very ordinary. It’s a session for the keen, not the picky.
Now, the real standout is the afternoon of Sunday, 26th July. That’s the one to circle on the calendar. The swell is 5ft out of the SSE, with a period of 7 seconds, and the combined energy jumps to 315. That’s a solid pulse of energy. The wind is offshore, light from the WNW at 3 mph, and the water is clean. This is the best we’re going to see: a real shot at some proper waves. The swell is big enough to be fun for intermediate and experienced surfers, but at 5ft it’s manageable. The break is L Jetty, which is a beach and jetty setup. It’s exposed and fairly consistent, but crowds can be an issue. With conditions this good, expect it to be busy.
After that, the surf drops off again. The final few days of the forecast see a return to smaller, weaker swell and mostly cross or onshore winds. There’s a brief moment on Tuesday, 28th July morning with glassy conditions and 4ft swell, but it’s nothing to write home about.
So, the clear winner is the 26th. If you can only get out once, make it that Sunday afternoon. The rest is mostly wait-and-watch.
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.
