The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for L Jetty over the next couple of weeks.
It’s gonna be a real test of patience. The next four days are a write-off. We’ve got a bit of swell, but it’s short-period junk, mostly under 3ft, and the wind is all over the shop – cross, cross-on, and cross-off. It’s just messy, with poor conditions. The combined energy is weak, barely cracking 50. You’d be wasting your time.
The first real glimmer of hope comes on Wednesday the 22nd of July. The morning sees a clean 5ft SSE swell, with a moderate offshore wind from the west. That’s the good stuff. The combined energy jumps to 308 (moderate), and the water is a touch warmer than normal at 74°. The afternoon gets even better, with the swell bumping up to 6ft from the south, a light offshore breeze, and the energy cranking up to 753 (strong). This is a proper window of clean, punchy waves. It’s not massive, but it’s the best we’re going to see. The 9-second period means it’s a local windswell, so it’ll be a bit sectiony, but with that offshore wind, L Jetty should be fun.
After that, it’s back to the holding pattern. The swell drops off, the wind goes onshore or cross-shore again, and the energy readings are pitiful (mostly under 100). We’re looking at days of flat, choppy, or blown-out conditions. There’s a tiny blip of clean conditions on the 26th morning, but the swell is only 1ft – not enough to bother with.
Right at the end of the run, on Friday the 31st of July, we see a bit of a pulse. The morning brings 4ft of S swell, and the afternoon pushes it to 4ft, with combined energy hitting 182 and 235. That’s moderate energy, but it’s coming in with a strong cross-onshore wind from the NE. It’ll be a choppy, lumpy mess, not worth the paddle.
The standout is undoubtedly Wednesday the 22nd of July. The morning and afternoon are both clean, but the afternoon is the pick of the whole 16 days. That 6ft S swell with light offshore wind is your best chance at a decent session. The break is `fairly consistent` and crowds are `often`, so expect company, but for the conditions on offer, it’ll be worth it.
Stay keen, and wait for that Wednesday.
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.
