The Lowdown

Alright folks, Rusty here. Let’s have a proper look at the next couple of weeks. I’ll be straight with you – it’s a lean stretch for L Jetty. We’re looking at a long, quiet spell with hardly any proper surf, so patience is the name of the game.

The first week is pretty much a write-off. From Friday the 17th right through to Tuesday the 22nd, it’s flat and messy. Waves are tiny, the wind is mostly cross or onshore, and the energy is weak. The water temperature is sitting at 74°, which is a touch warmer than normal for this time of year, so at least a paddle won’t give you the chills.

Wednesday the 22nd afternoon is where we finally see a flicker of life. The swell bumps up to 3ft from the SSE, with a moderate offshore wind from the W keeping things clean. The combined energy jumps to 170 (moderate), which is the best we’ll see for a while. It’s not big, but it’s surfable and clean – a small window for a slow, fun session.

The rest of the week stays weak. Thursday morning offers a tiny 2ft with clean conditions, but the energy is still low (103). Saturday the 25th morning is glassy with a 2ft swell, but it’s gutless. The following days are more of the same – small, weak, and mostly cross-shore. The swell direction is all over the place, which doesn’t help.

Looking further out, the last day of July (Friday the 31st) gives us another glassy morning with a 1ft groundswell from ESE (9-second period). It’s clean, but you’ll be hunting for knee-high bumps. The energy is still weak (53). Not a standout, just a chance to get wet.

If I had to pick the best on offer, it’s Wednesday the 22nd afternoon. That 3ft clean swell with offshore wind is the only real window for something rideable. Beyond that, it’s pretty grim. The crowds are often around here, but with this lack of surf, the lineup will be quiet.

To be honest, with this setup, the beach might be more interesting for kite surfing than paddle surfing. But stick with it – forecasts can change.

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.
