The Lowdown
Alright, Rusty here again, but in feet and miles for those who think that way.
It’s a slow start at L Jetty. Monday the 20th and Tuesday the 21st are all small, weak, and blown out. Tiny waves, onshore wind, and energy levels that barely register. Not worth getting wet.
First real hope comes Wednesday morning the 22nd. Swell hits 6ft from the S, 8 seconds, with a SW cross-offshore breeze. The combined energy is 641 (moderate), and it’s clean. That afternoon it gets even better: 7ft from the S, 8 seconds, and a solid offshore W wind at 12 mph. Energy jumps to 817 (strong). This is the best window of the whole outlook. Clean, punchy, and good for anyone who’s intermediate or better. Go that afternoon.
After that, it dries up fast. Thursday the 23rd has some clean 3ft waves in the morning, but the energy is weak (160). From Friday the 24th through the end of July it’s mostly small, onshore, and poor. A long stretch of nothing much.
There’s a little bump on Sunday the 2nd of August: 5ft from the S, 7 seconds, cross-shore, with energy at 226 (moderate). It’s only marginal. Then Monday the 3rd of August afternoon looks interesting: 4ft from the S, 7 seconds, with glassy conditions and a light WNW wind at 3 mph. Energy is 227 (moderate). That’s a clean, small session for the second week, but it’s not the standout Wednesday the 22nd is.
Water temp on Monday the 20th is 75°, which is a touch warmer than usual for this time of year.
Bottom line: Wednesday the 22nd afternoon is the call. The rest is mostly small and messy, with a few clean moments but nothing to write home about.
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.
