The Lowdown
Alright, Rusty here. Let’s break down L Jetty for the next couple of weeks.
First off, it’s a flat spell to start. For the first 5 days, you’re looking at tiny bumps from 0.2 feet to 0.7 feet, with combined wave energy mostly in the teens (that’s weak). Winds are messy—cross, cross-on, or onshore—keeping things choppy. The water temp anomaly is 3°F warmer than usual, so the water is noticeably warm for this time of year. Not much to ride.
Sunday the 16th afternoon brings a sudden jump: 2 feet swell from the south, combined energy of 141 (decent), with clean cross-off winds. Not a classic, but probably the best of the first week. Monday the 17th morning has 0.9 feet from the S/SE with clean winds—still small but surfable.
The real event comes way out, on Thursday the 27th of August. Morning swell hits 2 feet from the E/ENE with 308 energy (strong), and afternoon pushes 2 feet from the East at 382 energy (strong). That’s the biggest swell of the run. Problem is, the wind is cross-on and onshore, making it choppy. With a period of 7 seconds, it’s short-period wind swell. At 2 feet, it’s fine for most, but the onshore wind will kill the shape. Friday the 28th holds at 1 feet from the East, but again onshore. This setup looks more suited to kite surfing than proper paddling.
Best bets: Sunday the 16th afternoon is your near-term call—clean and moderate energy. For the long-range, Thursday the 27th has the size but needs a wind shift. L Jetty sees crowds often, so be ready to share. It’s a lean outlook with a couple of moments that might just work.
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.
