The Lowdown
Alright folks, Rusty here. Looks like we’ve got a bit of a dry spell ahead at L Jetty. The next two weeks are looking pretty grim for a proper paddle session, so I’ll give it to you straight.
The pattern for the next 16 days is mostly small, weak, and messy. We’re looking at a long stretch of poor surf conditions, with only a few days offering anything worth mentioning, and even then, it’s a real struggle. You’ll see a gap of about four days of truly bad surf right off the bat, with nothing to get excited about until the second week.
The first real sniff of something happens on the morning of Monday, August 24th. The wind swings offshore from the west at 15 mph, which is a major positive, cleaning things right up. But the swell is a tiny 1.0 ft from the ESE, with a long period of 12 seconds. That long period groundswell is full of energy, but for a beach/jetty setup like L Jetty, it’ll likely break too straight and won’t have the size to do much. The combined energy is weak (51), so it’s more of a look-see than a go-out. The offshore wind is a tease, but it’s just too small.
We then slide into another long gap of no real hope until the very end of the forecast. The only standout, and I mean the *only* one, is on Thursday, September 3rd, in the afternoon. The swell jumps to 5 ft from the east, with a moderate period of 9 seconds. The combined energy hits a strong 647, which is a proper pulse of power. The wind is light cross-onshore from the ENE at 6 mph, which is manageable. But the file says it’s only marginal surf due to questionable tide conditions. This is as good as it gets, but it’s a stretch. At 5 ft, it’s getting a bit much for beginners, but it’s not in the expert-only zone. The crowd profile says L Jetty gets “often” crowded, so if this pulse lines up, expect company.
Overall, it’s a bleak outlook. The water is about 78°F, which is 5°F warmer than normal, so at least you won’t freeze while you’re sitting there waiting for a wave. But for surfing, there’s nothing to get your heart racing. The beach/jetty setup with the onshore and cross-onshore winds we’re seeing for most of the period would actually be more interesting for kite surfing than paddle surfing.
Stay patient, and don’t sell your board just yet. 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.
