The Lowdown
Alright folks, let’s be honest about what we’re looking at. This forecast is a pretty grim run for a while. We've got a long stretch of tiny, weak surf and a lot of wind from the wrong directions. The first couple of days are totally flat, with maybe a little knee-high bump and plenty of chop. We’re talking a good five days with nothing worth waxing up for. There is one bright spot on Monday the 24th when the wind swings cross-offshore and it goes glassy. It’s only a 2ft south swell, but it’s clean and the energy reads at 91. If you’re jonesing for a surf, that’s your window. It’s not going to be epic, but it will be rideable.
Beyond that, the next week keeps the same theme: small swells, short periods, and a lot of wind. There’s a slightly bigger pulse on Saturday the 22nd afternoon at a bit over 3ft, but it’s onshore and the period is a weak 5 seconds, so it’s going to be a mess. As we head into the last few days of the month, the energy does pick up a little, hitting 137 on the 28th, but it’s still small – around 3ft – and the wind is mostly on or cross. That Friday afternoon though, the wind swings to a clean cross-off, so that’s probably our best bet of the whole run. It’s not the biggest, but it’ll be the cleanest.
For the standout, I’d say Friday the 28th afternoon gets the nod because it’s clean and has a bit more push behind it. Monday the 24th is a close second for the glassy conditions. On top of all that, the water is running well above normal for this time of year, so the warm water is a definite plus. But other than those couple of small windows, this stretch is about being patient. The boards can stay in the garage for a bit. It’s a two-week run of mostly flat, onshore junk. Hang in there.

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.
