The Lowdown
Alright, let’s talk this one out in feet and miles per hour. L Jetty is on a lean spell, plain and simple. The first week and a half is mostly a bust, with a few tiny bright spots if you’re really jonesing.
Friday the 11th and Saturday the 12th are a total write-off. You’re looking at knee-high slop with bad wind. The water is running at 74°, which is about 4° warmer than it should be this time of year – the ocean’s got a bit of leftover summer warmth, but it’s wasted on this junk. Wave energy is pitiful, around 19 to 26.
Sunday the 13th is the first thing that’s even ridable. We get a 3ft swell out of the SE with a short 6-second period. What saves it is a light offshore wind from the WNW, keeping the surface clean. The energy is still weak at about 56, but you could get a few little peelers on a bigger board. It’s not good, just less bad.
Monday and Tuesday are back to onshore wind and chop. A long dead period follows.
Tuesday the 22nd is when the ocean turns on. The swell builds to 4ft to 5ft from the E and ESE, with 6 to 7-second periods. The energy jumps to 128 and then 190 (combined energy of all swells directed here). Wind is cross-onshore, so it’s chop city, but the size is coming up.
Wednesday the 23rd pushes to 6ft from the E with an 8-second period. The energy is solid at 519 to 552. Still cross-onshore and choppy. A lot of water, but not clean.
Thursday the 24th – here’s the one. Morning sees 7ft E swell, 8-second period, and glassy offshore wind from the WSW. Energy is up to 619. The afternoon gets even better: 8ft from the E, same period, with light cross-offshore wind from the SW. Energy hits 1034. This is the window. It’s big, powerful, and clean. Intermediates, this is your moment. Beginners, this is too much. Crowds are often around, but this size might thin them out a little.
Friday the 25th morning is a beast. 10ft from the E with a 10-second period, energy is a massive 1789. Light cross-offshore wind from the SSW keeps it clean. But the forecast says this is too much for L Jetty. Experts only. The afternoon drops to 8ft but picks up a cross-shore wind, so it’s not as clean.
Saturday the 26th drops to 7ft but onshore wind from the NE ruins it.
So to sum it up: the first 10 days are a write-off with long dry gaps. The one true standout is Thursday the 24th – that 7ft to 8ft E swell with light, clean wind is the session you want. Friday morning is huge and clean, but it’s for the brave ones who know what they’re doing.

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.
