The Lowdown
Alright folks, Rusty here. Let's have a look at what L Jetty has got cookin' for us over the next couple of weeks.
Right off the bat, I gotta be straight with ya: this is a tough run. We're looking at a long, painful stretch of pretty ordinary conditions. For the first twelve days, from Sunday the 13th right through to late on Thursday the 24th, there’s just nothing worth paddling out for. We've got a lot of onshore and cross-offshore winds, mostly from the north and east, keeping things bumpy and messy. Swell heights are tiny, mostly under 3 feet, and the energy is weak – we're talking combined energy values barely cracking 100 (like 58 to 16), so it's mostly small, weak, and wind-affected slop. It’s a real dry spell for any kind of decent surf.
Now, there is a glimmer of hope as we head into the final weekend of September. Things start to look a bit more interesting on Friday the 25th. The Friday afternoon session might be the first real chance to get wet. The wind is set to go glassy from the ENE at just 3 mph, which is a massive positive. We’ll see a small 4 ft swell from the ESE, but with a short period of 5 seconds, it won't have much push. The combined energy is a low 66, so it’s not powerful, but with those clean, glassy conditions, it might just offer a few fun, weak little waves for a grovel session.
Saturday the 26th is where we might see the best of the window. The morning kicks off with a light offshore breeze from the WNW at 9 mph, and that’s perfect for cleaning up the lines. Swell bumps up a touch to 2 ft from the ESE, but the period jumps to 9 seconds, giving it a bit more shape. The combined energy is a moderate 115, so there’s some actual push behind it. Saturday afternoon looks even better with a 3 ft swell from the E, 9-second period, and a moderate 158 combined energy. The wind stays cross-offshore, keeping things clean. This is the standout session for the whole outlook. L Jetty is a beach/jetty setup, so with a longer period swell like that (9-10 seconds), it can get a bit straight, but with the offshore wind and clean conditions, it should offer some fun, workable lines.
Sunday the 27th continues the better trend. Both the morning and afternoon see light offshore or cross-offshore winds from the west, with a 3 ft ESE swell holding a nice 9-10 second period. Combined energy sits around 147-157, which is moderate and promising. The water temp is sitting at a very unusual 74°, which is 5° warmer than average for this time of year. It’s gonna feel like a warm bath out there.
So, to sum it up: a long, quiet first 12 days, then a late burst of hope. Friday the 25th afternoon is your first chance for a glassy grovel, but the real standout is Saturday the 26th, especially the afternoon, with clean conditions and the best combo of swell size and energy. Sunday the 27th is also solid. After that, it looks like we’re back to small, onshore slop. It’s been a lean run, but it tends not to stay this poor forever. Keep an eye on it.
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.
L Jetty is 3 km (2 miles) from Asbury Park. If you plan a vacation in New Jersey, look for hotels and other accommodation in Asbury Park. Asbury Park has rooms for a wide range of budgets as well as car hire and transport links.
