The Lowdown
Alright, let’s get real here. We’ve only got one break in the mix from the get-go, and that’s L Jetty. I’ll walk you through what’s on offer.
Right now, Wednesday morning, the ocean’s basically asleep. We’re looking at a tiny 0.3ft swell from the southeast, and while the wind is a clean cross-offshore, the energy is weak (9). The water temp is sitting at a very unusual 75°, which is much warmer than normal for this time of year. But honestly, you’re not gonna be in the water long enough to enjoy it because the surf is poor.
We roll into Thursday morning, and there’s a slight pulse of 3ft swell from the south. The period is a short 6 seconds, so it’s not got any punch, and the energy is still low (56). The wind is offshore from the west, which is a good sign for clean waves, but the quality is described as very ordinary. It’s a marginal window if you’re desperate.
Friday morning sees the swell drop back to 2ft, with a cross-offshore breeze. Again, clean conditions but very small and weak. Friday afternoon turns glassy with a 1ft south-southeast swell, but it’s still poor.
The weekend doesn’t offer any relief. Saturday is tiny and onshore or cross-shore, with no quality. Sunday brings a bit more height, up to 3ft and 4ft, but the period is a shocker—only 4 to 5 seconds (energy 35-87). That’s choppy, wind-affected junk, and there’s a risk of thunderstorms. Not worth your time.
Monday (14th September) through to the end of the forecast is a real drought. The swell stays under 3ft, the period is mostly short to middling, and the winds are either cross-on or cross most of the time. There’s a brief moment on Wednesday morning (16th September) with 3ft and clean cross-offshore wind, but it’s still very ordinary and tiny. After that, it’s all poor surf conditions. The energy values rarely get above 50, and when they do, like on Thursday afternoon (17th September) with 3ft and 77 energy, the wind is onshore, so it’s messy.
There’s no standout session in this 16-day window. The swell never gets above 4ft, and the longest period we see is 12 seconds right at the end on 19th September, but that’s attached to a tiny 0.7ft swell. It’s a long run of small, weak, or onshore conditions. For a beach/jetty setup like this, the lack of size and consistent clean windows means the kites might get more out of it than a paddle surfer on most of those afternoons.
It’s a tough run, folks. But that’s the way it can go sometimes. The forecasts can flip, so don’t bin the boards just yet.

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.
