The Lowdown
Alright, this is Rusty.
Let's talk about L Jetty. The next couple of weeks are going to be a real mixed bag, with a big fat zero on the surf-o-meter for a good long while before we finally see a pulse of energy. We've got a dry spell first, then a bit of a stormy period, and then maybe, just maybe, some light at the end of the tunnel.
So, right now, it's looking pretty bleak. From Monday the 14th right through to Sunday the 20th, it's a total bust. We're talking flatness or tiny, weak little lines with no push. The swell height barely scrapes 1ft to 0.7ft for most of that time, and the combined energy is way down in the weak range (14 to 45). The wind is a constant issue, either onshore or cross-onshore, making things messy. There are a few moments of glassy conditions early on Wednesday the 16th morning and again on Friday the 18th morning, but with swells of only 1ft and periods of 5 to 7 seconds, there's just nothing to ride. Honestly, you'd be better off finding a lake. That's a solid 7-day drought of surf.
Then we hit a change. From Monday the 21st through Wednesday the 23rd, the swell really picks up, but it's ugly. We're looking at a building swell, hitting 7ft on Wednesday the 23rd morning, with combined energy climbing into the strong range (323 to 645). The problem? It's coming from the east and east-southeast with a short period of 7-8 seconds, and the wind is straight onshore at 12-19 mph. This is a junky, blown-out mess. For a beach and jetty setup like this, that's kite-surfing conditions, not paddle-surfing conditions. The size alone makes it a no-go for beginners, and the wind ruins it for everyone else.
Finally, things start to look up a little. Thursday the 24th is the one to circle. The morning brings a 4ft swell from the east (9-second period) with a light offshore wind from the west-southwest. That's clean. The afternoon gets even better with a glassy 4ft swell from the east. The combined energy is moderate (282 and 214). This is finally something you can work with, and the first real standout of the outlook. It's not epic, but after a week and a half of nothing or junk, this is a solid, clean, intermediate-level wave.
After that, things drop off again. Friday the 25th is smaller and clean in the morning, but the rest of the weekend into the next week looks pretty ordinary. The swell stays below 3ft, and the wind is all over the place. There are a few more glassy moments, like Saturday the 26th afternoon and Monday the 28th afternoon, but the wave energy is weak. The 29th of September might give us a clean little knee-high wave with an offshore breeze in the morning, but it's nothing to get excited about.
So the clear winner here is Thursday the 24th. That's your window. For everything else, either stay home or pick up another hobby for a bit.
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.
