The Lowdown
Alright, Rusty here. Let’s break it down.
Honestly, the next week and a half is pretty bleak around L Jetty. The first surf worth even talking about doesn’t show up until Sunday the 23rd, and that’s a marginal call.
From Tuesday the 18th right through Saturday the 22nd, it’s all small, choppy, and weak. The combined wave energy is pitiful, mostly under 50. Forget it.
Sunday the 23rd, a small 2ft swell from the east with a short 6 second period, but the wind goes light offshore from the west in the morning. It’s clean, and that’s enough to give it a 1 out of 10. A log session if you’re desperate.
The one to circle is Monday the 31st of August, over a week away. The morning shows a solid 6ft swell from the east, with combined energy at 290, so there’s some real grunt. The wind is light offshore from the west-northwest, making for clean waves. The short period (6 seconds) will make them a bit fat, but that energy will push through. This one is best for more experienced surfers as 6ft is getting chunky. By afternoon, the wind switches onshore and it blows out, so be on it early.
A few other mornings, like Friday the 28th and Saturday the 29th, have offshore winds and clean conditions, but the swell is tiny, around 2ft, and the energy is low (59-174). Just a grovel.
Inconsistent is the name of the game here. That Monday the 31st morning is the one real standout, but it’s a long way out, so keep checking back.
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.
