The Lowdown
Alright, Rusty here again. Let’s break down the same outlook but in feet and knots for the imperial crew.
Straight up, this is going to be a long, quiet stretch for L Jetty. We’re looking at a big dry spell with very few windows worth getting wet for.
Right from the start, nothing to get excited about. From now until the 3rd of September, the surf is mostly tiny and messy. Waves are around 1ft to 3ft, but the wind is all over the place – cross-onshore, onshore, and generally choppy. The combined swell energy is weak, sitting between 21 and 107 (moderate energy on the afternoon of the 2nd). For a beach and jetty setup, this is just not happening. A couple of glassy moments on the morning of the 1st and the afternoon of the 31st of August, but the waves are too small to bother. Not worth wetting the suit.
The first real chance comes Thursday, the 3rd of September. The morning kicks off with a clean offshore wind from the west at around 11 knots, and we see waves around 3ft from the southeast with a short 6 second period. The combined swell energy is still only moderate at 87, but the conditions are clean. It’s surfable, but very ordinary. The afternoon holds that offshore wind from the WNW, though the swell drops back to 3ft. This is the best of a very quiet bunch, but it’s for high intermediates and above. Beginners will find it too weak.
Then another long gap. From the 4th of September right through to the 6th, it’s back to tiny surf (around 1ft) and clean but weak conditions. The 7th of September shows a slight uptick – we get a 3ft swell from the SSE with a 6 second period. The wind is light and offshore from the north on the morning, and glassy in the afternoon. The combined energy is still just moderate at 71 to 69. It’s surfable, but again, ordinary.
The 8th and 9th of September see a bit more energy but with poor winds. The 9th is notable for the swell period jumping to 12 seconds, which is a longer period groundswell, coming from the southeast. The combined energy hits 170 (moderate energy), but the wind is cross-shore from the south, creating a slight chop. That longer period means better shaped waves, but at a beach and jetty break like L Jetty, that longer period can make it break a bit straight. Still, it’s the best-looking swell of the whole period. If you’re an experienced surfer, this might be the one to circle on your calendar. The morning of the 11th of September also sees a clean offshore wind from the west, but the swell is tiny again at 2ft.
For the rest of the second week, it’s more of the same – small, weak, and mostly wind-affected. There’s nothing here for beginners, and even experienced surfers will be scratching for a proper wave.
The Standout: If you’re really jonesing, the 9th of September morning offers the best combination of swell size (2ft) and period (12 seconds) and moderate energy (170), but you’ll have to deal with a cross-shore wind. The 3rd of September is your cleanest bet, but the swell is small.
Honestly, this is looking like a kite surfer’s spell more than a paddle surfer’s paradise. Conditions are generally too small and choppy for proper surfing. Stay tuned, though – forecasts change.

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.
