The Lowdown

Alright, let’s take a look at what’s shaping up. This is Rusty, and I’ve got to be straight with you – this 16-day stretch looks grim, real grim. There are no standout days, no solid groundswells, just a long, drawn-out nothing-burger. If you’re jonesing for a wave, you’ll be fighting tiny, weak leftovers and mainly onshore junk.

The only spot on the radar is L Jetty, a beach and jetty setup. They’re calling it fairly consistent, but don’t let that fool you. It’s exposed, often crowded, and likes an ESE swell – which we barely get. Water temps are sitting at 73°, a touch warmer than normal for this time of year, but that’s about the only thing that’s not disappointing.

The whole first week is a write-off. Wednesday the 2nd and Thursday the 3rd offer the biggest surf of the whole run, with a 4ft easterly swell and a 3ft easterly swell, but both are short-period windswell (6 seconds), and moderate onshore winds ruin any chance of quality. Combined swell energy is weak to moderate (134 and then 114), just messy and bumpy. Thursday afternoon sees the wind drop to glass, leaving a 2ft wave that’s rideable but ordinary as all get-out – barely a knee-high ripple. Friday the 4th drops to 1ft, then it’s nothing but tiny lumps under 3ft for the next ten days straight.

There’s a long gap of utterly poor surf from the 4th all the way through to the 14th. Days and days of flat to near-flat conditions with weak energy readings in the teens and tens. A few sessions show clean faces from light offshore or cross-off winds, like Thursday afternoon the 3rd, Monday morning the 7th, or Tuesday the 8th, but the swell is so small (1.0ft to 2ft) it’s barely worth paddling out for. Short-period, low energy – just not doing anything.

The one tiny flicker of hope comes on Monday the 14th morning. We get a small clean 2ft swell from the SSE with a cross-off wind. Combined energy is still low (66), but it’s surfable, and the conditions aren’t junk. It’s far from a standout – more like a consolation.

Beyond that, the second week fades into nothing: tiny 0.7ft waves, long-period ESE swell (14 seconds), but it’s just too small to do anything with. The energy is pitiful (29, 32). A long period like that with almost no height is mostly just a flat ocean with a little pulse.

Honestly, if you’re desperate and just want to get wet with a clean little ankle-snatcher, Thursday afternoon the 3rd and Monday morning the 14th are your best shots. But don’t expect any power, shape, or quality. This place looks more interesting for a paddle board or a swim than a surfboard for the next two weeks.

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.
