The Lowdown
Yo, it’s Rusty. Let’s get real about this one. We’ve got a 16-day window, but honestly, the first week is a near washout. There’s only one true standout session, and it’s a short-lived window. After that, the forecast goes flat and messy again, so don’t hold your breath.
The only spot on the radar is L Jetty, a beach/jetty setup. For the first week, the swell is tiny and the wind is trash. Most days are cross-shore or onshore, with heights barely scraping 3 ft and periods around 4 to 7 seconds. That’s weak, short-period junk. The combined energy is mostly in the 20 to 50 range, which is pretty weak. Nothing to get excited about. The water temp is sitting at 74°, which is a touch warmer than normal for this time of year, so you won’t need a thick wetsuit.
But then, on Wednesday morning, July 22nd, things finally line up. We get a clean 4 ft swell from the SSE with an 8-second period, and the wind turns offshore from the west at 12 mph. The combined energy jumps to 221 (moderate), and the wave comment says “expect good surf conditions.” That’s our window. The swell direction is a bit wide of the optimum ESE, but it’s still a solid call. The break is exposed, and it’s fairly consistent. Just be aware of the crowds – they’re often there, so you’ll have company. It’s a moderate offshore and clean, so the waves will hold shape. That Wednesday morning session is the standout.
By Wednesday afternoon, the swell bumps up to 6 ft with energy at 554, but the wind stays offshore. It’s still clean, but the bigger size (over 5 ft) means it’s getting borderline for beginners. The afternoon could be a second option if you’re intermediate or better.
Then, from Thursday, July 23rd onward, it’s back to poor conditions. The wind goes cross or cross-on, and the swell drops or stays messy. There’s a long gap of over a week with no decent surf. The second week (late July into early August) has some 5 ft to 6 ft swell, but it’s all onshore or cross-onshore wind, weak periods (6 to 7 seconds), and the energy is scattered. The wave comments are all “poor surf conditions.” Nothing worth paddling out for.
So, bottom line: if you want a wave, your only real shot is the morning of Wednesday, July 22nd at L Jetty. After that, it’s a long dry spell. For the rest of the time, the setup is more interesting for kite surfing than paddle surfing, given the onshore wind and lumpy chop. But don’t give up hope – forecasts can change, and a run like this tends not to stay poor for long.
Stay salty.
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.
