The Lowdown
Alright, Rusty here. Let’s get into what’s cookin’ at Jetty.
I won’t sugarcoat it: this forecast is a long, flat, choppy stretch. The first bit of hope doesn’t show up until Wednesday, the 5th of August, and before that it’s a wasteland. The whole sixteen days is a battle against the wind.
The one session that’s worth pulling your wetsuit on for is the Wednesday morning, the 5th of August. The Jetty breakwater is showing a small SSE swell of about 4 feet, but with a short period. The wind is the big story here – a clean cross-offshore breeze from the WNW. That’s a rare treat for this spot. The water temp is about 73°, which is normal for the season. The combined energy is weak, sittin’ around 146, so don’t expect any grunt, but it’ll be the cleanest waves you’ll see all week. This spot breaks very consistently, so you’ll find waves, but with the crowds, you might have to share.
After that, it’s a tough watch. The rest of the week and all of the second week are plagued by cross-onshore and cross-shore winds, with tiny swell heights barely reaching 3 feet. There are a couple of moments of glassy or offshore wind around the 11th and 12th of August, but the swell is a pathetic 2 feet or less with almost no energy. It’s the kind of day that breaks your heart more than it gives you a ride.
For this setup, with the onshore wind and weak, short-period swell, it’s honestly a better bet for the kite surfers than the paddle crew. There’s just not enough clean face or power to get excited about a surfboard.
Rusty out.

Information about the Jetty Surf forecast
The above surf forecast table for Jetty provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jetty can be found by selecting the local surf guide option on the grey menu. Our 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 (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 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.
Jetty is 15 km (9 miles) from Mastic. If you plan a vacation in Long Island New York, look for hotels and other accommodation in Mastic. Mastic has rooms for a wide range of budgets as well as car hire and transport links.
