Gather round, surfers. Rusty here, and I’ve got the lowdown on the local stretch.

Alright, let’s be straight—this is a grim outlook for the next sixteen days. We’re looking at a big, fat blank run with almost nothing in the way of decent surf. The only break worth a mention is Jetty, and even then, the verdict is mostly "poor surf conditions" right through the whole period. There are no standouts, no hidden gems, just a lot of wind and lumpy water. For an area known for its consistency, a long quiet spell like this is unusual, so don’t lose hope—forecasts can turn around.

The first sniff of anything slightly more promising doesn't arrive until Thursday, 16th July. That morning we see a small hope with surfable but very ordinary waves. Swell is a weak 2.3ft from the south, with a period of 7 seconds (combined energy of all swells directed here is 65). The real bright spot? The wind goes WNW at 6 mph, giving us a clean, cross-offshore breeze. It’s small, but it'll be clean.

Then, on Friday, 17th July morning, we get a tiny moment of magic. The wind drops to nothing—a glassy NNE breeze at just 3 mph. Swell is still small, 2.0ft from the south with a 7-second period (combined energy 70). The water temperature here is a very unusual 73.9°, which is 4.7° warmer than normal for this time of year—that’s a real anomaly, stays in the water a bit longer. For a brief window, conditions will be glassy and clean. But the surf itself is tiny, so only a longboard or a foamie will get you going.

After that, it’s back to drudgery. The rest of the second week looks poor—cross-onshore winds, choppy wave faces, and dropping swell sizes. There is nothing here for the kites either—the wind is either too light or onshore, so it’s a washout for everyone. Save your energy. This stretch is a write-off.

Stay patient, stay salty.

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.
