The Lowdown
Alright folks, Rusty here. We’ve got a bit of a quiet stretch ahead at the Jetty. Let’s break it down.
Look, I’m gonna be straight with you – the next week and a half is pretty much a write-off. The Jetty (Jetty-4) is a breakwater setup that’s exposed to the swell, but we’re just not getting the goods. We’ve got a long gap with no real surf on offer. The first few days are all “poor surf conditions” with scores of zero. The water is sitting at 71°, which is a touch warmer than normal for this time of year, but that’s about the only thing going for it.
Thursday the 10th sees a bump in swell to 5ft from the SSW, and the combined energy kicks up to 373 (moderate wave energy), but the wind is cross-shore from the WSW at 12-16 mph, making it lumpy and messy. Not worth paddling out for.
Friday the 11th morning is the only real tease. The wind goes offshore from the North at 9 mph, giving us clean conditions. But the swell is tiny, only 2ft from the South with a short, weak period of 6 seconds and energy of 33 (weak). It’s clean, but there’s nothing to ride.
We then drift through a whole week of tiny, onshore, or cross-shore junk. Spots of glassy or clean conditions on the 14th and 16th, but the swell is miniscule – 1ft to 2ft. This is a real desert period.
Saturday the 19th afternoon finally shows a glimmer. The swell picks up to 4ft from the ENE with a combined energy of 219 (moderate wave energy). It’s onshore wind from the SSE though, so it’s not going to be great. The report says “marginal surf forecast,” so it’s a watch-and-see situation.
The best bet on offer, and I’m using that term loosely, is Saturday the 19th afternoon. The Jetty might see some 4ft ENE swell, but the onshore wind will keep it rough. It’s the only time in the entire 16-day window that even gets a score of 1 out of 10. It’s not good, but it’s the only thing we’ve got. Crowds are possible at the Jetty, so don’t expect to have it to yourself, but there won’t be many out.
For the rest of the run into the 24th, it’s a mix of small SE slop and cross-shore winds. The wind stays up around 12-19 mph through the 24th, with energy finally climbing back up to 256 (moderate wave energy) on the 24th afternoon, but it’s all cross-shore and lumpy. Nothing to write home about.
Stay patient, and keep an eye on the 19th, but don’t get your hopes up.
Rusty.

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.
