The Lowdown
Alright, Rusty here, checking in on the only spot that’s got any kind of pulse in the forecast. Let’s be real, it’s looking like a quiet stretch, but we’ve got a few windows to work with at Jetty.
First up, the water temps are sitting right around 71°, which is just a tick cooler than average for this time of year. No big deal, just a slightly nippy start to the session.
The overall pattern is pretty weak. We’re looking at a long, slow grind with very little energy. From Sunday the 26th right through to the end of July, the waves are small and the wind is mostly junk. Sunday morning (July 26th) gives us a tiny 3 ft swell from the ESE at a short 7 seconds. The combined energy is a measly 77, so it’s weak. The wind is a cross-offshore from the NE, so it’s clean, but the waves are just too small and weak to get excited about. The afternoon turns to onshore, and it’s a write-off.
Monday and Tuesday are a total loss with onshore winds and poor conditions. Wednesday the 29th sees a bit more size, with the swell pushing 5 ft from the SE, but the wind is a strong cross-onshore from the East at 30 km/h, making it lumpy. The energy jumps to 170, but it’s not surfable. This setup is honestly looking more interesting for kite surfing than paddle surfing.
We start to see a glimmer on Thursday the 30th. The wind swings around to a cross-offshore from the NNE, cleaning things up. The swell is 4 ft from the East, but the period is still short at 6 seconds. The energy is moderate at 214, but the waves are just messy. The highlight of the whole forecast, and I mean the only real standout, is Friday afternoon, July 31st. The wind goes glassy, dead calm from the WNW at 5 km/h. The swell drops to 3 ft from the SSE with an 8-second period, and the energy is moderate at 130. It’s small, glassy, and clean. For a beach break, this is your best bet. The crowd profile says “sometimes” packed, so you might have some company, but for waves this small, it won’t be crazy.
Saturday morning, August 1st, is also glassy but the swell is even smaller at 2 ft from the S. It’s a similar story, surfable but very ordinary.
After that, it’s a desert. From Saturday afternoon all the way through to the end of the forecast on August 10th, it’s a long stretch of tiny, wind-affected junk. The swell drops to 1 ft, the wind is mostly onshore or cross-onshore, and the energy is in the 30s and 40s. There’s one clean, offshore morning on August 7th, but it’s on a 1 ft swell. Not worth paddling out for.
So, bottom line: if you’re desperate, aim for a glassy session on Friday afternoon, July 31st, or Saturday morning, August 1st. It’s not going to be epic, but it’s the best we’ve got. For the rest of the run, leave the boards at home.
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.
