The Lowdown
Alright, Rusty here. Let’s have a look at the next 16 days.
Well, I’m not gonna lie to you, it’s looking pretty grim for a while. The first spot that even shows a pulse of something rideable is Flies, a beach/jetty setup, and it doesn’t really get going until the very end of the month. We’ve got a solid stretch of nothing from the start of August right through to the 8th, with only tiny, weak, and messy waves on offer.
The first real glimpse of anything half-decent is on Thursday, July 30th, but even then it’s a letdown. We’ve got about 3 ft of SSE swell, but it’s short-period at 8 seconds, and the wind is a cross-off from the NNE. The combined energy is weak (170), and the water is warm at 71 °F, which is about average for the time of year. The report says “poor surf conditions,” so I’d give it a miss.
Friday, July 31st, morning is your best chance in the near term. The swell drops to 3 ft from the SSE, period bumps up to 9 seconds, and the wind goes totally glassy – dead calm, 0 km/h. That clean, glassy surface will make the most of what’s there. The combined energy is still modest (127), but for a quick session, it’s the only real standout. Even then, it’s just “surfable waves but very ordinary conditions.” The crowds are a possibility at Flies, but with surf this small, it might not be too bad.
After that, it’s a long, long wait. From Friday afternoon, July 31st all the way through to Saturday, August 8th, it’s a mess of onshore winds, cross-chop, and tiny, weak swells. The wind is mostly from the S or SSW, blowing cross-on, and the wave heights hover around 1 ft to 4 ft, but with periods as low as 4-7 seconds. The energy numbers are all triple-digit at best, but the quality is just awful. A few days have a risk of thunderstorms too, which isn’t going to help.
There’s a tiny flicker of hope on Sunday, August 9th, morning, with a clean cross-off breeze from the NNW and 3 ft of SSW swell, but the period is a snappy 5 seconds, so it’s not going to have any push. The energy is weak (52). It’s “surfable waves but very ordinary conditions” again.
Monday, August 10th, morning is similar – 3 ft from the SSW, 6-second period, clean with a light NNW breeze, and combined energy of 82. It’s an option, but it’s not going to set the world on fire.
Tuesday, August 11th onwards sees the swell drop right off, with heights under 2 ft for the rest of the run. A few clean mornings with light offshore winds (like Thursday, August 13th, morning with a 1.0 ft SE swell and a NNW breeze), but you’d be scratching for anything.
So, to be blunt, the best on offer is Friday morning, July 31st at Flies. It’s not a classic, but with glassy conditions and a little bump of SSE swell, it’s the only time you’ll get a clean wave. Everything else is a write-off or a long shot. For a beach/jetty break, this stretch of poor surf is pretty normal for the area, so don’t hold your breath.
Rusty.

Information about the Flies Surf forecast
The above surf forecast table for Flies provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Flies can be found by selecting the local surf guide option on the grey menu. Our Flies 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 (Flies) 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 Flies 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.
Flies is 32 km (20 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.
