The Lowdown
Alright, crew, Rusty here. Let's be real with you: the next couple of weeks are looking like a flat spell for a proper surf. We've got a long stretch of small, junky waves and messy winds ahead. It’s not a total write-off, but you're going to have to pick your moments and lower your expectations.
We’re looking at Flies (beach/jetty) for this whole run. It's fairly consistent, but that doesn't mean much when the surf quality is this poor. The swell energy is all over the show, mostly weak with some moderate pulses, but the period is short and the direction is all wrong. For the vast majority of this time, there’s just nothing doing.
The first few days, from Wednesday the 5th right through the weekend, are a total bust. We're talking tiny, wind-blown slop with cross-shore winds chopping everything up. The combined energy is mostly in the weak range, between 57 and 80, with a brief jump to a moderate 149 on Saturday morning, but that comes with a strong cross-off wind and a junky 3ft swell at 6 seconds. It’s not worth your time.
There is a tiny glimmer on Friday morning, the 7th. The swell drops to 3ft and the wind swings to a light cross-off, leaving the surface clean. The energy is weak at 67, and it's still a short-period swell, so it's not going to be epic. But if you're desperate for a grovel, that's your best bet in this first week. Sunday morning the 9th is similar, a little more energy at 84, still small and clean.
The middle of the week from Monday the 10th through Thursday the 13th gets worse. The wind picks up, especially Monday afternoon with a fresh 19 mph cross-shore making it lumpy, and there's even a risk of thunderstorms. The swell stays small and weak, with energy readings dropping as low as 21. Just save your energy.
Now, there are a couple of standouts in this otherwise bleak forecast, but you gotta look ahead. The first is on Wednesday morning, August the 12th. The wind goes offshore from the NNW, the sky is clear, and the ocean is clean. It's only 2ft at 6 seconds, so it's small, but that offshore wind will make the most of it. The energy is weak at 34, so it's not powerful, but it will be the cleanest surf we've seen. If you're a longboarder or riding a log, this could be a fun little session.
The other real highlight is much further out, on Tuesday morning, August the 18th. The wind goes glassy – completely dead – and we get 2ft of swell at 8 seconds. The combined energy is a moderate 64. It's not big, but glassy conditions with a slightly better period is a genuine rarity in this forecast. That will be a clean, if small, morning on the inside.
Beyond that, the second week is mostly small, weak, and messy. The 16th and 17th look particularly poor with tiny waves and mixed winds. The 19th and 20th just fade out with more cross-shore junk. The water temp is about average for the time of year, so no surprises there.
So, the call is this: don't hold your breath for the next few days. If you're keen, check the Friday the 7th morning or Sunday the 9th. But the real highlights are Wednesday the 12th with offshore wind, and the glassy morning of Tuesday the 18th. Both are small, but they're clean, and sometimes that's all you can ask for. The long-range stuff on the 18th is promising, but remember, it's a long way out and things can change.
Stay patient.
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.
