The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The next 16 days are looking like a real mixed bag for Flies, with a long stretch of flat, ugly conditions before we finally see a proper pulse of energy. The first real surf we can talk about isn't until Thursday, July 23rd, and it's a bit of a sad start.
The overall pattern is one of very small, short-period swell and funky winds, meaning we’re in for a lot of waiting around. There’s a big gap of pretty much nothing from the afternoon of the 23rd all the way through to the end of July. Days and days of poor surf, with tiny waves and onshore slop. It’s a real bummer.
Now, let’s get specific. The first bit of action is on Thursday morning, July 23rd. Flies is seeing a very ordinary 4ft swell from the south, with a short period of 8 seconds. The wind is a light N at 9 mph, but it’s blowing cross-offshore, which is about the only good thing here. The combined wave energy is weak, just 182. The water is 69°, which is a bit colder than normal for this time of year, so you’ll want a thicker suit. The conditions are clean, but the waves are just surfable, not exciting. For a beach/jetty setup, it’s a tough call to get excited about.
The real standout, the only one worth marking on the calendar for a proper session, is Monday, August 3rd. Now, that’s over a week away, so keep that in mind – it’s a promising long-range call, but not locked in. On the morning of August 3rd, we get a clean 5ft swell from the south with light offshore winds from the WNW at 6 mph. That’s a solid setup. The combined energy is moderate (202). But the absolute gem is the afternoon of August 3rd. The swell jumps to 8ft from the south, with a period of 10 seconds, and the wind switches to a light cross-offshore from the SW at 6 mph. The combined energy here is a massive 1106 (very strong energy). This is serious, powerful surf. The waves will be excellent for experienced surfers. This is too big for beginners, and at that size, the short period (10 seconds) at a beach/jetty might mean it’s a bit lumpy, but for the crew that can handle it, this is the session to chase.
After that, it falls off again. Tuesday, August 4th, sees a 5ft swell but with cross-shore winds, and it’s only marginal. The rest of the second week fades back into small, onshore, and choppy conditions.
So, to wrap it up: don’t bother with the rest of July. The run of poor surf is long, but that’s just how it goes sometimes. Save your energy for the afternoon of Monday, August 3rd. That’s the one. It’s a long way out, but it looks like a proper hit.
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.
