The Lowdown
Alright folks, Rusty here. Gotta be straight with you straight away – this 16-day window for Flies is a real mixed bag. We're looking at a long, quiet start with a few days of nothing much, then a bit of a tease in the second week, and a possible late burst of energy that could be the one to watch. Let's get into it.
The first week is pretty grim. From Saturday the 8th right through to the start of the following week, it's mostly small, weak, and poorly aligned. The combined energy is low, barely cracking triple digits most days, and the wind is all over the shop. Saturday morning's got a few 3 ft waves from the SSW, but a moderate 12 mph cross-offshore breeze is making a mess of it. Sunday afternoon is a bit better with 4 ft waves, but the energy is still weak (230) and the conditions are just marginal. Monday the 10th is the only real highlight of this first stretch: a glassy morning with a light 3 mph wind from the WSW and clean 2 ft surf. The swell's tiny though, with a combined energy of just 36, so it's a micro-wave session. The water temp is about average for this time of year.
The mid-week period, from the 13th to the 15th, is a write-off. We're talking knee-high slop at best, with combined energy dropping into the teens and twenties. It's a proper flat spell.
Then, things get interesting from the 22nd of August. Saturday the 22nd morning is looking like the standout of the whole forecast. The waves are a clean 3 ft from the SE, with a nice long 12-second period and a combined energy of 248 (moderate). The wind is glassy from the north, a mere 3 mph. This is the kind of morning you set an alarm for. The long period is a bit of a caveat for a beach setup like this, as it can make the waves break a bit straight, but with no wind it's worth a look. The afternoon goes to crap with a 12 mph southerly, so get in early.
The very end of the window, Sunday the 23rd of August, has a bit of a different look. The swell jumps up to 8 ft from the S, with a short 6-second period, and a combined energy of 446 (strong). The wind is a light 9 mph cross-off from the WSW, which should keep it clean. The size is getting into the "too big for beginners" territory, and the short period will make it a bit lumpy and roly-poly. It's a bit of a wildcard, but for the more experienced crew, it could be a fun, punchy session.
So, to sum it up: the first week and a half are lean. The one true standout is the morning of Saturday the 22nd of August – clean, glassy, and with a nice long-period SE swell. That's your best bet. The Sunday the 23rd is a bigger, messier option for the brave.
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.
