The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer at Flies over the next couple of weeks.
Honestly, mate, it’s a pretty tough stretch. We’ve got a real long dry spell kicking off here. For the first week and a half, the swell is tiny and the conditions are just ordinary. You’re looking at a whole lot of days with poor surf and next to no energy. There’s a big gap of surf that just isn’t worth chasing until we get towards the middle of the second week.
The first real standout that might get your heart beating a little is on Monday morning, the 17th of August. Now, this is a bit of a wildcard. The swell bumps up to 7ft from the SSW, and the combined energy jumps to 374 – that’s moderate wave energy. But here’s the catch: it’s howling onshore with a light rain and a 12 mph wind from the S. That’s gonna be a mess. This is a beach/jetty setup, so with that much wind and swell, honestly, this is looking more interesting for the kite surfers than a paddler. It’s not beginner-friendly at over 5ft, and it’s only really for the experts if you’re brave enough to deal with the chop.
The next decent window comes on Tuesday morning, the 18th of August. The swell drops back to 3ft from the S, still with that 7-second period, but the energy is 135 (moderate). The wind swings around to a light N at 9 mph, giving us a cross-off breeze. It’ll be clean. It’s just a very ordinary, small wave day. Not a standout, just the most surfable of a bad lot.
Then on Friday morning, the 21st of August, there’s a little flash. The swell is 3ft from the SSE, period 6 seconds, energy 115. The wind is a whisper from the WNW at 3 mph, making it glassy and clean. The waves are surfable, but the conditions are still just ordinary. It’s a very small window.
The best of the bunch, the one true standout, actually looks like Saturday morning, the 22nd of August. The swell is a tiny 2ft from the SE, period 8 seconds, energy 101. It’s weak, but the wind is light from the SW at 6 mph, giving a light cross-shore. It’s not going to be pumping, but for a longboard or a funboard, it’ll be the cleanest, most user-friendly wave of the whole period. The water temp is about 74°F, which is about 2°F warmer than normal for this time of year – a nice little bonus if you’re paddling out.
Beyond that, the last few days of the forecast are a write-off with a risk of thunderstorms and strong winds. Not worth a second look.
So, to sum it up: the first week is a total bust. The only real chance to get a clean, small wave is on Saturday the 22nd. If you’re desperate, Monday the 17th has size but it’ll be a battle against the wind. Keep your expectations low, and the forecast might change, but for now, it’s a long wait.
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.
