The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for the next couple of weeks.
First thing you gotta know – we’re in for a long, quiet stretch. The first real chance of a wave doesn’t show up until Wednesday morning, the 29th of July. Before that, Monday and Tuesday the 27th and 28th are a total write-off. The wind is howling cross-on and the swell is either weak, short period, or just plain messy. Energy is low (38) on Monday afternoon, and Tuesday’s only hitting 115 but it’s a windswell with a 5-second period, so it’s junk. Leave the board in the car.
So, the run starts on Wednesday morning, July 29th. The break to look at is Flies. It’s a beach and jetty set-up, fairly consistent. The water is running a bit colder than normal for this time of year, about 70°, so it’s a couple of degrees off the average—worth a light steamer if you feel the chill.
Wednesday morning is clean as a whistle. We’ve got a gentle cross-off breeze from the WSW, and the swell is coming in at 5 ft from the SE with a period of 7 seconds. The combined energy is moderate at 282. It’s not epic, but it’s clean and surfable. The swell direction is coming from the SE, which is the optimum direction for this spot. That’s your best bet for the week.
Thursday morning, July 30th, is also a contender. The wind goes offshore from the WNW, light breeze. The swell drops a little to 4 ft from the SSE, but the period stretches to 9 seconds, giving it better shape. Energy is still moderate at 258. It’s going to be clean, but the sets might be a little more spaced out. Thursday afternoon is glassy, dead calm wind from the west at just 5 km/h, but the swell drops to 4 ft. It’s rideable, but very ordinary.
Friday morning, the 31st, the wind is cross-off but the swell is back down to 3 ft. The energy is waning (161). It’s clean, but small. Not a standout.
After that, the forecast takes a nosedive. From Saturday, August 1st, all the way through to the 11th of August, it’s a long stretch of poor conditions. The wind is either onshore, cross-on, or just side-shore, and the swell is tiny, often under 3 ft, with weak energy readings dropping into the double digits. There’s a brief moment on Thursday morning, August 6th, where the swell picks up to 3 ft from the S with a cross-off breeze, but it’s a short period windswell at 5 seconds, and the energy is only 56. It’s clean, but not worth chasing.
To be honest, the one real standout in this whole 16-day window is Wednesday morning, July 29th at Flies. The combination of a clean cross-off breeze, a 5 ft swell from the optimum direction, and moderate energy makes it the pick of the bunch. Thursday morning is a close second, but the swell is a touch smaller. Other than that, get ready for a lot of flat, blown-out days. The forecast might change, but right now, it’s looking like a long dry spell.
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.
