The Lowdown
G’day, Rusty here. Let’s get real about the next two weeks. It’s mostly small and messy, with a few clean windows if you’re patient. The good news is the water is sitting at 74°, which is about 1° warmer than average for this time of year. Not a big deal, but it’s a touch warmer than usual.
The pick of the early days is Sunday morning, the 10th of August. We’ve got a tiny 2ft southwest swell, but the wind is glassy offshore from the southeast. It’s weak energy (26), but it’ll be the cleanest surf of the early run. Flies (Mar del Plata) is the spot, a beach/jetty setup that’s fairly consistent and exposed. It won’t be big, but it’ll be clean.
A couple of days later, on the 14th, a light northwest offshore breeze should keep things tidy with a 2ft south swell. Again, small, but clean. The next morning, the 15th, is similar – a northwest cross-off breeze and a 2ft south swell.
Now, the one standout is Friday morning, the 22nd of August. This is where the energy picks up. We’ve got a 3ft southeast swell with a 12-second period, giving it some real push. The combined energy is 243, which is a solid boost from the weak stuff. The wind will be light cross-on from the south-southwest, but the long period should shape things up nicely. It’s a week and a half out, so it’s promising, but keep the expectations in check until it’s closer.
There’s also a pulse on the 21st with a 4ft southeast swell and 358 energy, but the cross-onshore wind will likely chop it up.
The rest of the two weeks is mostly small and bumpy. There’s a poor patch from the 18th to the 20th, and then it gets windy again on the 23rd.
So, here’s the plan: the mornings of the 10th, 14th, and 15th are your clean, small-wave sessions. The big fish is the 22nd, but that’s a long way out. Don’t over-commit, keep an eye on the wind, and I’ll see you in the water.

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.
