Alright, this is Rusty. Let's have a look at what's on offer at Flies.

Right now, things are pretty flat and messy. We’ve got a long, quiet spell ahead. For the next week and a half, it’s all tiny, weak, and poorly directed. The water’s sitting at a touch warmer than normal for the time of year at about 72.1°, which is a bit of a novelty, but not much else to get excited about. We’re looking at a real drought here until we get a pulse of proper swell.

The first real glimmer of hope arrives way out on Saturday the 18th of July. Overnight, a solid 6.2ft swell from the S rolls in, with a combined wave energy reading of 520 – that’s proper moderate energy – and it looks clean under light westerly winds. That Saturday morning window is the standout. It’s a significant size, so it will be pushing into intermediate territory and above. The swell is short period though at 8 seconds, so it’ll be a bit of a windswell feel. Sunday the 19th keeps the party going with a slightly smaller but still solid 5.6ft swell from the S, period stretching out to 9 seconds for a bit more shape. That Sunday morning brings clean offshore NW winds at about 6 mph, which is a real treat and should groom the waves nicely. The energy readings stay strong, around 508, so it’s got some punch.

Don't get too excited about the afternoons on those days. The Saturday afternoon picks up a cross-onshore wind, making it choppy and less appealing. The Sunday arvo gets cross-shore wind, which will chop things up.

For the best of the lot, I’d be targeting the Saturday the 18th morning session. That 6.2ft S swell under light westerly winds is the pick of the whole 16-day run. It’s not perfect, but it’s the most size and clearest we see. Keep in mind, this is a beach/jetty setup, so with that 8-second period it might be a bit dumpy, but it will still be rideable. Sunday morning is the solid runner-up with the offshore wind.

After that, we fade into smaller, weaker surf again with onshores and chop through the middle of the second week, before a tiny glassy window on Tuesday the 21st morning – but at 2.3ft and weak energy, it’s just a gentle paddle.

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.
