The Lowdown
Alright, Rusty here. Let’s have a look at what’s cooking over the next couple of weeks.
Honestly, it’s a pretty grim stretch for our beaches. The only spot with any gear to talk about is Flies, a beach and jetty setup. The water temp is sitting around 71°, which is bang on average for this time of year – nothing weird going on there.
The first real chance of anything decent doesn’t pop up until Wednesday afternoon, the 15th of July. We’ve got a 4ft swell rolling in from the southwest, with a short period of 6 seconds. The wind is blowing offshore from the west-northwest, which will keep the surface clean, but the wave energy is weak (189). It’s surfable, but it’s ordinary.
Thursday, the 16th, through the weekend is a write-off. The swell drops off, the wind goes messy, and conditions are just poor. You’ll be fighting chop and onshore crud.
The one standout is Monday morning, the 20th of July. That’s where the window opens. The swell is 4ft from the south, with a period of 9 seconds – that’s a much better, more organised groundswell. The wind is dead glassy, absolutely zero breeze. That’s rare, and it’ll make the surface perfect. The combined wave energy is moderate (278). This is the best session on offer, hands down. It’s a morning-only call though, as the afternoon gets a cross-shore breeze that chops it up.
After that Monday, it’s back to the doldrums. The wind goes onshore, the swell stays small and weak, and there’s nothing worth paddling out for. A few days in the second week show a little bump in size, like Sunday the 19th with a 6ft swell, but the wind is strong and cross-off, and the conditions are labelled poor. Not worth it.
So, to sum it up: if you’ve got a free Monday morning on the 20th, hit Flies early. Everything else in this 16-day window is a miss. We’ll see if the forecasts change, but right now, it’s a long flat 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.
