Table - best surf conditions forecast for Road K over the next 16 days.
Alright mates, Rusty here. Let's break down what the next couple of weeks are looking like for the local surf.
The short story is it's a bit of a slow burner. We've got a lot of wind and poor conditions in the early going, but there's a decent pulse of swell coming in the second week if you've got the patience.
Road K is the only break on the map, a sandbar setup that's always breaking. It's a good spot for beginners, but it's going to feel a bit of a grind. The water temp is sitting about 69°, which is pretty normal for this time of year.
The first week is a struggle. From Saturday the 11th through to Tuesday the 15th, the swell is tiny, under 3 feet, and the wind is all over the place – cross and onshore. The wave energy is weak, between 27 and 104, with short periods of 5-7 seconds. It's just choppy and messy. The only bright spot is Wednesday morning the 15th, with a 4ft SW swell and a light cross-offshore wind keeping things clean. The energy jumps to 174 (moderate), but it's still pretty ordinary.
Thursday the 16th and Friday the 17th offer a couple of small windows. Thursday morning the 16th has a 2ft SSW swell with a 6-second period and a light offshore wind from the NW. It's clean, but small and weak (energy of 41). Friday morning the 17th is similar with a 3ft SSW swell and clean conditions. Those are the only two sessions in the first week that are even worth a look, but they're not standouts.
Then there's a real gap. From Saturday the 18th through to Tuesday the 22nd, the surf is pretty much a write-off again. Tiny swell, poor winds, lumpy. Not worth the effort.
Now, the highlight. The real action starts to build around Wednesday the 23rd of July. The swell pushes up to 5-6 feet from the east, with a 6-7 second period. The wave energy hits 238 and 266 (moderate). The problem is a cross-shore wind, making it lumpy and cross-chop. It's not clean, but there's definitely more water moving.
The standout session, and the one you should mark on the calendar, is Saturday the 25th and Sunday the 26th of July. The swell is a solid 5-6 feet from the SSE with a period of 9-10 seconds. The wave energy is pumping, hitting 471 and 508 (strong to very strong). This is a real groundswell. It can be a bit tricky at a sandbar with that long period, but it will have power. The wind is the key. Saturday the 25th is a mess with a strong cross-shore, but Sunday morning the 26th is the one. The wind swings to a cross-offshore from the NNE, keeping things clean. For anyone with some experience, that Sunday morning session is the best bet of the entire 16-day window. This size is for the experienced crew, not beginners.
So the bottom line: the first week and a half are a tough slog. The best of the early stuff is the small, clean windows on the 16th and 17th, but the real prize is the solid, powerful swell on the weekend of the 25th and 26th, especially Sunday morning the 26th if the wind plays nice.
Rusty.

Information about the Road K Surf forecast
The above surf forecast table for Road K provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Road K can be found by selecting the local surf guide option on the grey menu. Our Road K 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 (Road K) 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 Road K 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.
Road K is 28 km (17 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.
