Rusty here again, and I gotta tell you, it's a rough go for Road K. This 16-day window is a total bust – not a single session worth your time.
We kick off Saturday, July 4th, with ankle-snappers at 0.4m from the southeast. Combined wave energy is a paltry 52. It's clean in the morning with a cross-offshore breeze, but by afternoon the wind turns onshore and it's game over. Sunday's the same story – a 0.6m windswell with a 5-second period, blown straight out.
Monday the 6th brings some height – 6ft to 7ft of east swell – but it's all short-period junk. The wind is howling at 28 mph onshore, making it a total washing machine (combined energy of all swells directed here: 246 to 348). This setup looks more interesting for kite surfing than paddle surfing.
Tuesday the 7th is a tease. We get 5ft to 6ft of east swell with a strong 28 mph cross-offshore wind that'll keep the surface clean. But the period is a weak 7 seconds. The combined energy is decent at 291, but the waves will be closed-out and weak.
Wednesday the 8th is the closest we get to a maybe. Morning has 5ft from the ENE, period of 7 seconds, with a cross-offshore breeze. The combined energy jumps to 377, but the forecast says it's marginal.
From Thursday the 9th through to the 19th of July, it's a brutal stretch. Tiny waves, onshore winds, and low energy dominate. We get a glassy morning on July 15th with a tiny 2ft of short-period slop, but that's it. This is a solid 10-day run of no surf. For a place like this, a complete blank is normal, but it doesn't usually stay poor this long.
No standouts. None at all. Just a waiting game now. Keep that board waxed for another day.
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.
