The Lowdown
Alright, let’s talk about Road K. The next 16 days look pretty flat and frustrating for most of it. We’ve got a long stretch of poor conditions on the way, so don’t get your hopes up too high.
The first real chance to paddle out comes on the morning of Friday, July 31st. It’s a small window, but it’s the best we’ll see for a while. The wind is glassy, which is a big win, and we’ve got a small 3 ft swell from the SSE. The period is a modest 9 seconds, so it’s not going to be pumping, but with those clean conditions, it’s rideable. The combined wave energy is weak (129), so it’s more of a longboard or a funboard kind of day. It’s a sandbar setup, so expect it to be a bit soft.
After that, we drop into a real rough patch. From Friday afternoon all the way through to the early part of August, the wind turns onshore and the swell gets smaller and more jumbled. The period drops to 7-8 seconds, and the energy gets weaker. It’s going to be choppy and messy. There’s a bit of a spike in energy on Monday afternoon, August 3rd, with a 4 ft swell from the S and a 7-second period, but the wind is a strong 25 mph cross-on. That’s not surfable paddling—it’s more of a kite-surfing kind of day if anything.
The next glimmer of hope doesn’t arrive until Sunday morning, August 9th. The wind finally swings offshore from the NNW, light at 6 mph, and the conditions turn clean. The swell is small, only 2 ft from the S with a 6-second period, and the energy is very weak (46). It’s surfable, but you’ll be working for it. Still, a clean, small wave beats a choppy, blown-out mess any day.
Then, on Tuesday morning, August 11th, the wind goes offshore again, this time from the N at 9 mph. The swell bumps up to 3 ft from the SSW, but the period is a short 5 seconds, so the energy is moderate (104). It’ll be a bit bumpy and weak, but the clean wind will make it look better than it is. It’s one of the few decent mornings in the whole run.
The rest of the forecast into mid-August is just more of the same: tiny swell, onshore winds, and poor conditions. The energy values drop into the teens and twenties, which is about as weak as it gets.
Overall, the standout is the first session on Friday, July 31st morning. It’s not big, but with glassy conditions and a tiny bit of swell, it’s the cleanest wave you’ll get. The Tuesday morning on August 11th is a distant second, only because of the offshore wind, but the swell is poor quality.
The water temperature is about average for this time of year, so no surprises there.
Hang in there, but don’t expect much.

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.
