The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the menu at Road K for the next couple of weeks.
Right off the bat, I gotta be straight with you—this is a tough stretch. The first real surfable session doesn’t show up until Sunday the 26th of July, and even then, it’s a pretty ordinary start. We’ve got a long, dry gap ahead with no proper standouts, so don’t get your hopes up for any fireworks.
Sunday morning, July 26th, is your best bet for a paddle. Road K is a sandbar setup, and it’s exposed to the swell. We’re looking at a 3ft swell coming from the ESE with a short period of 7 seconds. The combined swell energy is weak, only 99, so there’s not much push behind it. The wind is a light breeze from the NE, which is a cross-offshore—that’ll keep the surface clean. The water is sitting at 70°, which is a bit colder than normal for this time of year by about 2°.
Now, I’ve got to be honest: the waves are small and weak. It’s not a day to get excited about, but for a beginner or someone just wanting to get wet, it’s surfable. The good news is that the wind is light and the conditions are clean. The bad news is that this spot is often crowded, so expect some company even on a small day.
After that, it’s a real desert. The rest of July and into early August is a write-off—poor conditions, onshore winds, and choppy, lumpy messes. Late July and early August will see winds picking up strong, with some cross-on and onshore blows that trash the surface. The swell tries to build a little around Wednesday the 29th, hitting 5ft from the SE, but with a short period of 6 seconds and a fresh cross-on breeze from the E at 19 mph, it’s just a lumpy, blown-out mess. The combined energy jumps to 195 (moderate), but it’s no good for a surfboard. Honestly, this setup looks more interesting for kite surfing than paddle surfing.
We’ve got a few little respites in early August. On Saturday morning, August 1st, the wind goes glassy calm with a 3ft S swell at 8 seconds. The combined energy is 106 (moderate), but the swell is weak and the period is short. It’s a clean, small wave, but “surfable” is about the nicest thing I can say. Then on Monday morning, August 3rd, we get another glassy window with a 3ft S swell at 8 seconds and 131 energy. Again, clean but small.
The second week is a real struggle. From August 4th onward, the swell drops off and the wind stays onshore or cross-on. The few clean moments, like Friday morning August 7th with a NNW offshore wind, only have 2ft of E swell at 9 seconds. That’s tiny, weak, and barely worth paddling out for.
Bottom line: this is a lean period for Road K. If you’re desperate, the Sunday morning of July 26th is your best shot, but it’s a very ordinary session. The rest of the 16-day window is mostly a write-off, with only a few fleeting glassy moments that are too small to get excited about. Long-range prospects are uncertain, but for now, it’s not looking good.
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.
