The Lowdown

Alright folks, Rusty here. Let's have a look at what Road K has on offer for the next couple of weeks. The short version? It’s a quiet stretch, with only fleeting moments that look any good. We’ve got a run of dodgy conditions for most of the first week, and while things might tidy up towards the second week, the swell is tiny.

The first proper chance of a paddle is Wednesday morning, August 26th. The wind is a light offshore from the NW at 9 mph, which is a major positive – it’ll keep things clean. With a small 2 ft SE swell at 9 seconds, it’s not going to be big, but it’s rideable. The combined wave energy is weak (48), so you'll be hunting for the little runners.

Then we hit a dry spell. From Wednesday afternoon right through to Monday, August 31st, it’s a write-off. The wind swings onshore or cross-shore, the sea gets choppy and lumpy, and the scores are flat. There’s a small window on Monday afternoon when the wind drops out, with clean 2 ft waves, but the period is a short, weak 4 seconds (energy 45) – not really worth getting excited about.

Heading into September, the first few days stay poor. A little bit of glass on Wednesday afternoon, September 2nd, with 2 ft SE swell at 11 seconds and moderate energy (125), could be a sneaky session for the patient surfer. The wind is calm, making for a nice clean surface, but the swell is still marginal.

The best bet across the whole forecast is Saturday morning, September 5th. The wind is a light offshore from the NE at 6 mph, giving us clean conditions. The swell bumps up slightly to 2 ft from the E at 8 seconds, and while the energy is moderate (101), it’s the best combination of clean conditions and a little bit of energy we see. For a sandy beach break, it’s not going to be amazing, but it’s the standout of the 16 days. For beginners, the 2 ft to 3 ft range is fine, so don’t be scared off.

After that, the swell fades back to tiny, messy waves for the rest of the second week. The 8th and 9th of September are particularly weak, with energy readings in the 20s and 40s – not worth the look. For a spot that’s very consistent, this is a frustrating run. It won’t stay this flat forever, but right now, the outlook is pretty bleak. Road K is an exposed sandbar, and with the swell this small and the wind turning bad so often, this setup actually looks more interesting for kite surfing than paddle surfing during the crummy afternoon sea breezes. The water temp is about average for the time of year.

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.
