Alright, Rusty here. Let’s take a look at what’s on the menu for the next couple of weeks at Road K.
Right off the bat, I’ve gotta be straight with you – this ain’t a pretty picture. We’re looking at a long, dry spell with barely anything worth paddling out for. The first few days are a write-off. Thursday the 9th and Friday the 10th? Forget it. The swell is tiny, the wind is all over the shop, and it’s just not doing anything for us. The combined energy is barely a whisper, just 73 (moderate cross-shore chop) on Thursday, dropping to a 55 on Friday. It’s anemic.
We do get a tiny window of something that looks a bit more promising on Saturday the 11th morning. A 2ft swell from the S at 7 seconds, with a light NE cross-offshore breeze. The combined energy is a weak 65, but it’s clean. The water’s a touch warmer than normal for this time of year, so that’s a small win. But don’t get excited – the waves are small and the period is short, so it’s a longboard or a foiler kind of day. It’s surfable, but ordinary.
After that, it’s back to the doldrums. Sunday and Monday are a mess of onshore winds and small, choppy surf. The wind stays on it for days, and the swell is just not there. The best we can hope for is a brief moment of glassy calm on the morning of Monday the 20th, but with only 1ft of swell from the E at 6 seconds and a combined energy of just 24, it’s flat. You’re better off taking a walk.
Now, here’s where it gets a little interesting. On Tuesday the 21st, the swell jumps up, but don’t be fooled. The wind is a crummy cross-onshore from the SSW, and the combined energy is a massive 301 by the morning. By the afternoon, it’s a thumping 10ft from the SSE with a combined energy of 1033! That’s some serious juice. But the period is a short, bumpy 8 seconds, and the wind is chopping it all up. In a beach-and-sandbar setup like Road K, this is going to be a messy, closed-out wall of whitewater. Honestly, that’s more of a kite-surfing session than a paddle-surfing one. It’s for experts only, and even then, it’s not going to be pretty.
The rest of the third week follows the same pattern: plenty of swell energy but ruined by onshore winds. The swell on the 22nd is still big, with a combined energy of 557, but it’s the same story – onshore, choppy, and messy. Don’t even bother.
So, the best on offer? I’d have to say the early morning of Saturday the 11th is your only real shot at anything clean, and even then, it’s small. The big pulse around the 21st is a miss. There’s no standout. We’re in a bit of a blank run, and for this area, that’s not unusual. It’ll turn around eventually. Keep watching the charts.
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.
