The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are a bit of a mixed bag, and you’re going to need some patience. We’re looking at a stretch where the consistency is there, but the quality is going to be a real test of your dedication. It’s not all doom and gloom though, there is a window of proper surf hiding in there if you can wait it out.
The first week or so is pretty grim for good waves. We've got a run of days where the wind is all over the shop, mostly cross-shore or cross-on, kicking up a chop that’ll have you fighting the board more than riding it. The swell is small, around the 3ft mark, and pretty weak, with the combined energy only reaching the double digits – think 59 to 93 – which is nothing to get excited about. It’s the kind of surf that’ll have you checking your watch more than the horizon. We call this the “why did I even bring my board” period.
Now, there is a tiny blip on Monday the 10th. For the morning session, the wind drops right out to give us a glassy surface. The swell is still tiny at 2ft with weak energy (41), but at least it'll look pretty and be clean. If you’re a pure log enthusiast or a beginner just wanting to get wet, that might be your window. The afternoon, though, the wind swings onshore and chops it all up again. It’s a tease, really.
The following days just continue the trend. More small swell, poor conditions. We see another slightly cleaner window on Wednesday morning the 12th with a light cross-offshore breeze making it clean, but the swell is still only 2ft with weak energy (44). It's another so-so one for the longboard crew.
After that, the surf just kind of fades away. We’re looking at a real lull from the 13th through to the 17th where the swell drops to 1ft. The energy is just pitiful, down in the 18 to 49 range. It’s flat-ish, and for a beach and sandbar set-up like Road K, that means it's probably not breaking at all. It’s a real test of patience, but this blank run is pretty normal for this area when we get this pattern.
You’ve got to wait for the second week for the good stuff. The real standout starts to show up on Tuesday the 18th. The morning is a hint, with a clean but small wave, but the real push comes in the afternoon. The wind swings offshore and it’s a fresh breeze, and the swell jumps up to a more respectable 5ft with the combined energy jumping to a moderate 148. The period is short at 5 seconds from the SSW, so it’ll be a bit crumbly but it's the first real sign of life.
But the main event, the one you’ve been waiting for, is Wednesday the 19th. This is the standout of the whole period. The wind is offshore for the whole day. In the morning it’s a moderate offshore breeze with a solid 6ft swell from the S, and the energy is strong, hitting 329. The period is still on the short side at 8 seconds, but the power is there. The afternoon looks even better, with a light offshore breeze keeping things clean, and a 5ft swell with energy still pumping at 259. This is the day to pull the trigger. The swell direction from the S is right in the wheelhouse for the optimum direction, and with that offshore wind, the sandbar at Road K could set up some fun, punchy wedges. This is for the intermediate crew, as it's over 5ft, so it might be a bit much for beginners.
After that, the swell drops back down for the last couple of days of the window. The wind is back onshore on the 21st and the energy drops back to a moderate 104, with a small 2ft swell. It’s a fade-out, so get your fill on the 19th.
Bottom line: if you’re keen, circle the 19th. It’s the clear winner. The rest is a waiting game, but that’s how it goes sometimes. Get out there when it’s clean and small if you can, but save your energy for Wednesday the 19th.
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.
