The Lowdown
Alright crew, Rusty here. Let’s be straight with you: this Road K stretch is lookin’ like a long, quiet spell for paddle surfing. For the next week and a half, there’s just not enough energy or clean wind to get excited about. We’ve got a solid 16-day window ahead, but honestly, the first ten or eleven days are a bit of a dud for a proper surf.
For Road K we’re looking at weak, short-period wind swell most of the time – think 2 ft to 4 ft from the south or south-southwest, with periods hanging around 6 to 7 seconds. That’s not delivering any punch. The combined energy is flirting with moderate values (230) only on Sunday the 9th morning, but even then, the wind is cross-shore and the conditions are only marginal at best. Most other days the energy is weak (59 to 126), and the wind is either onshore, cross-onshore, or just messy. Thursday morning the 13th and Wednesday the 12th morning offer a brief moment of clean conditions with light offshore or light wind, but the swell is tiny (2 ft to 3 ft) and weak – really just a dribble.
If you're a beginner, the tiny stuff (under 5 ft) is fine size-wise, but the short period and cross-chop will make it frustrating. For everyone else, it’s a lot of groveling at best.
Now, let’s talk about a couple of standouts. The best chance we see is on Sunday the 9th morning. We get the biggest bump of the first week: 4 ft from the south-southwest (7 sec), with combined energy climbing to 230, which is moderate. The wind is light and cross-shore from the west-southwest. It’s still only a 1 out of 10 in quality, so don’t expect magic, but it’s the only time in the first week where the energy is decent enough to hold a bit of shape. Crowds are often around here, so expect company.
If you can wait, the tail end of the forecast from the 19th and 20th looks like a different story – but it's far out, so treat it as promising but less certain. Wednesday the 19th afternoon and Thursday the 20th morning bring the biggest swell of the whole window: 5 ft to 6 ft from the south-southwest, with combined energy climbing into the strong range (199 to 269). The period stays short (6-7 seconds), which means it'll be lumpy and not super well organised, but the size will be there. The wind will be cross-onshore and fresh, so it's gonna be a bit of a battle. For strong, experienced surfers only at that size – 6 ft is pushing the limit for a beach break.
The water temp is sitting around 73°F with a tiny anomaly of +0.5°F, so it’s about average for early August. No need for a thick suit.
Hang in there. Week two looks a bit more promising for size, but the wind is still a challenge. Keep an eye on it.
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.
