The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Road K over the next couple of weeks.
It’s a pretty quiet start. We’ve got a big gap of nothing good from now through the end of July. The whole first week is basically a write-off – small, choppy, cross-onshore junk. You’re better off doing something else. That changes on Wednesday the 29th of July. The wind goes light offshore from the north and we get a solid jump in size. Wednesday morning we’re looking at a clean 7 ft swell from the southeast, with a period of 6 seconds. The combined energy jumps to a moderate 326, and it holds into the afternoon at 6 ft with 414 energy. The wind stays light offshore, so it’ll be clean. This is a sandbar, and with that short period it might be a bit fat, but for a mid-week score it’s the best on offer in the first week.
Thursday the 30th drops back down to a smaller 3 ft from the SSE with a cleaner 8-second period. The wind is light cross-off from the WNW, so the morning session will be clean but the energy is only moderate (162). The afternoon is similar. Friday the 31st is a bit of a tease. Morning is a clean 3 ft from the south (9-second period, 165 energy) with a light cross-off, but the real highlight is Friday afternoon. The wind goes glassy, dead calm, with a 3 ft SSE swell. It’s small, but glassy conditions are a major plus – it’ll be smooth as a lake out there.
Then we hit another dry spell. Saturday the 1st of August through to Sunday the 2nd is all small and choppy again. Nothing doing.
Now, here’s the real standout. Monday the 3rd of August. The morning brings a pumping 8 ft swell from the SSE with a 10-second period. The combined energy is a massive 1026 – that’s strong, powerful stuff. The wind is clean offshore from the NW. This is proper groundswell. At over 8 ft, this is for experienced surfers only. Beginners, stay on the beach. The period is long enough to wrap in nicely, but on a sandbar like Road K, it might be a bit straight and shifty. Still, for the crew that knows what they’re doing, this is the best wave of the whole forecast. The afternoon gets blown out by a cross-onshore SSW wind, so make it a morning mission.
Tuesday the 4th of August morning is a gem of a follow-up. Glassy conditions again with a 5 ft south swell (8 seconds, 272 energy). It’s a great size, clean, and the crowd factor at Road K is “often” busy, so expect company. Wednesday the 5th onwards the quality drops off again. The rest of the second week is a mix of small, choppy, and onshore conditions. The swell energy stays weak to moderate. There’s a tiny window on Saturday the 8th of August morning with a clean 3 ft from the south and an offshore NW wind, but it’s very ordinary. And Sunday the 9th of August morning is similar with a clean 4 ft south swell.
So, the bottom line: the first week is a bust until the 29th. The true standout is the morning of Monday the 3rd of August – big, powerful, clean, and for the brave. The next best are the glassy Friday afternoon on the 31st of July and the clean Tuesday morning on the 4th of August.
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.
