Alright, let me tell you straight up, it’s been a bit of a flat spell for Road K. We’ve got a long quiet run here, and there’s nothing that’s really going to get the heart pumping for the first week or so. The waves have been tiny and the wind hasn’t been playing ball at all for proper surfing.

Let’s start with the early window. Friday the 3rd of July, we’re looking at a tiny 3ft swell from the SSW, but with a weak energy reading (65). The morning has a light cross-off breeze, so it’s clean, but it’s just too small and weak to be worthwhile. The afternoon gets messy with a strong cross-onshore wind, so that’s a write-off.

Saturday the 4th and Sunday the 5th are pretty much flat as a pancake – we’re talking 1ft to 1ft. The energy is next to nothing, under 40. It’s the kind of weekend you don’t even bother loading the board on the car. That quiet run carries on through Monday and into Tuesday morning, with only a slight bump in energy.

Now, Tuesday the 7th of July afternoon is where we get our first proper sniff of hope. The swell bumps up to 5ft from the ESE, and the energy climbs to a moderate 209. The wind goes glassy, dead calm. This is the first time we see the conditions come together for "good surf conditions". For a sandbar that’s very consistent, it’s a promising little window, but it’s small comfort after so many days of nothing.

The big standout doesn’t come until the second week. Saturday the 11th of July morning is looking like the best of the bunch by a long stretch. We’ve got a solid 4ft swell from the south (S), with a combined energy hitting 246 – that’s moderate but building. The wind is a light offshore from the NE, so the faces will be clean. Road K is exposed to the swell, and with SSE being the optimum direction, this southerly swell is a great match. This is your day to get wet. It will be clean, consistent, and have enough push to be fun.

Unfortunately, the outlook after that goes back to mediocrity. The winds shift onshore or cross-shore again for the rest of the second week, and the energy drops off. By the 15th of July, we see a bigger bump in size – 6ft to 7ft – but with fresh onshore winds and a short, choppy period of 6 to 7 seconds, it’s going to be a mess. For a beginner-friendly sandbar, that’s too much size and too much chop for a fun session. It’ll be more of a kite-surfing proposition than a clean paddle session.

So, to sum it up: the first week is lean, with a brief glassy window on Tuesday the 7th afternoon that’s worth a look if you’re desperate. Your real highlight is the morning of Saturday the 11th of July. That’s the one to circle on the calendar.

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.
