The Lowdown

Alright, Rusty here. Let's talk about what we've got on the calendar for the next couple of weeks.

Honestly, it's a slow start and a long wait. There's a real lull in the surf for the first few days, and we're looking at a stretch of small, wind-affected conditions that just won't be worth the paddle out. The first real glimmer of anything surfable doesn't show up until Thursday morning, the 30th of July, and even then it's borderline.

The only spot that's on the radar here is Road K. It's a sandbar that's very consistent, exposed to the SSE swell, and it's a beginner-friendly wave. The water temperature is sitting at 70°, which is pretty normal for this time of year.

Let's walk through the options. The entire first week is a write-off. Tuesday and Wednesday are just a mess of cross-onshore wind and poor surf. The swell is there, but it's wrapped in bad wind, so it's a no-go.

Thursday morning, the 30th, sees a bit of a change. The wind goes light and cross-offshore from the north, cleaning things up. The swell is a modest 4 ft from the SSE, but with a period of 9 seconds, it's got a bit of shape. The combined energy is moderate (214). It's a "marginal" call, but that's the first window where you might find a few clean ones if you're desperate.

Friday morning, the 31st of July, is a better bet. Light offshore wind from the north, with a 3 ft SSE swell at 9 seconds. The energy is still moderate (130). It's "surfable but very ordinary." The afternoon gets even better, with glassy conditions and a 3 ft SSE swell. If you're a beginner, this is the highlight of the week—glassy, clean, and small.

After that, it really drops off again. The wind swings onshore and the swell gets weak and short-period. There's a long gap from Friday afternoon the 31st all the way through to Tuesday morning, the 4th of August, where conditions are poor or just too small. Tuesday morning offers a flicker of hope with a clean 3 ft S swell and light offshore wind, but it's still very ordinary.

The second week is a total bust. From the 5th of August onwards, the swell is tiny, the period is short, and the wind is a cross-onshore mess. The combined energy drops into the double digits, which is weak. The afternoon of the 9th of August is a classic example: 0.9 ft swell with a 19 mph cross-onshore wind. That's not surf, that's a washing machine. For a beach or sandbar setup like this, it's more interesting for the kite surfers than anyone with a paddle board.

So, to sum it up: the best bet on offer is Friday morning, the 31st of July, at Road K. Clean, light offshore wind, with a 3 ft SSE swell. It's a beginner-friendly wave, but it's small and ordinary. If you're looking for anything bigger or better, you'll be waiting a long time. The forecast can change, but as it stands, we've got a big blank run.

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.
