The Lowdown
Alright, this is Rusty. Let's get into it.
Alright, look, I gotta be straight with you. The next couple of weeks are looking pretty flat and grim for the most part. We've got a long stretch of nothing special, so don't be in a rush. The first real chance for a wave that's worth paddling out for isn't until the last day of July, and even then, it's not exactly going to be pumping.
Let's walk through it. The forecast starts with Tuesday, July 21st, and honestly, it's a write-off. We've got a weak, short-period 3ft southerly swell with a period of just 5 seconds and a fresh 19 mph onshore wind. The energy is very weak (52), and it's just poor. This continues through the rest of the week with building but messy swell from the SSW. Wednesday, July 22nd, brings a bigger 8ft swell from the SSW, but the energy is moderate (803) and the wind is a cross-shore mess with thunderstorms. It's just not happening.
We get a bit of a tease on Thursday morning, July 23rd. The swell drops to 4ft from the south with a gentle 9 mph cross-offshore breeze from the NE. The energy is low (224) and the score is marginal, but it's the first clean looking window. It's a beginner spot, very consistent, but that's the only positive. The crowd situation could be an issue, as it's often busy.
After that, it's back to tiny, weak, and choppy for nearly a week. There's a gap of several days with no real recommendations. The swell drops to under 3ft, the wind is onshore or cross-onshore, and the energy is weak. The water temperature is about average for this time of year.
Finally, we get to Friday, July 31st. The morning brings a 4ft south swell with a 7-second period. The energy is still low (144), but the wind is a light 6 mph cross-offshore from the NW. The conditions are clean. It's surfable, but very ordinary. This is the best we've seen in a while.
Then, on Saturday, August 1st, we have a standout moment. The morning is glassy. A 3ft swell from the SSE with a 9-second period, and the wind is a whisper at 3 mph from the north. The energy is low (190), but the conditions are glassy. For a beginner sandbar like Road K, this is the best it's going to get in this entire forecast. The waves will be small, clean, and easy. It's a good session for a learner or a longboard.
After that, it's back to the doldrums. The swell fades into tiny, onshore mush for the rest of the first week of August. By Wednesday, August 5th, we're looking at 2ft and glassy again, but there's no energy (37) and no swell. It's a lake.
So, to wrap it up: the one true standout is the morning of Saturday, August 1st. That's your window. The rest of the time, you're better off doing something else. The forecast can change, but right now, it's a long, flat stretch.
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.
