The Lowdown
Alright, surfers, Rusty here. Let's cut through the noise and get straight to what matters for our stretch of coast.
The next couple of weeks are looking like a bit of a mixed bag. We've got a long flat spell coming up, but there's a definite pulse of energy on the horizon that should wake things up. The first real window of opportunity is a couple of days out, so let's break it down.
The early part of the period is a write-off. We're looking at a few days of onshore winds and poor, weak surf. It's not even worth getting the wetsuit on until we get some proper swell and a decent wind.
That changes on Tuesday morning, the 4th of August. This is our first real standout. Road K (sandbar) is going to light up with a clean 5ft of SSE swell. The wind is forecast to be light and offshore (NE at 6 mph), which is exactly what we need on this break. The water temp is currently 71°, which is about average for this time of year. The energy is moderate with a reading of 248, and while the period is a touch on the short side at 8 seconds, the clean conditions will make it very fun, especially for the beginners out there. This is the one to make the most of.
The afternoon stays clean with a glassy spell and the swell dropping to 4ft, but we'll lose a bit of that punch.
Then we go quiet again. From Wednesday the 5th through to the weekend, we're looking at smaller, weaker surf and a return of the onshore winds. There’s a bit of energy mid-week, but it's messy, lumpy, and just not worth paddling out for.
Keep an eye on Monday morning, the 10th of August. The swell is up to 6ft and the energy is strong at 535, but the conditions are questionable. It might be a bit of a mess. However, Monday afternoon is looking like our second standout. The wind swings to a light cross-offshore (NE at 9 mph), the swell cleans up to 5ft, and we're set for some proper waves. The period stretches out to a more powerful 9 seconds, which will give the sandbar some shape. This one's got some punch, so be ready.
After that, it fades out. The rest of the week drops off significantly. There are a few clean but tiny days around the 12th, with some 2ft leftovers, but nothing worth getting excited about. The swell just dies, and we're back to small, weak conditions through the end of the period.
So, in short: grab Tuesday morning, be patient for Monday afternoon, and don't hold your breath for much else. This stretch will test your patience.
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.
