The Lowdown

Alright, let’s break this down. I’ve looked at the full 16-day stretch for Road K, and I’ve got to be straight with you: it’s a rough run. We’ve got a solid sandbar that can fire when conditions line up, but the wind and the swell aren’t playing nice for most of this window. The first real chance to get wet doesn’t even show up until Tuesday the 4th, and even then it’s pretty average. Before that, Sunday and Monday are basically write-offs.

The Long Haul
So, the first couple of days, August 2nd and 3rd, are not worth paddling out. We’ve got onshore winds and small, weak, 7-second swell – just messy and poor. Monday the 3rd gets a bit bigger with some south swell pushing in, but the wind is cross-onshore and it’s stormy. Not the kind of day you’re stoked about.

Tuesday the 4th is the first glimmer. Morning looks clean with a light offshore wind, and there’s a small 4ft south swell with an 8-second period. The energy’s still pretty weak, though, only 191 units coming through. You’ll get some waves, but they’ll be very ordinary. Afternoon drops off again.

Mid-Range Misery
From Wednesday the 5th through to around the 9th, it’s mostly a battle against the wind. The swell stays small, but the cross-onshore and onshore breezes are almost constant, making everything choppy and lumpy. There’s one interesting spike on Monday the 3rd when the swell bumps up to 8ft, and the energy jumps to 599 units. But with that cross-onshore and stormy weather, it’s just not surfable. You’d be fighting a mess. The swell direction is from the south, but the wind ruins it, and honestly, that size and chaos is probably better for the kite crew than us paddle surfers.

Thursday the 6th and Friday the 7th stay in that 5ft range, but the winds are still not your friend. Friday morning is close, with a cross-shore breeze and a slightly better energy reading of 359, but it’s still just marginal. The ocean’s just not giving us a clean face.

A Brief Respite
Monday the 10th is the most interesting day in the first week. The morning has a light offshore wind, the swell is 5ft from the SSW, and the energy is about 150. It’s still not pumping, but it’s clean. That’s a window. If you can get out early, you’ll find some rideable, though not spectacular, surf. Keep your expectations in check. We’re looking at 5ft of south swell, but the period is short, so it’ll be a bit crumbly.

After that, it’s back to the grind. Tuesday and Wednesday are messy again, with bigger winds and more onshore slop.

The Tailing Off
The last few days, from August 13th on, the swell really starts to fade. We’re dropping down to 2ft and smaller. There’s a morning on the 13th with a clean cross-offshore wind, but the waves are just too small to bother with. By the 16th and 17th we’re down to ankle-biters, even though the winds are offshore and glassy at times. The ocean’s basically going flat.

The Verdict
Honestly, there’s no standout swell in this entire forecast. The best window is probably Tuesday the 4th morning for some clean, small waves, and maybe Monday the 10th morning for a little more size. But even then, we’re not talking about a classic session. This is a waiting game. The consistency is actually pretty high for this spot, so it won’t stay flat forever. The forecasts can change, and a better swell could sneak in. But as it stands, you’re better off doing something else.

Water temp is about normal for this time of year, around 71°F.

Stay patient.

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.
