The Lowdown
Alright, surfers, Rusty here. Let’s be real with you about the next couple of weeks. We’ve got a window that’s mostly a whole lot of nothing, with a couple of tiny flickers of hope way down the line. Don’t get too fired up just yet.
The immediate outlook is grim. We’re looking at a solid stretch of days where the surf just isn't happening. From the 28th of August right through to the 4th of September, the swell is tiny and the wind is all over the shop. You’ll see a few knee-high wobbles, but the onshore and cross-shore breezes are going to chop it all to bits. The energy is weak, with values mostly under 110, and it’s just not worth getting the board wet. It’s gonna be flat and messy.
There’s a small tease on the morning of Saturday the 5th of September. The wind goes glassy and we get a hint of an easterly swell pushing 2ft. It’s still pretty weak with an 98 combined energy, but that glassy morning might just give you a couple of clean dribblers if you’re desperate. Don't expect much. Later that day and into the 6th, the swell bumps up a touch to 3ft, but the onshore wind comes back in and ruins it. The energy starts to build though, sitting around 180 on Sunday the 6th, which is at least something.
Then we go quiet again. Monday the 7th sees some proper offshore wind, but there’s no swell to speak of. It’s clean, but it’s flat. This blank stretch really drags on.
We finally get a little pulse of life on the 10th of September, a Thursday. The swell pushes up to a bit over 3ft, with the energy getting to 148. A light offshore wind in the morning will make it look clean, but the period is a short, weak 7 seconds. It’s not going to be epic, but it’s the first surfable option we’ve seen in over a week. The break here, Road K, a sandbar setup that’s very consistent but usually needs a bit more juice, might just offer up some soft, crumbly waves. It’s still pretty average, but it’s something.
Honestly, the standout window, if you can call it that, is the 9th and 10th of September. There’s a decent jump in the combined swell energy on the 9th to 100, with the swell height hitting 4ft, but the period is a terrible 5 seconds. That’s just wind slop. The better bet is the morning of the 10th, with that 4ft of south swell and clean offshore conditions. It’s still only 1/10, but it’s the best of a bad bunch. For what it’s worth, the energy finally gets into the 100s, but it’s just a weak, short-period pulse. It’s not going to be any good for a beginner, as it’s over 2ft but under 5ft so not too big, but the quality is just poor.
The water temp right now at Road K is about average for this time of year. No big anomaly to talk about.
So, in short, we’ve got a long stretch of poor conditions. The first real chance of a wave is on the 10th, but it’s not going to be memorable. This is a case where the forecast can only get better, and I’d keep an eye on things, because it can’t stay this poor for long.

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.
