The Lowdown
G’day, I’m Rusty. Let’s take a look at what’s coming up at Road K.
Honestly, mate, it’s a pretty bleak stretch ahead. For the next 16 days, there’s no real quality surf on the cards. The swell hangs around in the small, short-period range – mostly under 3 ft – and the wind is almost always cross or onshore, messing up what little bump there is. We’ve got a solid run of poor surf conditions from the start right through until the end of the first week. The water is sitting at 73°, which is a touch warmer than normal for this time of year, but that’s about the only nice thing I can say.
The first decent chance pops up on Monday the 31st of August. It’s not a standout, but it’s the best we’ll see. The morning brings a 5 ft swell from the SSW, with a super short period of 6 seconds, and a moderate breeze from the NW keeping things cross-off and clean. The combined energy is moderate (268). The wave state is clean, but it’s still a very short-period swell, so it’ll be a bit lumpy and lack real push. The break is a sandbar, exposed and very consistent, but with that short period, expect it to be a bit fat and closey. It’s still a paddle, but for a beginner or a longboarder on a small day, it might be worth a go. Crowds are often there, so don’t expect it to be empty.
After that, the whole first week of September is a write-off. Strong winds, messy chop, and the swell is either too small or blown out. The second week offers a few moments, but nothing to get excited about. On Tuesday the 1st of September in the afternoon, we get a 2 ft swell from the SE with a very long period of 14 seconds, and glassy conditions. Combined energy is moderate (171). That long period at a sandbar will likely break straight and close out, so it’s more of a novelty than a session. Then on Wednesday the 2nd, the morning has a 2 ft SE swell with a 12-second period, cross-off wind from the NE at 19 mph, and clean conditions. The combined energy is moderate (205). The swell is small, but the wind is clean. Still, it’s small and average.
Come the 5th and 6th of September, the swell bumps up a bit – 5 ft and 5 ft – but these are from the E with a short period, and the wind is a strong breeze, making it messy and lumpy. The combined energy gets into the moderate to strong range (441 and 548), but it’s not a nice wave. Honestly, with the consistent strong cross-shore wind and the swell size, Road K starts to look more interesting for kite surfing than paddle surfing.
So, for the whole 16-day window, there’s no real standout. The best you’ll get is Monday the 31st of August morning, but it’s a marginal call. Keep an eye on it, but don’t plan your week around it.
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.
