The Lowdown
Alright, Rusty here. Let’s talk about what’s going down at Road K. It’s a sandbar break, real exposed and very consistent. But I gotta level with you: the next 16 days are looking pretty grim. There’s no real standout session, nothing that’s screaming “get in the water.” We’re looking at a long dry spell.
The water temp is 71°F at the start, which is a touch warmer than usual for this time of year – about a degree and a half above average. That’s a nice little bonus, but it won’t save the surf.
Let’s run through it. On Sunday September 6th, the morning offers tiny 2ft swell from the east with a short, weak 7-second period. Combined energy is only 50, so it’s real weak. It’s cross-offshore wind, so it’s clean, but the waves are just too small. The afternoon goes glassy with a 1ft east swell, but energy drops to 28 – totally flat. Monday the 7th morning shows clean 1ft east swell (45 energy) with a nice offshore breeze from the northwest. It’s surfable but ordinary.
That pattern holds: tiny swells, clean conditions, but nothing with any punch. Tuesday the 8th is 1ft. Wednesday the 9th turns choppy with onshore winds and short-period junky 2ft to 3ft swell. That Thursday the 10th things get a bit bigger – 6ft to 6ft from the SSW (energy jumps into the 300s), but the wind is cross-shore and lumpy, so it’s messy. That’s too big for beginners anyway, but with that chop, it’s not even good for experts. The period is only 7 seconds, so it’s weak and wind-affected. That setup looks more interesting for kite surfing than paddle surfing.
From Friday the 11th through to the 21st, it’s a long stretch of surf that’s either too small (under 3ft) or blown out. Most days, the combined energy barely cracks 100. There’s a brief glimpse on Monday the 16th with a 5ft swell from the ENE (Energy of 152) but it arrives with heavy rain and near-gale wind – that’s a no-go. The best of a bad bunch might be Monday morning the 15th: a tiny 1ft SE swell, but with a clean offshore wind from the WNW. It’s barely surfable, but at least it’s clean.
Honestly, there’s one morning that comes the closest to being a pick: Saturday morning, September 7th. It’s a clean 1ft east swell with a 12 mph offshore wind from the northwest (period 10 seconds). The waves are small and weak (energy 45), but the wind is right and the conditions are clean. For a longboard or a foiler, you might get a couple of ankle-biters. It’s not a standout, it’s just the least bad option in a flat spell.
Because this break is very consistent, this run of poor surf is odd but not unheard of. Forecasts can change, but right now, you’re better off waiting for something better. No good surf options to get excited about.
Rusty, signing off.

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.
