The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Road K over the next couple of weeks. Gotta be straight with you – it’s a pretty bleak stretch. The forecast is stuffed with lumpy, choppy, or just plain messy conditions, and the swell is rarely doing us any favours.
We’ve got a long dry spell to start. The first real chance to even think about paddling out doesn’t come until Friday morning, the 4th of September. That’s a full three days of waiting. Even then, it’s not much to write home about. We’re looking at a tiny 1ft swell from the SE, with a period of 8 seconds. The energy is weak (40). The only reason it’s worth mentioning is that the wind is glassy. That’s a major positive, but with waves that small, you’ll be fighting for every ride. The water temp is about average for this time of year.
After that, it’s back to the same old story. Through the weekend and into the start of the next week, the swell stays small and the wind swings around, mostly cross or cross-onshore, keeping things choppy. There’s a brief moment on Monday morning, the 7th, with a 2ft, 11-second period swell from the east and light offshore winds from the NNW. That’s a cleaner window, but the energy is still low (87) and the surf is very ordinary.
The standout period, as far as anything can be a standout here, looks like Thursday the 10th of September. We’ve got a slightly bigger swell pushing in, 5ft from the SW with a 7-second period. The combined energy jumps up to a moderate 327. However, the wind is a gentle cross-onshore with a risk of thunderstorms, so it’s going to be a bit messy. It’s the biggest swell in the whole run, and Thursday morning has the best of it, but it’s still not clean.
Later on, on Thursday the 17th of September, we see a 5ft swell from the east with a 6-second period and moderate energy (181). The wind is a clean cross-offshore from the west, which is promising. But that’s a long way out, and the period is short, so keep your expectations in check.
Honestly, if you’re desperate, the Friday morning glass-off on the 4th is your best bet for a clean, if tiny, session. For anything with a bit more push, the Thursday the 10th is the pick, but don’t expect perfection. The crowds at Road K can be a problem often, so even on a poor day, you might have company.
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.
