The Lowdown

G’day, it’s Rusty. I’ve been staring at the charts for Road K, and honestly, mate, it’s a pretty grim outlook for the next couple of weeks. We’ve got a massive gap at the start with no real surf to speak of, and it’s not looking like it’ll get much better. The first session worth mentioning doesn’t roll around until Wednesday morning, the 29th of July, and even then, it’s more of a shrug than a celebration.

The whole pattern is dominated by poor surf conditions, with the wind mostly cross-on or fresh, ruining any chance of clean waves. The swell is tiny and weak, with combined energy peaking at 321 (moderate wave energy) on Thursday morning, but the wind is still messy. There’s a long stretch from the 27th of July right through to the 29th where you’re just looking at choppy, lumpy junk. The best bet, if you’re desperate, is the morning of Saturday, 1st August. We’ve got a clean window with a light cross-offshore breeze from the NNE at 9 mph, and the wave comment says “surfable waves but very ordinary conditions.” The swell is a pathetic 2 ft from the south, with a short period of 8 seconds and combined energy of just 104 (weak). It’s small, gutless, and really only a paddle for a beginner on a foamie.

The standout, if you can call it that, is the morning of Thursday, 30th July. It’s the only time the swell nudges up to 5 ft from the SSE, with a period of 9 seconds, giving a combined energy of 321 (moderate). The wind is a gentle cross-shore from the SW at 9 mph, which is just about okay, but it’s still described as “marginal surf forecast or questionable tide conditions.” That 5 ft is right on the edge of being too big for beginners, but it’s not big enough for the experts to get excited. The water temp is about 70°F, which is a touch cooler than average for this time of year (anomaly of -2°F), so not a big deal.

After that, it’s a slow fade. By the second week, from the 5th of August onwards, the swell drops to 1 ft or 2 ft, with south or southeast winds making it a cross-on mess. There’s a brief moment on the morning of Tuesday, 4th August, with clean conditions and a cross-offshore breeze from the WNW at 9 mph, but the swell is only 2 ft and weak (combined energy 84). The very end of the outlook, on Monday morning, 10th August, has a glassy wind from the east at 3 mph, but again, the swell is a tiny 2 ft with a period of 6 seconds, and combined energy of 37 (weak). It’s flat, mate.

Honestly, there’s no true standout here. The only break on offer is Road K, a sandbar that’s very consistent but exposed to the swell. It’s often crowded, but with this forecast, the crowds will be thin. For a surfer, the whole 16-day window is a write-off. If you’re a kite surfer, the brisk cross-on winds on the 28th of July (19 mph) and the 2nd of August (16 mph) might make it more interesting, but for a paddle, it’s a hard pass. Forecasts can change, but this one looks stubborn.

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.
