Alright, gang, Rusty here. Let’s break down what Road-K has coming up. It’s a lean 16 days, to be honest. This sandbar spot usually picks up swell, but the next few weeks are mostly a bust. Water temp is 73°F right now, a solid 4°F warmer than average – you’ll notice that warmth when you hit the water.

Starting Sunday July 5: tiny 1ft SE swell, 8-second period, cross-on wind – total chop. No go. Monday July 6 gets a bump to 5ft ESE, but it’s blowing 22 mph cross-on and lumpy – still terrible. Tuesday July 7 sees 6ft E swell with cleaner cross-off breeze, but period is only 7 seconds and energy moderate (274), yet the reports still call it poor. Not worth it.

First half-decent window is Wednesday July 8 morning: light offshore from NNE, 3ft E swell at 7 seconds, clean but weak energy (117). Surfable but nothing special. That afternoon turns choppy again.

Thursday and Friday stay weak. Friday July 10 gives two better slots: morning has 3ft SSW swell with light NNW offshore, clean; afternoon even smaller 2ft S swell with moderate offshore, also clean. Still small, period only 6 seconds, energy low (56–71). Saturday July 11 morning might be the top pick: 3ft S swell, 8-second period, gentle NE cross-off, clean, and energy ticks up to 141 (moderate). That’s about as good as it gets – small but rideable for a beginner with clean conditions.

From Saturday afternoon onward it’s back to poor – onshore, cross-onshore, lumpy, and tiny. A little energy pops around July 14 (Tuesday) with 4ft SSE swell but fresh cross-onshore winds – still poor. The rest of the two weeks is a mix of small, short-period junk and crummy wind. Nothing over 5ft until the end, and even then quality is poor.

So no true standouts. Best you’ll get is a few sessions of ordinary, clean, small waves – fine for beginners. Experts, save your energy. Forecasts can shift, but right now it’s a quiet, long stretch.

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.
