The Lowdown

Alright, surfers, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.

Honestly, this outlook is a tough one. We're looking at a long, dry spell with hardly any decent waves. The first real chance to paddle out doesn't come until Sunday the 22nd of August, and before that, it’s a whole lot of nothing. We’re talking about a gap of nearly two weeks with no surf worth chasing. The water temp is about average for the time of year, so no surprises there.

The only spot that flickers to life is Road K, a sandbar that is very consistent but is only offering a glimmer of hope. The best of a mediocre bunch looks to be Sunday morning the 22nd. We'll see a small, weak swell coming from the south at 4ft, with a short period of 5 seconds. The combined energy is low, just 98 (low energy), so it's not going to have much punch. The real highlight is the wind; a moderate offshore breeze from the northwest will keep the surface clean. It's still a beginner-friendly size, so it's not going to be a standout session, but it’s the only window where the conditions might line up for a mediocre paddle.

The afternoon of the 22nd might see a slightly bigger swell from the south at 4ft, with a bit more energy (106 moderate energy), but the wind turns cross-shore, so it'll be bumpy.

Then we get a tiny pulse on the 24th from the east-northeast at 4ft, but the cross-shore wind will mess it up. The energy is moderate at 182, but the conditions are poor.

Overall, it's a bleak forecast. The break is a sandbar, so with the small, weak swell, it's just not going to offer much. If you're desperate, keep an eye on that Sunday the 22nd morning, but don't hold your breath.

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.
