Updates in hr min s Forecast update imminent
G’day, Rusty here. Look, I’ll be straight with you – the next couple of weeks at Road K are mostly a frustrating story of close-to-nothing surf, with one big exception right at the end that could make it all worthwhile. For a spot that’s normally pretty consistent, there’s a long, quiet gap before we finally see some proper energy.
The water temp is sitting at 73°F, which is a solid 4°F warmer than what we’d expect for this time of year – feels like a warm bath out there.
We kick off with a real struggle. Tuesday the 7th has a poor 5ft easterly windswell with a short period of 6 seconds and a fresh 22 mph cross-offshore wind. The combined energy is a weak 156, making it messy and not worth paddling out for. Wednesday the 8th morning offers a slight tick up with 5ft east swell at 7 seconds and a light 6 mph cross-off breeze, but the energy jumps to 431 and the forecast says “expect good surf conditions.” It’s still pretty average though – not the standout.
From Thursday the 9th through to Friday the 17th, it’s a long, flat run of tiny waves, mostly under 2ft, with a lot of cross-onshore winds. The combined energy rarely cracks 100, and most sessions are rated as poor. There’s a brief moment on the morning of Friday the 17th where the wind goes glassy and it’s clean, but with only 2ft of 8-second swell, there’s barely a ripple.
Now, here’s where it gets interesting. Way out on Saturday the 18th morning, a proper southerly groundswell arrives. The swell height jumps to 6ft from the south, with a period of 8 seconds, light offshore wind from the west at 6 mph, and a combined energy of 520. That’s moderate-strong energy, and with offshore conditions, the break should be clean and lined up. That afternoon it pushes up to 8ft from the south-southwest, but it swings onshore and becomes a bit of a mess for paddle surfing.
Sunday the 19th morning is the real standout. We’ve got 6ft southerly swell with a period stretching to 9 seconds, light offshore wind from the northwest at 6 mph, and a combined energy of 508. Offshore wind plus a solid groundswell and moderate energy? That’s a proper session waiting to happen. If you’re an experienced surfer, this is your window – the 6ft is clean and punchy. That afternoon, a 12 mph cross-onshore messes it up.
Monday the 20th drops off again with 4ft and a cross-shore wind, and the rest of the period fades to flat, weak swell with onshore winds.
So look, the highlights are clear. Saturday 18th morning and Sunday 19th morning are your best shots. The swell directions are south and south-southwest, which matches Road K’s optimum of SSE well enough to produce good shape. The offshore wind on those mornings will leave the surface clean and the sets will have decent push. Just don’t expect beginners to have a good time on the 6ft or 6ft – that’s expert territory.
You’ll need to wait out a long, flat first week, but if you’re patient and free on that second weekend, it’s going to be worth the wait.
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.
