Right then, let’s have a look at what’s on the cards for Road K over the next couple of weeks. I’ve gotta be straight with you, it’s looking pretty grim for a while. We’ve got a real dry spell on our hands, so don’t be in any rush to grab your board just yet.

Alright, the first half of the period, from Sunday the 12th right through, well, pretty much all of the first week, is a write-off. The swell is tiny, well under 2ft, and the winds are a mess – cross, cross-on, onshore, you name it. There’s no energy to speak of, with the combined swell energy struggling to crack triple digits. Even when Thursday the 16th morning shows a bit of a cleaner window with a cross-offshore breeze, there’s just no swell to work with. Friday the 17th morning has some gentle offshore wind, but again, the swell is a paltry 2ft from the S. It’s just not happening.

Things finally start to look a little more interesting heading into the second week. Sunday the 19th brings a jump in size, with a 6ft E swell rolling in by the morning, and the combined energy kicking up to a moderate 291. However, the cross-shore wind will be chopping it up. By the afternoon, the swell pushes to 7ft from the E, and the energy jumps to 444, but the conditions are still just “marginal.” Monday the 20th morning has a 5ft E swell with a fresh cross-offshore breeze, so it’ll be clean, but that’s a fair amount of power for a sandbar. The bigger stuff comes in on Saturday the 26th and Sunday the 27th, with swell hitting 7ft to 8ft from the S and SSW. The energy figures are huge – 784 and even 1208 on Sunday the 26th afternoon – but the winds are strong and cross-onshore, making it a lumpy, messy mess. That kind of power with onshore wind is more for the kite crew than for a paddle surfer.

The only real bright spot I can see is Monday the 27th morning. We’ve got a 4ft S swell with a period of 8 seconds, a light offshore wind from the NNW, and the note says “clean.” The combined energy is a moderate 167. It’s not a massive swell, but for this stretch, it’s the best we’re going to get. The light offshore wind is a massive positive – it’ll keep the surface glassy. Just be aware that at 4ft, it’s still a manageable size for most.

The water temp on the 12th was 69°, which is about 1° cooler than average for the time of year. Nothing too wild there.

Honestly, it’s a lean run. For a spot that’s very consistent, this is an unusually blank period. Forecasts can change, so keep an eye on it, but for now, I wouldn’t be making any plans.

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.
