The Lowdown
Alright, let’s have a look at what’s on offer for Road K over the next couple of weeks.
Honestly, mate, it’s a pretty grim stretch ahead. The whole 16-day window is one long dry spell with really nothing to get excited about. We’re looking at a solid run of tiny, weak, messy surf, and most of it is blown out by onshore or cross-shore winds. You’ll be waiting a long time for anything rideable, and even then it’s only just surfable, not good.
The first real day where it’s even worth paddling out doesn’t come until Wednesday, August 26th. Even then, it’s tiny – just 1 ft from the southeast, with a period of 10 seconds. The energy is weak (65), but at least the wind is light offshore from the WNW in the morning, so it’ll be clean. That’s the absolute best we’ve got, but it’s still only a 1/10 for quality. Definitely not something to rearrange your week for.
After that, the rest of the month and into September is mostly more of the same: small, choppy, and onshore. There’s a faint glimmer on Thursday, September 3rd, with a clean, offshore wind from the NNW, and again just 1 ft from the southeast. The energy picks up a little (57–77), but the waves are still barely there. Then Friday, September 4th, gives us a gentle offshore in the morning with 2 ft from the SSW, period of only 5 seconds. Again, it’s surfable, but nothing to write home about.
So the standout – if you can even call it that – is Wednesday, August 26th, first light. Clean, offshore wind, and your best shot at a few tiny, clean lines. The water temp is about average for this time of year, nothing unusual there.
Overall, this is a classic flat spell for the area. When it’s this quiet, you just have to wait it out. Forecasts can always turn around, but right now, it’s looking like a long wait for any real swell.
Stay patient.
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.
