The Lowdown
Alright folks, Rusty here. Let’s take a hard look at what’s coming up for the next couple of weeks at Road K. I’ll be straight with you – this stretch is gonna test your patience.
We’re looking at a long, dry spell to kick things off. From now until the end of the first week, it’s mostly a write-off. The swell energy is weak, often under 100, and the wind just won’t play ball. There’s a small glimmer on the morning of Wednesday, July 22nd, when we see a jump in size to 6 ft from the south, with a clean, cross-off wind. The energy reads a solid 614, which is a proper pulse, but the swell period is a short 9 seconds, so it’ll be a bit lumpy and fat. The wind is offshore, so if you’re desperate, it’s the best of a bad bunch, but I wouldn’t call it a standout.
Honestly, the only true standout in this whole 16-day window is the morning of Tuesday, July 28th. This is the one to circle on your calendar. We’ve got a solid 7 ft swell from the south, and the wind is a light cross-off from the west at 9 mph. The water temp is about average for the time of year at roughly 70 °F. The combined energy is a proper 426, so there’s some grunt in the water. The period is 7 seconds, so it’s a bit short, meaning it won’t be the cleanest, long-period groundswell, but with that wind and size, Road K will have some clean, punchy walls. This is the one day where all the stars align for a proper session.
Before that, the morning of Wednesday, July 22nd, has some size at 6 ft, but it’s not as clean. And the afternoon of Wednesday, July 29th, offers clean waves at 4 ft, which is a nice little end to the run, but nothing to write home about.
The rest of the time? It’s a whole lot of nothing. Cross-shore winds, messy chop, and weak swell. If you’re a kite surfer, you might get a look on some of those windier days, but for a paddle surfer, it’s a tough watch.
So, to sum it up for ya: wait it out for Tuesday morning, July 28th. That’s your session.
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.
