Imperial version
Alright folks, Rusty here. Let’s be real – this forecast for Road K is a tough one. There’s a massive blank run that stretches from now all the way through the first week. Don’t even bother waxing up until we get past the middle of the month. The wait is nearly two weeks long for anything that even sniffs like a wave.
The first real glimmer of hope – and I mean a tiny glimmer – comes on Friday, July 10th. We’ll see a 3 ft swell from the SSW with a light offshore cross-off breeze. It'll be clean, but the swell energy is weak (210). It’s a “poor surf conditions” scenario, but hey, at least the wind is right. The water is running at a very warm 73°, which is 4° above the norm for this time of year—that’s much warmer than usual. You’d be in boardies.
The only day that even gets a "good surf conditions" nod from the data is that Friday morning. After that, the wind turns on again and messes things up. The crowd situation at Road K can be busy (“often” levels), so if you do brave that Friday session, the early morning glass-off is your window.
Things get a bit more interesting way out on Sunday, July 19th. We get an 8 ft SSW swell with a period of 8 seconds. That’s some serious combined energy – a massive 1674. It’s a lot of juice, but that period is short, so it’ll be a bumpy, messy beast. The wind is cross-onshore, making it marginal. For expert chargers only, and it’s a long-range call, so take it with a grain of salt. The 6 ft on the Sunday afternoon is the better bet for the brave.
Honestly, for sixteen days, this is a grim run. The surf quality is ordinary at best. If you are just desperate, that Friday 10th morning is the only one that doesn't feel like a chore.
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.
