The Lowdown
Alright folks, Rusty here. Let’s have a look at what Road K has in store for us over the next couple of weeks. I gotta be straight with you – the start of this run is a bit of a bummer. There’s a big gap with nothing worthwhile, so we’ll be waiting a while for the first real chance to get wet.
The opening days from Thursday the 16th right through to the end of the week are a write-off. Tiny waves with junky short-period energy, and the wind is all over the shop – mostly cross-shore and cross-onshore. It’s messy, weak, and not worth paddling out for. You’re looking at a solid few days of no recommendations there.
The first sign of life shows up on Sunday the 19th. We get a jump in swell to around 6 ft from the SSW, but the energy is moderate at best (312). It’s still a bit messy though, with cross-offshore winds in the morning and the tide might be playing games. It’s a marginal call, not a standout.
Now, pay attention to Wednesday the 22nd. That’s our first real highlight. The morning sets up nicely with a clean 5 ft swell from the S, a period of 9 seconds giving it some decent shape, and a gentle offshore wind from the N. The combined energy hits a moderate 340, so there’s some push. The water temp is sitting at 21°, which is about average for this time of year, so no surprise there. The wind is offshore and clean – that’s a major positive for Road K, a sandbar exposed to the swell. Just a heads up, the crowds here can be often, so if it’s looking good, don’t expect to have it to yourself. That Wednesday morning is the best bet of the whole outlook.
After that, it fades again. We go back into a long run of poor to ordinary conditions right through the end of July. There’s a glimpse on Friday the 31st with a 4 ft swell and offshore wind, but the period is a short 6 seconds, so it’ll be weak and won’t have much grunt.
Overall, it’s a lean period. The window is narrow. If you can get out on the morning of Wednesday the 22nd, do it. That’s your one true standout. The rest is a waiting game.

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.
