Table - best surf conditions forecast for Road K over the next 16 days.
Alright, Rusty here. Let me tell you what's on the menu for the next couple of weeks at Road K.
Right off the bat, we’re sitting through a flat spell. The first couple of days are a write-off – weak, short-period slop, and onshore winds making a mess of things. Hang loose, it’s gonna be quiet until Wednesday the 15th.
That Wednesday morning, the 15th of July, is our first real chance. We’ve got a clean 1.3m swell rolling in from the SW with a gentle cross-offshore breeze. The combined energy is a solid moderate 217, and the water temp is about average for this time of year. It’s a small window though, and the afternoon drops off. Not a standout, just a decent little session to get wet.
The real standout is way out there, on Friday the 24th of July. That afternoon, the stars align. A clean 1.8m groundswell from the south, with a period of 8 seconds, pushes in here. The wind goes light and cross-offshore, making for really clean conditions. The combined energy is a chunky 463, which means there's plenty of push. It's a bit of a wait, and long-range forecasts always have a bit of guesswork in ‘em, but if it comes together, that’s the day to circle on the calendar. Because the swell is over 1.5m, this is not for the beginners.
The following Saturday the 25th has some size too, with 2-2.3m swells from the south, but the wind swings onshore and choppy, so it won't be as clean. That Friday is your target.
So, to be straight with you: we’ve got a long dry spell, a brief chance on the 15th, and then a standout potential on the 24th. Keep your eyes on that Friday. The rest is just wind and small waves. It’s a sandbar spot here at Road K, and when it’s clean, it’ll be worth the wait.
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.
