The Lowdown
Alright folks, Rusty here with a look at what we’ve got coming down the line at Road-K.
It’s gonna be a real mixed bag, and honestly, a bit of a frustrating watch for a while. We’ve got some swell pulsing through, but the winds just can’t seem to get it together. There’s a big gap of slop and onshore junk right from the start, so don’t even bother paddling out until we get through the first week.
Things finally look like they’re trying to turn around on Thursday morning, the 29th of July. We get a decent 4ft swell from the south with a fresh offshore wind from the northwest that will be scrubbing the lines clean. The combined energy is moderate at 176, but that offshore flow makes all the difference after days of crud. That’s your first real chance, but the conditions are still described as poor, so it’s more of a hopeful paddle than a standout.
Our only real standout comes late in the window. On Monday morning, the 3rd of August, we get another 3ft south-east swell, but the wind goes light from the northwest (6 mph), leaving the surface clean. The combined energy is still moderate at 142. This is a window for a beginner-friendly wave as the swell is under 5ft, and with clean conditions, it’s your best shot for a fun slide. It’s not big, but at Road-K, a clean wave is a good wave.
Then, the next morning on Tuesday the 4th of August, the wind goes totally glassy at dawn. We're looking at a tiny 2ft south-east swell (energy 61), but with zero wind, the surface will be like butter. You’ll have to work for it, but if you want a longboard or a fish to yourself while the sun comes up, that’s the session to aim for.
Overall, it’s a long stretch of average to poor conditions, with just those few clean mornings at the start of August being the only things worth setting the alarm for.
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.
