The Lowdown
Alright, Rusty here. Let’s have a look at Road K. To be dead honest, the next couple of weeks are looking pretty bleak for a proper surf. It’s one of those patches where you’re better off checking the forecast again in a few days because there’s not much to get excited about right now.
We’re starting on Tuesday the 28th of July, and the conditions are just plain ugly. Cross-onshore winds are ruining things, with a tiny 2ft SE swell that has zero push. The energy is weak (85), and it’s choppy. That sets the tone for the next few days. Wednesday the 29th brings a little more size, 5ft SSE, but it’s still cross-onshore and messy. The energy picks up a bit (177), but the quality is still poor.
Now, Thursday the 30th of July morning is the one bright spot in the whole outlook. We get a clean window with gentle offshore winds from the NNW and a 4ft SSE swell. The period is a decent 9 seconds, and the energy is moderate (205). It’s the best the week has to offer, but with only 4ft, it’s small and more of a log or longboard session. The water temperature is 70°, which is pretty normal for this time of year, so no complaints there.
After that morning, it drops off again. Friday the 31st and Saturday the 1st of August have glassy conditions on the surface, but the swell is tiny, around 3ft, and the energy is weak (87 to 94). You can get a wave, but it’s ordinary.
Then we hit a long dry spell. From Sunday the 2nd of August all the way through to Tuesday the 11th of August, it’s mostly poor conditions with small, weak swells. The energy drops into the double digits, and the wind is all over the place. There’s a blip on Tuesday the 11th of August with a 5ft ENE swell, but the wind is cross-shore and the report says poor surf conditions. The energy is moderate (162), but it’s not clean enough to make it worthwhile.
Honestly, this is a quiet period for Road K. If you’re desperate, the Thursday morning is your best chance, but don’t expect much. The rest of the outlook is a write-off.

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.
