Updates in hr min s Forecast update imminent
Alright, Rusty here. Let’s break down what’s happening at Road K over the next couple of weeks.
Truth is, it’s a pretty slow stretch for this spot. For the first week and a half, there’s just nothing worth getting wet for. We’ve got a long gap of poor surf from Friday the 3rd through to late in the week starting the 7th, with tiny swell and messy winds. Water temp is running about 69°, which is normal for this time of year – pretty average.
The first real chance comes on Saturday the 11th of July. Saturday morning we get a moderate offshore breeze from the NNW and a 4ft swell from the S, period around 8 seconds. It’s clean, with moderate energy. The standout, though, is Saturday afternoon. The wind drops right out – glassy conditions – and that S swell pushes up to 4ft with a 9-second period. Energy is solid (265). That’s the best on offer across the whole forecast. Clean, lined-up waves, a fun size. That Saturday afternoon is your window.
After that, it goes quiet again. Sunday the 12th is blown out, and we’re back to poor surf until Wednesday the 15th, where the swell drops off to nothing. The 16th and 17th are tiny and messy, with strong onshore winds on the 17th – that’s more kite-surfing weather than paddle-surfing.
Then, late in the period, on Saturday the 18th of July, a bigger pulse arrives. A 6ft SSE swell with an 8-second period rolls in, and the energy is strong (414 to 453). The winds are clean, cross-off from the WNW. But the notes say marginal conditions or questionable tide, so it might be a bit finicky. Still, for experienced surfers, if the tide lines up, it could be worth a look. That size is over 5ft, so beginners should probably stay on the beach.
So, to sum it up: the standout is Saturday the 11th of July afternoon – glassy, 4ft from the south, good energy. The long-range Saturday the 18th has size and clean wind, but tide might be the catch. Other than that, it’s a quiet run for Road K.

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.
