The Lowdown
Alright folks, Rusty here. Let’s talk about Road K. Gotta be straight with you – the next couple of weeks are looking pretty flat and frustrating around here. The surf forecast is a long, quiet stretch, so don’t be in a rush to wax up.
The combined swell energy is weak, mostly under 100 and often down in the 30s and 40s, so there’s just nothing pushing through. We’ve got a solid gap from now until late in the second week. For the first 14 days, every single session is marked as poor surf conditions. There’s a bit of a pulse trying to show up on the 21st of August, but even then, it’s just barely surfable.
The water temperature is sitting at 72°, which is exactly average for this time of year, so no surprises there.
The first real chance you’ll have to paddle out is on Friday, the 21st of August. The swell picks up to 4 ft from the SSW with a short period, but the wind goes glassy, so the surface will be clean. The combined energy is still only moderate at 131, so it’s not powerful. The waves are surfable, but the conditions are described as very ordinary. For a spot that’s very consistent, this is a pretty poor showing.
Saturday the 22nd of August has a little bit left – 3 ft from the S – but the wind is glassy again in the morning, so it’s clean. The energy is even lower, though, at 85. Still, it’s a quiet, clean option if you’re desperate to get wet.
Honestly, folks, there’s no standout here. The only thing worth mentioning is that the 21st has the biggest swell with glassy wind, but the quality is still poor. For a stretch that long, it’s a frustrating run of blank days. That’s the way it goes sometimes.
Stay patient, and keep an eye on the charts. Things can change.
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.
