The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for Road K over the next couple of weeks.
Honestly, it’s a pretty grim run for the most part. The first week and a half is mostly a write-off. There’s a lot of onshore and cross-shore chop, plenty of wind, and the swell energy is weak and messy. We’re talking about a long stretch from the 15th right through to the 19th with nothing worth paddling out for. The wind is just all over the place, and the wave heights are either tiny or blown out.
The water temp at Road K is sitting at 71°F, which is pretty much bang on average for this time of year, so nothing unusual there.
The first real glimmer of hope comes on Monday the 20th, in the morning. The wind goes glassy, just a whisper from the WSW at 3 mph, and the swell is a clean 4 ft from the S, with a period of 9 seconds. The combined energy is moderate at 278, and the conditions are looking glassy. This is your standout window. It’s not huge, but it’ll be clean and fun. The crowd factor is “often” here, so expect company, but for a morning like that, it’s worth it. The swell direction is S, which is close to the optimum SSE for this sandbar, so it’ll hold some shape.
After that, it’s back into the doldrums. The wind messes things up again from the 20th afternoon, and the rest of the week through to the 30th is a mix of very small, onshore, or choppy slop. There are a couple of moments on the 28th and 29th mornings where the wind is light or glassy, but the swell is tiny – only 2 ft – and the energy is weak. It’s surfable for a beginner on a foamy, but it’s not what I’d call a proper surf.
So, the bottom line: if you’re keen, set your alarm for Monday the 20th, early. That’s the only real light in this tunnel. Everything else is a waiting game.

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.
