The Lowdown
Alright folks, Rusty here. Let's have a look at what Road K is serving up over the next couple of weeks.
Honestly, I gotta be straight with you – it’s a pretty grim run for the foreseeable future. The forecast is a long, dry spell of onshore winds and junky conditions. We’re looking at a solid 12 days of poor surf and choppy, messy water before we even see a glimmer of something decent. The first real chance of a wave comes around Wednesday, 12 August.
The main issue is that the wind is almost always blowing from the south or southwest, which is cross-on or directly onshore for this sandbar setup. The swell is small and weak, barely cracking 3 ft for most of the first week and a half, and the period is short – mostly 6 to 8 seconds. That’s just windswell, no real push or shape to it. The combined energy is weak, mostly well under 100, with a few days in the 100-200 range, but the wind just ruins any chance of it being surfable.
Now, there is a brief window that pops up on Wednesday, 12 August. The morning session shows a light northerly breeze – that's offshore for Road K. The swell is a tiny 3 ft from the SSW, with a period of just 6 seconds, but the offshore wind makes it *clean*. The combined energy is exactly 100, so it's just barely getting into the "moderate" zone. It's called "surfable waves but very ordinary conditions" so keep your expectations in check. This is the only session that gets a score of 1 out of 10, which says it all. It's not a standout, it's just the only one that isn't terrible.
The next morning, Thursday, 13 August, also has a light northerly offshore wind, but the swell drops to 2 ft – it's really small. The afternoon goes completely glassy with no wind, but the swell is down to 2 ft. It might be pretty as a lake, but you'll be struggling to even get a ride.
So, what's the call? There is no real standout. The absolute best on offer is the morning of Wednesday, 12 August. If you are absolutely desperate for a paddle, you might get a few clean, knee-high waves at Road K. For the rest of the 16 days, the wind is just too strong and from the wrong direction. It's a long wait for very little reward. Keep the board in the car and the wax in the wrapper.

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.
