The Lowdown
Alright, let me have a look at what we’ve got for Road K over the next couple of weeks. To be straight with you, it’s a pretty grim run. I’m looking at the whole 16-day window and honestly, there’s no proper swell to get excited about. The wave energy is weak, barely cracking 100 on the energy scale most days, and the wind is almost always messing things up. The water is about 72°, which is pretty much average for this time of year, so nothing weird there.
The first real chance of anything even surfable doesn’t show up until Wednesday the 12th of August. Even then, it’s a tiny 3ft swell from the SSW with a short period of 6 seconds. Combined energy is only 50 (weak). The only saving grace is the wind goes glassy that morning, so it’ll be clean. But the waves are small, weak, and ordinary. Not a standout.
We then get a few days of cross-offshore winds from the 13th to the 16th, but the swell is tiny – 2ft to 2ft – with weak energy. It’s clean, but there’s barely a wave to ride. You’d be floating around.
The next little bump comes on Wednesday the 19th of August. The morning shows a 5ft swell from the SSW, period still short at 6 seconds, but the combined energy jumps to 182 (moderate). Winds are cross-offshore from the NW at 19 mph, so it’ll be clean. Swell is small enough for beginners, but that 5ft, with short period, isn’t going to give you much push. The afternoon drops to 5ft with gentler wind. Still, it’s the best we’ve got in the whole run, and it’s not great. For a spot that’s a sandbar and exposed to the S/SSE swell, this setup is pretty disappointing.
Honestly, if you’re a kitesurfer, some of those windy, clean days might look interesting, but for a paddle surfer, this is a lean stretch. The forecast can change, but as it stands, leave the board at home.

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.
