Table - best surf conditions forecast for Road K over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for Road K.
Honestly, this is a tough stretch. The next couple of weeks are looking pretty bleak for decent waves around here. The water is sitting at 73°F which is a touch warmer than normal for this time of year, but that’s about the only good news. We’re looking at a long, dry spell with nothing but small, weak, and messy conditions for days on end. From Thursday the 9th right through to the end of the first week, wave energy is barely registering, often below 100, with tiny swells and winds all over the place. The surf is just not cooperating. There’s a real gap here with no decent options at all.
The only time things even get a pulse is around Saturday, July 18th. The swell starts to build with moderate wave energy (239), pushing up to 6ft from the SSW, but the wind is a messy cross-shore, making it a lumpy mess. By Saturday afternoon, the swell jumps to 8ft from the SSW with strong wave energy (663), but the period is a short 7 seconds. That kind of size with that wind is seriously ugly, and with the onshore wind, it’s going to be a washing machine. This is really only for experienced, hard-core types who don’t mind a battle. It looks more like a session for the kite crew than a paddle surfer.
After that freak show, Sunday the 19th morning shows 5ft from the S with moderate energy (261), but again, the wind is cross-onshore. The afternoon gets even weirder with a 28 mph cross-offshore wind, which is just howling. We see a bit of 3ft swell on Monday the 20th, but it’s all cross-onshore and choppy.
The second week peters out into the same story. Short period, messy wind, and poor conditions right through to the 24th. There’s simply no standout session, no clean window with good wind and a decent swell. It’s one of those blank runs where you just have to wait it out.
It doesn’t tend to stay this poor for long around here, so keep an eye on the forecasts. But for now, save your wax.
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.
