Table - best surf conditions forecast for Road K over the next 16 days.
Alright folks, Rusty here. Let’s have a look at what Road K has to offer over the next couple of weeks.
Honestly, I’m looking at the whole 16-day window and it’s a pretty grim run for quality surf at Road K. The pattern is noisy, messy, and the swell just doesn’t line up right with any decent winds. For the first week, the window is pretty much a write-off for anything you’d paddle out for. The water temp is sitting around 69°F, which is about 1°F cooler than usual for this time of year – nothing wild, just a touch of a chill.
We kick off from Sunday 12 July with tiny 0.3m SE swell and a cross-on southerly breeze, the wave energy is a weak 35 combined. That is a big, fat zero for any kind of fun. This flat, messy spell hangs around through Monday and Tuesday. On Tuesday the 14th, the swell bumps up to 1.5m from the SSW, and the combined energy jumps to 155 (moderate), but the wind is howling from the SW at 25 mph creating strong cross-onshore chop. It’s a messy windswell, period only 5 seconds. Not surf quality, that's just messy.
The first chance for something clean arrives on Wednesday morning the 15th. That's your best bet. We get a clean window with a cross-offshore breeze from the west at 9 mph. The swell is a modest 1.2m from the SSW, with a period of 6 seconds, a combined energy of 117 (moderate). The waves are surfable, but conditions are still just ordinary. It’s not a standout, but if you’re desperate for a paddle, that Wednesday morning is the only time the lineup looks semi-shapely.
After that, it’s back into the doldrums. From Thursday the 16th right through to the end of the period, it's tiny, weak swell (0.3m to 0.9m) under cross-shore or cross-onshore winds. Friday the 17th and Saturday the 18th morning see clean conditions and offshore winds, but the swell is only 0.3-0.5m. You’d be riding whitewater.
Then around Monday 21 July and Tuesday 22 July, there's a little bump back up to 2-2.0m SSW swell with a moderate energy reading of 155-335, but the winds are cross-onshore and messy every time. The period stays short (6 seconds) and the conditions are poor. That bigger stuff is just lumpy and uninviting unless you’re on a kite.
Frankly, there is no true standout session in this whole run. If you’ve got a surfboard, save your energy for Wednesday morning the 15th. For the rest, it’s a long, quiet stretch.
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.
