Table - best surf conditions forecast for Road K over the next 16 days.
Alright mates, Rusty here, checkin' in on the Road K scene for the next couple of weeks.
I'm gonna level with you, the first part of this forecast is a bummer. We're lookin' at a real quiet spell, a good week and a half with basically no surf worth paddlin' out for.
Friday the 10th is a bit of a head fake. There's a tiny 2ft south swell, but it's got a short 5-second period, so it's weak and crumbly. The water is a touch colder than normal at 68°, and while the morning has a light offshore breeze, the energy is real low (55). It's rideable, but just barely.
From Saturday the 11th on, it's a total washout. Nasty cross-shore winds, choppy water, and tiny, weak waves. Tuesday the 14th sees a spike to a 5ft southwest swell, but it's gettin' thrashed by a 22 mph cross-shore wind, makin' it a churned-up mess. That's kite-surfing weather, not surfin' weather.
We finally get a flicker of hope around the 21st of July, but the real highlight is shaping up for the morning of Wednesday the 22nd. That's the one. We've got a clean 5ft swell from the east, with a light offshore breeze from the NNW. The combined energy hits 299 – that's a solid, moderate push of power. The waves will have some grunt, but at 5ft, it's getting a bit much for the beginners. The offshore wind means the faces should be glassy and clean. This is the only real window in the whole 16 days, and it's a good one.
The last few days on the 25th have a bit of south swell, but the conditions are only so-so. The window is basically shut.
So, the long and short of it is: wait it out. The only true standout is the morning of Wednesday the 22nd at Road K with that 5ft east swell and clean offshore wind. That's your shot.
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.
