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 cookin’ for Road K.
Right off the bat, I gotta tell ya, the first week is a bit of a struggle. We got a few mornings where the waves are small and clean, but nothin’ really gets the heart pumpin’. The water is sittin’ at a balmy 73° which is much warmer than normal for this time of year, so at least you won’t need a thick suit.
The real story here is the wait. For nearly two weeks, it’s a lot of lumpy, choppy, cross-on junk with tiny swell. You’ll see a few glassy mornings with waist-high waves, but the energy is weak – we’re talkin’ combined energy readings down in the 40s and 50s. Not worth paddlin’ out for unless you’re _really_ desperate for a trim.
Now, mark your calendars. On Monday the 20th and Tuesday the 21st, things finally flip. Monday morning the 20th is the standout of the whole run. We’ve got a solid 10 ft groundswell pushin’ in from the S with a period of 10 seconds – that’s moderate groundswell energy (2413), plenty of grunt. The wind is a clean offshore from the NNW at just 6 mph, makin’ it glassy. This is excellent surf for experienced surfers only – that’s big, powerful stuff, not for the faint-hearted. Tuesday the 21st morning cleans up a bit more, with the swell droppin’ to a still-punchy 5 ft from the S, light offshore N wind at 3 mph, and combined energy at a solid 306. That’s a great session for the stronger intermediate crew.
So, really, the best is right at the tail end. Get some rest, be patient, and be ready for that Monday the 20th morning session if you know what you’re doin’.
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.
