The Lowdown
Alright, Rusty here. Let’s break down the outlook for Road K. We’re looking at a long, hard wait before the surf finally shows up. For the first two weeks, it’s mostly a waste of time with blown-out, gutless conditions.
The pattern is ugly. The wind is almost always cross or onshore, and the swell is small, weak, and short-period. The combined energy is mostly in the double digits (80-90, 60-70), and even the higher readings like 824 on August 3rd come with a stormy 25 mph cross-onshore wind that makes it a kite-surfing day, not a surf day. The water temp is 72°F, which is dead average for this time of year.
The biggest thing to know is the gap. There is nothing worth paddling for from now until the morning of Monday, August 18th. That’s a solid two-week stretch of nothing.
Monday, August 18th is the only real standout. The morning is the best of the whole 16 days. We get a clean, gentle offshore wind from the north, and a 6 ft swell from the southwest. The combined energy is a moderate 230, and while the period is a short 6 seconds, that offshore wind will clean it up nicely. The swell direction is a good fit for what this sandbar likes. It’s not a big day, but after two weeks of nothing, it’s a welcome sight. The afternoon has a 6 ft swell from the SSW with a clean cross-off breeze, but it’s a bit more marginal.
The rest of the second week is still pretty average. The little bumps on the 13th, 14th, and 16th all have cross or cross-onshore winds, so the quality will be poor.
Bottom line: forget the next two weeks. Circle Monday, August 18th morning on your calendar. That’s your only real 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.
