The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for Road K.
To be straight with you, this is a tough stretch. We’re looking at a long, dry spell with pretty ordinary conditions. The first real shot at anything comes from Thursday, 30 July, but even then it’s a struggle. The water temp is sitting at 71°F, which is about average for the time of year, so nothing wild there.
The pattern is dominated by small, weak swells and messy winds. There’s a little blip on Monday, 3 August, where the swell bumps up to 4ft from the south, with a period of 7 seconds – short period, won’t have much shape. That afternoon the wind goes offshore from the north, which is a rare positive, but the combined energy is only moderate (186). It’s surfable, but nothing to write home about.
The rest of the 16 days is filled with cross-on winds, tiny wave heights, and scores that are basically zero. There are a few mornings with clean conditions, like Thursday, 6 August, and Friday, 14 August, but the swell is tiny – 1ft to 2ft. At that size, you’re barely floating. The combined energy on those days is weak (40 and 43).
The best on offer, if you can call it that, is that Monday, 3 August afternoon. The swell is 4ft from the south, with that clean offshore wind from the north. It’s the only time in the whole window where the wind is truly offshore. But again, the period is short, so expect bumpy, weak waves. It’s more of a hopeful paddle than a proper session.
There are no standouts. No big swells, no long-period groundswells. The wind is mostly wrong. For a beginner, the small stuff might be okay, but for anyone looking for a proper wave, this is a full two-week wait for very little reward. Honestly, if the wind keeps up like this, the setup might be more interesting for kite surfing than paddle surfing, especially on those days with stronger cross-onshore breezes.
Conditions are generally poor, so don’t get your hopes up. Forecasts can change, but as it stands, this is a blank run.
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.
