The Lowdown

Alright, Rusty here. Let’s talk about what’s cooking at Road K.

To be brutally honest, the next week and a half is looking pretty flat and junky for the most part. We’ve got a real dry spell on our hands. The surf is small, the wind is mostly onshore or cross-on, and the periods are short – not much to get excited about. There’s a long gap of just poor conditions from Saturday the 25th of July all the way through to the end of the month. The water temp is sitting at 71°, which is about normal for this time of year, so at least you won’t need a thick wetsuit.

Now, if you’re patient, there is a little window that shows some promise. The standout in this whole 16-day forecast is the morning of Monday the 3rd of August. That’s the one to circle. We’ve got a 4ft swell coming from the SSE with a clean, cross-off wind from the NNE. The combined energy of all swells directed here is moderate at 317, and the conditions are forecast to be clean with good surf. It’s not a monster, but after all that nothing, it’s the best on offer. Keep in mind that Road K is a sandbar, and it’s very consistent, so even on a small day it can have a shape. The crowd situation is often busy, so expect some company.

Before that, there’s a brief flash on the 29th of July. Wednesday afternoon shows a 5ft swell from the south with a fresh offshore wind from the north, which is a major positive. The combined energy is strong at 613. But it’s flagged as a marginal forecast, so it’s a gamble. Still, if you’re desperate, that might be the only other time with a clean look.

Everything else is either too small, too choppy, or just plain poor. A few days in early August have some energy, like the 4ft on the 3rd, but the winds are generally onshore and messy. The setup at Road K is exposed, so it takes the brunt of any bad wind. If the wind stays strong and the surf quality stays poor, this spot might actually be more interesting for the kite-foilers than for paddle surfers.

Hang in there, the 3rd of August is the one. After that, it fades back into small, weak junk.

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.
