The Lowdown
Right, folks, Rusty here. Let’s have a look at what’s on offer for Road K over the next couple of weeks.
Straight up, I’m not gonna sugarcoat it. This is a tough run. The first decent surf we see doesn’t kick off until Thursday morning, July 23rd, and even then it’s nothing to write home about. We’re looking at a long stretch of pretty ordinary conditions for the most part.
We start off Thursday morning, July 23rd, at Road K. The swell is a small 4 ft coming from the south with a short 8-second period. The combined energy is moderate at 182. The wind is a light cross-offshore from the NNE, which is keeping things clean. The water temp is sitting at 70°, which is about 2° cooler than usual for this time of year, so pretty average. You’ll get a wave, but it’s hardly a standout.
The next few days are a write-off. Thursday afternoon sees a cross-on wind, and from Friday, July 24th, through to Monday, July 27th, the wind is either cross-shore or cross-onshore, with the swell dropping to as low as 1 ft. The energy is weak, with readings in the 50s and 60s. It’s just not worth paddling out for.
We get a bit of a bump on Tuesday, July 28th, with the swell jumping to 6 ft from the SSE, but the period is a dismal 6 seconds. The energy is moderate at 256, but the wind is cross-shore in the morning and cross-onshore in the afternoon. The conditions are marginal at best.
Wednesday, July 29th, brings a brief moment of hope. The wind swings offshore from the north in the morning, but it’s howling at 25 mph. That’s going to put a nasty chop on the surface and make it a real battle to paddle into anything. The afternoon is better with a gentler offshore from the NNW at 9 mph, and the 4 ft south swell looks clean. The energy is moderate at 194. It’s surfable, but nothing special.
From Thursday, July 30th, right through to the end of the forecast on Friday, August 7th, it’s a desert. The wind is almost always onshore or cross-onshore, the swell is inconsistent, and the energy is weak. The only real spike is on Monday, August 3rd, where the swell hits 7 ft from the SSE with a 10-second period and a strong energy of 772. But the wind is onshore from the SSE, so it’s going to be a messy, blown-out mess. Not one for the beginners, and honestly, not much fun for anyone else.
The best bet in this whole window is probably Wednesday afternoon, July 29th. The gentle offshore wind from the NNW will keep the 4 ft south swell clean. The energy is moderate, but the conditions are the most surfable we’ll see. It’s not a classic, but it’s the closest we get.
After that, the forecast is grim. There are gaps of several days with no real recommendations. The crowds at Road K can be a problem, so keep that in mind.
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.
