The Lowdown

Alright folks, it’s Rusty here. Let’s have a look at what’s coming up for Road K over the next couple of weeks. I’ve got to be straight with you right from the start – this is a bleak run for the waves. The whole 16-day window is a struggle, and there’s not a single day I’d call a proper standout. If you’re desperate for a paddle, you’ll find some windows, but you’ll be working for it.

The pattern is mostly small, weak, and messy. We’ve got a long stretch of poor conditions right through the end of July. The first real chance of anything comes on Thursday the 23rd, but even then it’s just a marginal call. The water temp is sitting at 73°, which is about 2° warmer than the average for this time of year, so nothing too unusual there.

Let’s walk through it. From the 18th through the 22nd, it’s a write-off. Small, choppy, cross-onshore winds, and periods around 4 to 7 seconds – that’s windswell junk. The combined swell energy is well under 100, basically weak and wobbly. On the 22nd, the swell bumps up to 8 ft to 8 ft, and the energy jumps to 879-996, but it’s coming in with a gusty cross-on wind, and the period is only 9 seconds. That’s not clean, and for a sandbar setup, it’ll be a washing machine. That’s expert-only territory if you’re keen, but honestly, it looks more interesting for kite surfing than paddle surfing.

Thursday the 23rd morning is your best bet in the whole outlook. The swell is 5 ft from the S with an 8-second period, and we get a clean offshore breeze from the WNW. The energy is moderate (351). It’s still a marginal forecast, but it’s the cleanest you’ll see. The swell is a bit too big for beginners, but for the experienced crew, that morning session might be worth a look. The afternoon gets messy again.

After that, it’s back to small, ordinary conditions. The 24th has a clean morning with 3 ft swell, but it’s weak. The 25th sees a glassy morning with 3 ft swell from the SE, but again, the energy is low (110). It’s surfable, but nothing to get excited about. The rest of the month and into the start of August is a mix of small swell, cross-shore winds, and chop. The 1st of August picks up a bit to 5-5 ft, but the wind is cross-on and the period is a short 7 seconds. The 2nd of August has a 7 ft swell, but it’s still short period and cross-shore, so it’s going to be lumpy and difficult.

The bottom line: there’s one marginal morning on the 23rd, and that’s about it. The rest is a long, dry gap with nothing to recommend. For a spot that’s usually very consistent, this is a poor stretch. Forecasts can change, but right now, I’d keep the board in the car and your expectations low.

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.
