The Lowdown

Alright, mate, Rusty here. Let’s have a look at what’s coming up for Road K. We’ve got a bit of a slow start, but there’s some serious potential waiting for us in the second week if you’ve got the patience.

Right now, it’s a bit of a write-off. Wednesday the 22nd of July is a no-go with a messy cross-shore wind and a lumpy 7ft south swell. The energy is moderate (579), but the conditions are just poor. That carries on through the end of July and into the start of August. There’s a brief moment on Thursday morning the 30th where the wind goes offshore from the NNW, but the swell is only 3ft and the energy is low (142) – it’s surfable, but nothing to write home about. The crowds are often here, so don’t expect a secret session.

Then we get a gap. Honestly, from the 22nd of July right through to the 2nd of August, it’s not really worth paddling out. Choppy, onshore, and small. You’ll be better off checking the kites because the wind is strong and the surf is poor.

Now, here’s where it gets interesting. Monday morning the 3rd of August. Glassy conditions, a clean 6ft swell from the SSW, and the energy is strong (416). The wind is dead calm – glassy – and that’s a major positive. The wave period is 8 seconds, so it’s a short-period wind swell, but with that clean surface, it’ll be fun. Still manageable for a confident beginner, but it’s pushing the limit at nearly 7ft.

But the real standout is Wednesday the 5th of August. This is for the experienced crew only. The morning session sees a massive 13ft south swell, period a very long 12 seconds, and the energy is through the roof (4693). The wind is offshore from the NNW, clean. That’s a serious groundswell. The break is a sandbar, so with that long period, it might be a bit straight, but for the experts, it’s a proper session. The afternoon drops to 10ft, still windy offshore, and still excellent for experienced surfers. For the rest of us, it’s a spectator day.

Thursday the 6th of August settles back down to a clean 6ft with light offshore winds, a nice way to finish the run.

So, to sum it up: the first week and a half is a write-off. The best on offer is Monday the 3rd of August for a clean, glassy session, and Wednesday the 5th of August for the big-wave crew. Don’t get too excited about the long-range stuff – it’s promising but not locked in yet.

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.
