The Lowdown

Alright, let me level with you. The next couple of weeks are looking pretty grim for a proper paddle. The swell is small, the winds are mostly messy, and it’s going to take a while before we see anything worth getting excited about. We’re looking at a real dry spell for most of the first week, with barely a ripple on offer.

Right off the bat, for the 15th and 16th, we’ve got next to nothing. We’re talking ankle-biters, maybe 0.3ft to 1ft at Road K (Road-K), with the wind all over the shop. It’s going to be a frustrating wait, and there’s a good five or six days where I wouldn’t even bother waxing up.

Things get a tiny bit more interesting on Monday the 17th, with the swell pushing up to 6ft, but the wind is howling cross-shore and the conditions are just going to be a mess. It’s a short-period, wind-driven thing, so it’s not going to have any punch. By Tuesday morning, it drops to 4ft and the wind turns cross-offshore which cleans it up a touch, but it’s still just ordinary. The energy is weak to moderate, we're looking at 165 for the combined energy. Nothing to write home about.

The rest of that week is just more of the same – small, weak, and onshore. We're talking 1ft to 3ft with the wind constantly messing up the surface. Remember, that water’s running about 2° warmer than normal, which is pretty noticeable, but it’s not making the surf any better.

Now, there is a glimmer of hope. It’s a long way out, but check this out. On the 23rd of August, there’s a brief moment early in the morning where the wind goes glassy and we get a pulse of long-period swell – 12 seconds – coming from the southeast. The swell is only 1ft, but with that period and clean conditions, it might just be a fun little wave for a short while. But it’s a tease, because it falls apart by the afternoon.

The swell fades right out again until the 25th, where we get some more energy (up to 5ft) but it’s cross-shore and messy. Then a long-period groundswell is due in around the 26th and 27th. The 27th looks like the real standout in this otherwise bleak forecast. On the morning of Thursday, the 27th of August, we’re looking at 3ft of southeast swell with a period of 12 seconds. The wind is forecast to be glassy, which is a huge plus. The combined energy is a solid 214, which is a step up from what we’ve seen. Road K likes the SSE direction, so this is right in its wheelhouse. This is the one to wait for. It’s a week and a half away, so treat it as promising, not guaranteed.

After that, it looks like it’s going to get messy again with a strong cross-onshore wind building in over the weekend. There’s nothing else that gets close to that 27th.

So, there you have it. A whole lot of waiting for one potential glassy morning. If you’re desperate, the 23rd might be worth a paddle, but the 27th is the one I’d circle on the calendar. Hang in there.

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.
