The Lowdown

Alright, Rusty here, let's have a look at what Road K's got cookin'.

We're starting off on a bit of a flat spell. The first real pulse of energy we can talk about doesn't show up until Wednesday the 29th of July, but even then, it's not looking friendly. For the first few days, from Saturday the 25th right through to Tuesday the 28th, the swell is just too small and junky to bother with. We're looking at a solid gap of four days of no-go surf.

Then on Wednesday the 29th, we get a jump in size, but the wind is a bloody mess. Wednesday morning brings a 7 ft swell from the ESE but it's howling onshore, turning it into a washing machine. By the afternoon, the swell jumps to 8 ft (1011 combined energy), which is a serious step up, but it's still onshore and looking like a stormy mess – more for the kite crew than the paddle crew.

Now, Thursday the 30th of July is where it gets interesting. The wind finally swings offshore from the NNW, cleaning things right up. We get a 4 ft swell from the SSE, pushing in with a stacked 345 combined energy. The guidance says this spot loves swell from the SSE, so this is a match made in heaven. The period is only 8 seconds, so it's not a long-period groundswell, but the clean, offshore conditions will make these waves peel nicely for a beginner-friendly sandbar.

The real standout, the one I'd circle on the calendar, is Monday the 3rd of August. The morning has a 4 ft, 9-second S swell with 269 combined energy and light offshore winds from the NW. Then the afternoon goes glassy. Flat calm. A classic 4 ft S swell with a glassy surface. That is the session to wait for. Clean, fun-sized waves with decent shape for the sandbar. The water temp is about average for this time of year, so you won't need a steamer but a spring suit will do.

After that magic Monday, the week trails off. Tuesday the 4th is okay with a clean 3 ft, but nothing special. Wednesday and Thursday stay small, and we're back to a slow fade by the weekend of the 8th and 9th of August.

So really, the pick of the fortnight is that Monday the 3rd of August, with the glassy afternoon. Thursday the 30th of July is a solid second option for a clean, offshore morning. The rest is just waiting around.

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.
