The Lowdown

Alright, Rusty here. Let’s have a look at what’s cookin’ for Road K.

To be straight with you, the next couple of weeks are looking pretty flat. We’ve got a long stretch of poor surf, with only a few glimmers that might get you out of bed. The water temp is about what you’d expect for this time of year, nothing wild.

The first real chance of anything decent won’t come until Thursday the 30th of July. Thursday morning at Road K, we’ve got a small 3ft swell from the S, with a period of 8 seconds. The wind is light from the N, blowing cross-offshore, which will keep the surface clean. The combined energy is moderate (154). It’s surfable, but very ordinary. Not a standout, just a chance to get wet.

The next morning, Friday the 31st of July, is similar. Another 3ft swell from the SSE, still cross-off from the NNE, and the surface should be clean. Again, the energy is moderate (109), but it’s nothing to write home about. It’s a small, weak swell.

After that, the surf drops off again into the first week of August. We’re looking at a lot of days with poor surf and onshore winds picking up, making for messy conditions. The swell stays small, mostly under 3ft, and the period is short. It’s a real quiet spell.

Now, the one day that stands out – and it’s a long way off, so keep your expectations in check – is Friday the 7th of August. That morning, the forecast shows a solid 5ft swell from the S, with a period of 7 seconds. The wind is light from the NW, blowing offshore, which is a major positive. The combined energy jumps to 241, which is a noticeable bump in power. The forecast says “expect good surf conditions.” This is the best on offer across the whole 16-day window. For a sandbar break like Road K, that 5ft is solid, and with offshore winds, it could be worth the wait. The short period means it’ll be a bit weaker and more straightforward, but still fun. The water is glassy. This is the one to circle on your calendar, but remember, it’s a week and a half away, so don’t bank on it just yet.

The following morning, Saturday the 8th of August, is a letdown after that. The swell drops back to 3ft, and the wind swings back to a cross-off, but it’s just not the same.

So, overall, you’ve got one potential standout on Friday the 7th of August. The rest of the time, it’s lean pickings. The wait will be worth it if that forecast holds.

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.
