The Lowdown
Alright, let’s talk about Road K. Things are looking pretty quiet here for a while. The water is about 71°F, which is normal for this time of year, so no surprises there.
The first real chance to get wet is Sunday the 19th. The morning brings a clean 5ft swell from the SSW, period around 8 seconds, with moderate energy. It’s not a classic, but it’s clean with an offshore wind from the WNW. That’s your best bet for the whole stretch, but it’s still a marginal call, so keep your hopes in check.
Monday morning the 20th is glassy, with a 3ft S swell, period 8 seconds. It’s small and clean, but nothing special. The rest of the week is a mess of onshore winds, lumpy conditions, and poor surf. There’s a big spike on Wednesday the 22nd morning with an 8ft SSW swell, period 9 seconds, and a huge amount of energy, but the wind is a near gale from the SSW, blowing it out completely. That’s for experts only, and probably better for kites. The Thursday afternoon the 22nd cleans up a bit with a 6ft S swell and a cross-off wind, but it’s still just marginal.
The second week is a slow grind. The swell stays small, mostly under 4ft, and the winds are all over the place. There are a few clean windows like Thursday morning the 30th with a 2ft swell and a light offshore from the NNW, and Friday morning the 31st with a 3ft swell and a light cross-off from the north. Both are clean but tiny, with weak energy. If you’re keen for a paddle, those are your moments, but it won’t be memorable.
For a stand-out, the Sunday morning the 19th is the only real highlight. It’s the only time the swell size and wind line up for something slightly better than ordinary. Crowds are often a factor here, so expect company if you go.

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.
