The Lowdown
Alright, surf outlook for Road K (sandbar) over the next 16 days. I've been looking at the numbers, and it's a bit of a mixed bag, with more low points than high, but there are a couple of moments that might just deliver.
We kick off on Tuesday, July 14th with nothing to write home about. The swell is weak at 3ft from the SW, but that 19 mph cross-shore wind from the WSW is going to chop things up badly. The combined wave energy is a paltry 56, and honestly, the conditions are a write-off. Tuesday afternoon is no better—25 mph winds and messy surf.
Wednesday the 15th looks cleaner with a moderate breeze, but the swell is still short-period junk at 4ft. It's surfable, but nothing to get excited about.
Then we get a tiny window. Thursday morning the 16th: we get 3 mph winds from the WNW, turning it glassy. The swell drops to 2ft from the SSW, with a combined energy of just 55. It’s small, but it’s clean. For a beginner or someone with a log, this could be a fun, mellow session without any crowd drama—though it's sandbar, so expect it to be fickle.
Friday the 17th through Saturday the 18th is a flat and blown-out mess. Drops to 2ft or less, and onshore winds ruin any chance. Honestly, it’s more of a kite-surfing setup if anything.
Sunday the 19th sees a bump in swell, hitting 5ft in the morning and 7ft in the afternoon. But with 19 mph cross-offshore winds, it’s still a bit lumpy. The combined energy climbs to 204 and then 401, which shows there’s some juice. This size is borderline for beginners; at 7ft, you’d want to be an experienced surfer.
Now, here’s the standout. Monday the 20th looks promising. We get a 5ft swell from the south with a period of 9 seconds—a proper groundswell. With 9 mph offshore winds from the NNW, conditions will be clean and glassy. The combined energy hits 313. This is the best on offer in the whole forecast. The wind is offshore, the swell has some shape, and it’s the kind of day you’d set an alarm for.
After that, the window slams shut again. Tuesday the 21st has a fading 3ft swell with cross-offshore winds, but it’s ordinary at best. Then from Wednesday the 22nd through to Thursday the 23rd, onshore winds and rain make it a write-off, even though the swell picks up to 6ft and 7ft, it’s messy.
Friday the 24th and Saturday the 25th offer a glimmer with 4ft to 6ft swells, but the wind is cross-onshore, making it choppy. There’s a risk of thunderstorms. The combined energy is moderate (185-337), but the quality isn’t there.
The last few days, Sunday the 28th through Wednesday the 29th, are a write-off: strong onshore winds, rain, and lumpy conditions. The swell is there (3ft to 5ft), but you’d be fighting the wind and chop.
Verdict: The only real standout is Monday the 20th morning at Road K. The south swell (5ft, 9s) with offshore wind gives you the best chance for a clean, punchy session. For beginners, the glassy morning on Thursday the 16th (2ft) is a safe bet if you just want to get wet. Otherwise, it’s a long stretch of washouts. Forecasts can change, but as it stands, pick your windows carefully.

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.
