The Lowdown
Right, look, I’m not gonna lie to you, things are flat out grim here at Road K. The forecast ain’t pretty, so I’m just gonna call it straight.
The whole 16-day window is a write-off. There’s no standout, no magic day, nothing even close to a decent paddle. We’ve got over two weeks of nothing but poor surf conditions with barely a ripple to get excited about. The best you’ll see is some tiny 2ft to 2ft slop, and even then, the wind is either rubbish or the swell is just too weak. It’s a long, dry stretch.
The first few days are a total bust. Saturday the 5th is flat with a weak 1ft SE swell and a 8-second period, just a sad little 23 (combined energy). The wind is offshore, but there’s no wave to ride. Sunday the 6th doesn’t get better; a 2ft E swell with a terrible 5-second period and 42 (combined energy) isn’t going to get you out of bed. The water temp is sitting at 71°, which is about normal for this time of year, not that it matters when there’s no surf.
The entire period is just a string of poor surf with scores of zero. We see a bit of a bump around Wednesday the 9th with a 3ft SW swell, but the wind is a messy cross-onshore, making it choppy. The real kicker is that the swell period is only 4 seconds – that’s pure wind chop, no power. The energy stays low, mostly in the double digits, until we get a small spike on Thursday the 10th with 5ft SSW swell and 229 (combined energy), but the wind is cranking from the WNW at 22 mph, so it’s gonna be a mess.
Even the later days, like the 18th of September, when we get a bit more energy (238 combined energy from a 4ft ESE swell), the conditions are still "marginal" at best, and the wind is weak cross-onshore. It’s just not happening.
For a spot like Road K, a sandbar that’s usually very consistent, this is a proper blank run. It’s one of those times where the ocean just says "not today." You’d honestly have more fun on a kite with these winds, because for a paddle surfer, there’s nothing to chase. Forecasts can change, but right now, this is as bad as it gets.

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.
