The Lowdown
Alright, this is Rusty, and I’m looking at the forecast for the next couple of weeks down at Road K. Gotta be straight with you – it’s going to be a grind. The next week and a half is mostly a write-off with some small windows of hope.
The first glimmer of something decent doesn’t show up until Monday morning, July 20th. We’re looking at a tiny 3ft swell from the S, but the wind is absolutely glassy – zero breeze. That’ll clean things right up, but the waves are going to be small and weak, with a combined energy of only 110 (weak). The period is a short 8 seconds, so it’s not going to have much punch. It’s surfable, but it’s a real knee-high dribbler for the absolute beginners out there.
The next real standout, and the best of the run, shapes up for Thursday morning, July 23rd. The swell jumps up to a solid 6ft from the S, with a combined energy of 533 (strong wave energy) and a period of 9 seconds. The wind is a gentle cross-offshore breeze from the NNE, which is going to keep the faces clean. The forecast says “expect very good surf conditions,” and I’m feeling it. This is a proper head-high wave, but at 6ft, it’s going to be a bit much for the beginners. This is the one to circle on your calendar.
After that, Thursday afternoon sees the swell drop to 5ft, still from the S, but the wind goes light cross-onshore, so it won’t be as clean.
Then the surf drops off again. We get a few small, average days from Friday the 24th through the middle of the following week. The energy is weak, and the wind is mostly onshore or cross-shore, so it’s going to be lumpy and choppy.
The second week finally shows a pulse building again. Thursday afternoon, July 30th, we get a 5ft E swell with a clean offshore breeze from the N. The combined energy is 205 (moderate), and it’s a 7-second period. That’s a promising little window, but it’s a long way off, so keep an eye on it. Friday morning, July 31st, holds similar 5ft E swell with a clean cross-offshore breeze. That could be a nice end to the month.
Honestly, for the next 16 days, the only real standout is Thursday morning, July 23rd. The rest is a lot of small, weak, or wind-affected surf. The water temp is about 73°F, which is normal for this time of year, so at least you won’t need a thick wetsuit for those small sessions.
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.
