The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks.
Straight up, it’s a pretty grim run for the Ranches. We’re looking at a solid week of nothing really worth paddling out for. The first proper surfable day doesn’t even show up until Thursday the 30th, and even then it’s a bit of a tease. The water’s sittin’ at a warm 80°, which is bang on average for this time of year, so no surprises there.
The first half of the run is a write-off. Tuesday the 28th and Wednesday the 29th are all about messy, short-period windswell and cross-offshore breezes that just aren’t giving us any shape. You’d be fightin’ a losing battle.
Thursday the 30th is the first day you might want to look at. The morning brings a tiny 2ft swell from the southwest, but here’s the kicker – that swell is packing a 18-second period. That’s proper groundswell energy, and the combined energy hits 233 (moderate). It’s cross-on, so it’s gonna be a bit bumpy, but the potential is there for a clean, long wall if you can find the right bank. The afternoon cleans up a bit, but the swell drops right off.
Friday the 31st and Saturday the 1st are dead. Tiny, onshore junk. Forget it.
Sunday the 2nd of August is the best of a bad bunch. Morning brings a 4ft swell from the northeast with a 8-second period, and the offshore wind is moderate but clean. Combined energy is 195 (moderate). It’s not gonna be a world-beater, but it’s surfable. The offshore flow will keep the faces tidy, but it’s a little short-period, so expect some lumpy, sectiony waves. Not a standout, just the least bad option.
We then hit another dead zone from Monday the 3rd through to Thursday the 7th. A few tiny pulses here and there, but nothing that’s worth a drive.
Finally, Saturday the 8th of August is our one true standout. The morning brings a 2ft swell from the west with a 12-second period, which is long-period groundswell. The combined energy is 212 (moderate). The real story is the wind – a gentle offshore from the east-northeast. That’s gonna have the place glassy and clean. The swell is small, but with that long period and offshore breeze, the Ranches reef will be working. It’s a reef break, so it’s best for advanced surfers, and it’s fairly consistent. The crowd can be here sometimes, but on a day like this, with this small size, it’ll be quiet. The swell direction (W) is northwest, which is the optimum for this break. Don’t expect big waves, but expect clean, rideable lines.
After that, the run fades out. Sunday the 9th has some glassy conditions, but the swell is tiny and short-period. The final week is a write-off with onshore winds and no real energy.
Overall, this is a lean period. The only real standout is the morning of Saturday the 8th of August. If you’re desperate, Sunday the 2nd is the other option. Otherwise, save your energy.
Rusty.

Information about the Ranches Surf forecast
The above surf forecast table for Ranches provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ranches can be found by selecting the local surf guide option on the grey menu. Our Ranches 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 (Ranches) 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 Ranches 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.
Ranches is 22 km (14 miles) from Wahiawa. If you plan a vacation in Oahu, look for hotels and other accommodation in Wahiawa. Wahiawa has rooms for a wide range of budgets as well as car hire and transport links.
