The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid little window of surf coming up at Ranches, but it’s a bit of a slow burner. The first couple of days are pretty ordinary, with stuff under 3ft and not much energy behind it. The real action starts to kick off from Friday morning, 24 July, and into the weekend.
Wednesday morning, 22 July, has a weird little spike of a long-period 17-second swell from the SW, but it’s only 2ft. The energy is there (197 combined energy), and with clean offshore winds, it’ll be rideable, but it’s not going to have any punch. Best to wait it out.
The standout is Saturday afternoon, 25 July. That’s where we see the best combination of the whole forecast. Swell pushes up to 5ft from the NE, period a consistent 8 seconds, and the offshore wind is cranking from the ENE at 25 km/h. The combined energy jumps to 270 (moderate wave energy), and the conditions are clean. This is the pick of the lot. It’s going to be a bit too big for beginners, but for the advanced crew, that offshore wind on a reef setup like Ranches is going to be a treat. The optimum swell direction is NW, and we’re getting NE, but with that offshore wind and the quality of the reef, it’s still the best on offer. Crowds are possible, so get out there early.
Friday morning, 24 July, is also worth a mention. 4ft from the NE, 7-second period, and a solid 239 combined energy. The offshore wind is 20 km/h and clean. It’s a notch below the Saturday peak, but a solid session for sure.
After that, the surf drops off again. Sunday morning, 26 July, has 4ft but the wind goes cross-off, and the energy drops. There’s a long gap of small, poor-quality surf from Monday, 27 July, right through to the end of the first week of August. There’s a tiny glimmer on Wednesday morning, 5 August, with 3ft from the NE and a period of 11 seconds, giving a 169 combined energy, and the wind is light and clean. It’s surfable, but nothing to get excited about.
As for the water, it’s around average for the time of year, so no nasty surprises.
Rusty, signing off.

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.
