The Lowdown

Alright, let’s get into it. Rusty here.

First up, we’re looking at Ranches, and I gotta be straight with you – the next few days are a bit of a write-off. There’s just no energy in the water for a while. The first real chance of anything rideable won’t show up until Sunday, August 2nd. That’s a solid gap of a few days with nothing to recommend.

Now, for that Sunday (August 2nd), we’ve got a pulse of swell coming in. It’s a NE swell, hitting around 5 ft, with a period of 7 seconds – so it’s a short-period wind swell, not a groundswell, but it’s got some moderate energy behind it (310). The wind is offshore and clean, a steady 15 mph from the ENE. That will keep the surface tidy. The water is 80°F, which is about normal for this time of year.

The standout of the whole 16-day window, without a doubt, is Wednesday, August 12th in the morning. That’s a week and a half away, so it’s a long-range call, but it looks promising. We’ll have a 3 ft swell from the W with a long period of 13 seconds. That’s proper groundswell, and the energy is solid (320). The wind is glassy – dead calm, NNE at 3 mph – which means it’ll be absolutely clean. For a reef break like Ranches, that long-period W swell is a dream setup. It’s a fairly consistent spot, but crowds are possible, so get in early.

The other notable day is Monday, August 10th in the morning. Another W swell, this time 2 ft at 14 seconds with offshore winds (NE at 9 mph). That’s another long-period groundswell with good energy (250). It’s a solid option, but the 12th is the real prize.

For the rest of the second week, there are a few other mornings with small, clean surf – like August 9th and August 11th – but nothing that matches the quality of that 12th. The waves will be small, between 2 ft and 3 ft, but the wind is often offshore or glassy, so it’s worth a paddle if you’re desperate.

One thing to note: Ranches is a reef break, and it’s rated for advanced surfers. The swells here are mostly small, so it’s not a beginner’s playground. And with that long-period swell on the 12th, it’ll be lining up nicely, but the gaps between sets will be longer – that’s just the nature of groundswell.

Rusty out.

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.
