The Lowdown

Alright, Rusty here, checking in with a look at what’s on the cards for Ranches.

Right off the bat, I gotta be straight with ya – the next week and a half is a real mixed bag, with more time spent staring at flat or messy water than actually surfing. We've got a long, frustrating gap here. From now, it’s pretty quiet until Monday the 7th of September. That’s a solid few days of nothing worth getting wet for.

So, the first real glimmer of hope shows up on Monday the 7th. The swell kicks up to a solid 7 ft out of the southwest, with a long-period 14 seconds – that's proper groundswell energy, and the combined energy is a hefty 1669. It’s still a bit on the bigger, more powerful side, so this is one for the experienced crew only, as it'll be too much for most. The wind is coming from the ESE, so it’s clean, but it's cross-offshore. This continues into the afternoon with the swell pushing 8 ft and energy hitting 2391. The water temp is about 81°F, which is pretty much spot on for the time of year, so no surprises there.

Now, the real standout, the one that gets my heart pumping a little, is expected on Saturday the 12th of September. That afternoon, we see a long period 16-second swell, but only 2 ft. The real story here is the direction – it's out of the southwest, which is the optimum direction for this spot. The combined energy is a moderate 206, and with light NNE winds, it'll be clean. This is the kind of glassy, lined-up reef wave that makes it all worth it. It’s not a big day, but the quality should be there for those who know the lineup.

Another one to keep an eye on, though it’s way out there, is Monday the 14th of September morning. We’ve got a very long period 22-second groundswell, coming from the southwest. The swell height is only 2 ft, but with that kind of period and energy of 343, it could push in some sneaky sets. The wind is offshore from the NE, which is a beautiful thing for a reef like this. It’s a long-range call, so don’t book the week off work yet, but it has potential.

The second week is pretty slim pickings otherwise – mostly small, short-period swells in the 3 ft to 3 ft range with ENE winds, making for ordinary conditions. Nothing to write home about. A few glassy mornings pop up, but with no real push behind them.

So, to wrap it up, your best bet is the afternoon of Saturday the 12th for that clean, optimum-direction long-period swell, with Monday the 7th as the bigger, more powerful option for the experienced surfers only. The rest of the run… well, it’s a good time to clean your wetsuit.

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.
