The Lowdown
Alright, Rusty here. Let's have a look at what the ocean’s got cookin’ for us.
Right off the bat, I gotta be straight with you—this stretch is a lean one. The first few days are just tiny, weak little waves, nothing to get excited about. We've got a 2ft swell from the west-northwest on Saturday the 22nd with a period around 10 seconds, and the energy is weak at best (51). The wind’s blowing offshore from the east-northeast, so the surface will be clean enough, but the waves are small and ordinary. That morning session might be a paddle and a tan, not much else.
Sunday the 23rd is more of the same story—small 2ft swell, though the energy does pick up a bit to a moderate 132 in the morning. The wind stays offshore, so it's clean, but we're still talking about very ordinary, knee-high dribblers. Monday the 24th is no different, just a little 1ft to 2ft wave with a gentle offshore breeze. Honestly, through the middle of the week, we hit a real flat patch with combined energy dropping to zero on Tuesday the 25th and Wednesday the 26th—just no swell to speak of.
It's not until Saturday the 29th afternoon that we see a tiny pulse, with a 4ft swell from the northeast, period a short 7 seconds, and energy climbing to 113. The wind is moderate offshore, so it’s rideable, but it’s still a far cry from good. Sunday the 30th afternoon brings a 5ft from the north-northeast with a decent kick in energy (318), but it’s gonna be a bit raw and the period is still short.
The only true standout in this whole 16-day window falls on Monday the 31st of August. The afternoon session shows a 4ft swell from the northeast, consistent enough, with moderate offshore wind. That’s the closest we get to "good" conditions—score a 2 out of 10 in the guidance, which is the best rating you’ll see in this entire run. The energy is a solid 250, and while the period is still a short 7 seconds, for this spot, it’s the pick of the litter. It’s a reef break, so that short period won’t help much for shape, but on a clean day with that size, it’s worth a look. Just be aware, this break (Ranches) is an advanced-level spot, so leave the foam boards at home.
After that, we fade back into weaker, smaller swells through the first week of September, with conditions turning poor. The 4th of September morning shows a 3ft northeast swell with light offshore wind and moderate energy, but it’s still not a standout.
The long-range stuff, like Sunday the 6th of September, shows a faint pulse returning, but don’t hold your breath.
Wind stays mostly offshore through the whole period, which is a blessing, but the swell just isn’t there for a proper session most days. If you’re a regular, you know this area can have blank runs, and this is one of them.
Stay patient, keep an eye on the sky, and don’t force it.
Signing off,
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.
