The Lowdown
Alright, let’s get this straight out of the gate: the next few days don’t have much to shout about. There’s a real lull through the end of July and into the start of August, with pretty much nothing rideable from Wednesday the 29th right through to Saturday the 1st. A lot of tiny, weak slop and flat spells in there, so save your wax.
Things start to perk up by Sunday the 2nd. That’s when a little pulse arrives. The water temp is sitting at about 80°, which is pretty average for this time of year.
Sunday morning the 2nd brings a NE swell around 4ft (moderate energy around 200) with a short, choppy period of 8 seconds. It’s not gonna blow your mind, but with clean offshore winds from the NE at 15 mph, it will be workable for the advanced crew at Ranches. The swell direction is coming from the NE, which aligns nicely with the optimum direction for this break. Crowds can be an issue here sometimes, so you might have to jostle for a few. That afternoon looks even better on the energy front (258) and stays clean.
Monday the 3rd sees the swell drop right back off again, and we go into another poor stretch through the middle of the week. There’s a tiny glassy moment early Tuesday but barely a ripple. Through to the 6th, don’t expect much.
Now, the standout window opens later. Saturday morning the 8th of August looks like the pick of the bunch for me. We’ve got a clean 2ft swell coming from the west with a decent 12-second period and moderate energy (210). The wind is light cross-off from the NE, so the surface should stay pretty tidy. Not big, but clean and lined up – a real gem for a relaxed session at Ranches.
Then Monday the 10th of August is another one to circle. The swell bumps up to a consistent 3ft from the NE with good energy (286) and a 9-second period. The wind goes glassy offshore in the morning from the ENE at just 3 mph. That is a recipe for some proper clean, friendly waves. It’s not big enough to scare anyone off, so intermediate surfers should feel right at home too.
The end of the run on Tuesday the 11th looks promising as well with some long-period energy from the west (13 seconds, 314 energy), but that’s a week and a half out, so keep an eye on it – promising but not locked in yet.
Honestly, it’s a slow start, but that second week has a couple of days that are worth waiting for. Keep the board handy.

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.
