The Lowdown
Alright, Rusty here, let's talk about what's on the menu for Ranches. It’s a reef break that needs a solid NW swell to fire, and we’re looking at a bit of a slow cooker of a forecast over the next couple of weeks. The water temperature is sitting at 80°, which is pretty much bang on average for this time of year, so no surprises there.
The outlook gets going on Saturday, the 18th of July, but honestly, it’s a tough start. We’ve got a tiny 1 ft swell from the WNW with a long 13-second period, but that’s just not enough oomph to make this place sing. It’s surfable, sure, but you’ll be scratching for waves. That sets the tone for a pretty flat run. From Sunday the 19th right through to Thursday the 23rd, it’s mostly onshore junk or just flat spells with no waves showing up at all. There’s a brief flicker on Sunday afternoon with 3 ft from the NE, but the period is a short 6 seconds, which is just messy.
We finally get a bit of life back on Friday the 24th. The swell bumps up to 4 ft out of the NE, with a 7-second period. There’s still some moderate energy there (136), and the wind is holding offshore, so the surface will be clean. It’s not a standout, but it’s a step in the right direction.
Now, the real highlight falls on Saturday morning, the 25th of July. This is where you want to be in the water. We’re looking at 4 ft of NE swell, a bit more period at 8 seconds, and the wave energy is cranking up to 205. The wind is offshore and clean, which is a major positive for this exposed reef. It’s a solid, fun size for an advanced surfer, and with the offshore breeze, you’ll get some proper walls. Just know that crowds are sometimes an issue here, so get in early.
The Tuesday the 28th of July afternoon session also looks glassy with 3 ft from the NE, but it’s inconsistent so you might be doing a lot of waiting.
Looking further out, towards the end of the month, there’s another interesting pulse. On the 30th of July, Thursday morning, we get a tiny 2 ft swell from the SW with a very long 18-second period and the energy jumps to 211. For a reef break like this, that long period is a dream; it’ll offer up some deep, lined-up waves. But again, it’s small.
The final weekend (2nd of August) shows the best quality for the whole run. Sunday morning and afternoon both deliver 2 ft from the W with that lovely 13-second period. The combined energy is strong at 228 and 244, and with a moderate offshore breeze, this will be clean and fun. For a break that can be finicky, this is the most promising period in the second week.
So, if you’re keen, make a plan for Saturday morning the 25th of July at Ranches. Otherwise, the long-range Sunday the 2nd of August has the best quality on offer.
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.
