Table - best surf conditions forecast for Ranches over the next 16 days.
Alright, let’s look at Ranches. This is an advanced reef break, and the water temp is about 79°F – right where it should be for this time of year. The action starts Sunday afternoon and carries through the first few days, but don’t expect a big swell; it’s more of a steady, high-quality pulse.
Sunday afternoon (July 12th) kicks it off: some clouds, moderate NE offshore wind, and 3ft of swell from the SW with a very long 16-second period. Combined energy is moderate at 598. For a reef, that long period means the waves will be hollow and lined-up – proper groundswell. Paddling out will be easier between sets. It’s not big, but the quality is spot on.
Monday morning (July 13th) is similar: ENE offshore breeze, 3ft SW swell at 15 seconds, energy at 480. Still clean. Monday afternoon the wind swings NE and the swell turns to a NE windswell with a 7-second period – much less interesting. Stick to the mornings early on.
Tuesday morning (July 14th) is lighter: 2ft from the west, 16-second period, with a NNE cross-offshore breeze. Clean, but smaller. Tuesday afternoon the NE offshore picks up again, 2ft W swell at 16 seconds, energy climbing to 371 – another good window.
The real standout? Sunday afternoon and Monday morning. That long-period SW groundswell with offshore wind and moderate energy is the cleanest, best-shaped stretch. Crowds are *sometimes* a factor here, but with it being an advanced reef, you won’t see a circus.
Wednesday morning (July 15th) goes onshore with WSW wind – skip it. But Wednesday afternoon? Glassy. Dead calm. Still 3ft W swell at 15 seconds. That’s a sneaky good session for anyone who can wait.
Thursday and Friday (July 16th and 17th) stay clean with NE offshore or glassy conditions, swell around 2-2ft from the west at 14 seconds. Energy is in the 200-300 range – not pumping, but fun.
Then we hit a long dry spell. From Friday afternoon (July 17th) through the weekend and into the next week, the swell turns short-period NE windswell, mostly 6-7 seconds. Energy drops into the weak double-digits (48, 30, 73, etc.). A few windows pop up – like Sunday morning (July 19th) with 3ft NE and offshore wind, but at 7 seconds it’s choppy and ordinary. This stretch lasts from the afternoon of July 17th all the way to the morning of July 27th – nearly 10 days of mostly poor to ordinary surf.
Finally, on Monday morning, July 27th things look promising again. Glassy conditions, NNW light wind, 4ft NE swell with a 9-second period and energy at 244. That’s the first real energy bump in a while. Monday afternoon keeps building: 5ft NE swell, 9 seconds, energy at 320, with a cross-offshore breeze. This is the best of the entire second week – bigger, cleaner, and longer period than anything in the preceding days. It’s a long-range call, so not locked in, but it’s the one to circle on the calendar.
First half of the week is golden. After that, you’re waiting for that late July bump.
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.
