Alright, let me tell you what’s coming up for Ranches over the next couple of weeks. This reef break is exposed to the swell, and it likes swell from the NW best, so we need the right stuff to line up.

First up, the water temp is sitting at about 80°, which is pretty much bang on average for this time of year – nothing weird going on there.

We kick off on Tuesday the 7th of July with some messy, short-period 5ft NE windswell. The energy is moderate (247), but the period is a short, weak 8 seconds, so the waves will be gutless and bumpy. The offshore wind is solid from the NE, but the quality just isn’t there for a good paddle. Honestly, the first few days look ordinary. Wednesday and Thursday the 8th and 9th bring similar small, short-period swell around 4ft, with clean offshore winds, but the wave shapes will be unremarkable. It’s surfable, but nothing to write home about. That run of "just okay" waves continues into the end of the first week.

The first real standout comes in on Sunday the 12th of July. The swell flips direction to a long-period SW groundswell, 3ft but with a juicy 16-second period. The energy jumps right up into the strong zone (584-646), and we’ve got clean offshore ENE winds. This is what Ranches is built for. The long period means better shaped waves, more energy in each wave, and longer lulls between sets – which makes paddling out easier. It’s a reef break, so that long period will wrap in nicely. This is the best stretch of the whole forecast. Monday the 13th is nearly as good, with 3ft of SW swell at 15 seconds and gentle offshore winds. This is where you want to be. Crowds are possible here sometimes, but with this quality locked in, expect some company.

We back off a little into the second week. From Tuesday the 14th, we’re looking at smaller 2ft west swells with long periods (15-17 seconds). The energy drops to moderate levels (300-315), but the winds stay offshore and clean. Waves will be cleaner and more organised than the windswell earlier, just smaller. It’s a good, chill mellow surf for those with a longboard.

Through the end of the second week, the swell gets inconsistent. Around Friday the 17th, a weak 4ft NE windswell pops up, but period is a short 7 seconds again, so quality is poor. Then we hit a flat, weak stretch from the 18th to 20th with tiny waves and very low energy (41-168). That’s a real lull. Finally, on Tuesday the 21st of July, we see a small 2ft SW groundswell with a 16-second period arrive, but energy is only moderate (224) and the afternoon turns poor. It’s a promise of something better, but it’s far off and uncertain.

So the clear winner: next weekend, Sunday the 12th and Monday the 13th of July. That’s the SW groundswell that’s got the power, the period, and the wind. Be there.

Stay stoked,
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.
