G’day folks, Rusty here. We’ve got a mixed bag coming up for Ranches over the next couple of weeks, but there’s a definite sweet spot to kick things off. The first few days are the clear winners, so make the most of ‘em.

Right out of the gate, we’re looking at Sunday the 12th of July as the standout. Ranches is a reef setup, exposed to the swell, and we’ve got a nice long-period groundswell rolling in from the SW. Swell height is sitting around 3 ft, with a period of 16 seconds – that’s proper groundswell energy, the kind that builds solid, well-shaped lines. The combined wave energy is a strong 586 on Sunday morning, bumping up to 620 in the arvo. On top of that, we’ve got a moderate ENE offshore wind all day at 12 mph. That means clean faces and some real quality waves. It’s advanced territory here, and it’s fairly consistent, so expect some good ones. The water temp is about average for this time of year, so nothing unusual there. Just be aware it can get a crowd sometimes.

Monday the 13th of July is still very good, but dials back a touch. Morning has gentle offshore breezes from the ENE at 9 mph with the swell still a clean 3 ft from the SW, though the period drops to 15 seconds. The energy is still solid at 480. Come afternoon, the swell shifts to a shorter-period NE windswell at 4 ft with only a 7-second period, so it’ll be a bit more crumbly and less powerful. Still fun, but the morning is the pick.

Tuesday the 14th of July sees the SW groundswell drop to 2-2 ft, but it’s still a long 16-second period. Morning has a light cross-offshore breeze from the NE at 9 mph, keeping things clean. Energy is moderate at 286-355. It’s surfable, but nothing special.

Wednesday the 15th of July is where we hit a wall. Onshore winds kick in from the W at 6 mph, with rain showers in the afternoon. The swell is still around 3 ft, but with that onshore wind, it’s messy. The morning is marginal, and the afternoon is poor. Best to give it a miss.

Thursday the 16th of July offers a little hope. Morning glass-off conditions with a light N wind at 3 mph and a 2 ft SW swell at 14 seconds. Energy is 256. That’s a clean window, and the cross-offshore breeze in the arvo keeps it tidy. It’s a decent session for a small-wave board.

From Friday the 17th of July through to the end of the first week and into the second, the swell drops off and the quality fades. We get some cleaner mornings with offshore winds, but the swell size drops under 3 ft, and the period mostly sits around 6 or 7 seconds – short-period stuff. Energy values drop into the low triple digits and then into double digits. There’s a solid gap of ordinary to poor conditions from the 18th right through to the 27th of July. Windy afternoons and weak swell dominate. The 22nd of July morning has glassy conditions with a 3 ft NE windswell, but it’s only got 6-second period and energy of 60 – weak and gutless. On the 27th of July, there’s a slight uptick to 3 ft from the NE, but again it’s short period and the energy is still low at 90.

So, in short: Sunday the 12th is your absolute best bet – don’t sleep on it. Monday morning is the runner-up. After that, it’s a long stretch of small, weak, or onshore conditions. Keep an eye on the long-range, but for now, get out early this weekend.

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.
