The Lowdown

Alright folks, Rusty here. Let’s get into the outlook for the next couple of weeks.

First up, we’re looking at Ranches, a reef break that needs the right direction to light up, and it’s been a bit of a waiting game. The water temp is sitting at 80°, which is bang on average for this time of year, so no surprises there.

The first few days are a write-off. Sunday the 26th and Monday the 27th are just not worth paddling out for. The swell is small and weak, with combined energy barely cracking 191 (moderate at best), and the period is a short 8 seconds. The wind is offshore, but it’s too strong, and the waves are just ordinary. The next few days through to the end of the month are a waste of time, with poor conditions and tiny surf.

We hit a bit of a gap with no real recommendations, but things start to look up by Wednesday the 29th. That morning is the standout. The swell is 5ft from the NE, with a period of 11 seconds, giving it some real push. The combined energy is a solid 570 (moderate-strong), and we have a gentle breeze from the north, keeping it clean. This is the best on offer for the whole outlook. The waves will be well-shaped and powerful, perfect for a reef.

Thursday the 30th drops right off, with the swell fading and the wind turning onshore. Friday the 31st through to Monday the 3rd of August is a mix of tiny, weak swell and strong offshore winds, making for nothing but blown-out, ordinary conditions. The combined energy is mostly in the low double digits to low 200s, which is weak to moderate.

There’s a notable quiet spell from Tuesday the 4th through to Friday the 7th. The swell is flat or super small, and while there are some glassy moments, there’s just no wave energy to work with.

Then the last few days of the forecast show a promising change. Both Sunday the 9th and Monday the 10th of August have a long-period groundswell from the west, with periods of 16 seconds. The energy is building, with a combined energy of 215 on Sunday morning and 380 on Monday morning. The swell is small, around 2ft to 3ft, but with that long period, it’ll be clean and lined up. The wind is offshore and light to moderate on Sunday, making for clean conditions. Remember, this long period (over 15 seconds) is a proper groundswell and will work best at this reef, but it can be a bit tricky at beach breaks. This is a promising, but less certain, long-range option.

So, to wrap it up: Wednesday the 29th of July morning is the true winner here. If you can get out, that’s your session. The long-range stuff on the 9th and 10th of August is worth watching, but we’ll see how it firms up.

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.
