Alright folks, Rusty here. Let’s break down what’s in store at Ranches.

Water temp is sitting on about 80°, right where it should be for early July. The week kicks off with a bit of a slow start. Sunday the 5th of July has some clean waves, but the real goodness is a little further out.

Sunday afternoon gives us a clean offshore breeze from the ENE at 15 mph. Swell is a modest 4ft out of the NE, with a short period of 7 seconds. The combined swell energy is moderate at 202. It’s surfable and clean, but nothing to write home about.

Then Monday through Thursday we’re in a bit of a funk. Swell sits around 5ft to 5ft, still from the NE, period staying short at 7-8 seconds. Winds are offshore but stiffer, blowing 15-19 mph, keeping things clean but a bit rough. Combined energy ranges from 177 to 270, all moderate. Just ordinary.

Thursday afternoon picks up a little with a gentler 9-12 mph offshore breeze and 5ft NE swell, energy at 221. Conditions start to tidy up.

Friday and Saturday keep the same story: small NE swell at 3ft to 4ft, short period, clean offshore winds. Saturday afternoon has combined energy of 249 – moderate but workable. It’s okay, not pumping.

Now, here’s where it gets interesting. On Sunday the 12th of July, everything changes. The swell direction flips to the SW, and while the optimum for Ranches is NW, so it’s not a perfect match, the period jumps to a very long 16 seconds, and combined swell energy hits 570-594, which is strong. Swell height is only 3ft, but that long-period groundswell packs a punch. Winds are offshore from the NE at 12-15 mph, keeping it clean. This is your best window – a proper deep ocean groundswell with real shape. This is an advanced reef break, so that long period will give lined-up, powerful waves. Expect some company, as crowds are sometimes around.

Monday the 13th backs off, with a mix of cross-off winds and 2ft to 3ft swell. Tuesday the 14th shows another pulse of long-period groundswell: 2ft to 3ft from the W with 16 seconds. Combined energy is strong at 517 in the morning. Light, clean winds. Another solid day.

But the real sleeper? Wednesday the 15th of July morning. Glassy conditions – wind from the N at 3 mph, dead calm. Swell is 3ft from the W, period 15 seconds, combined energy at 393 (moderate). That morning will be as clean as it gets. Get out there if you can.

After that, it fades. Thursday the 16th still has some 2ft W groundswell, but the wind turns cross-off and energy drops. Friday and beyond are mostly tiny to flat, combined energy around 50-172, and by Monday the 20th there is no swell at all.

The standout: Sunday the 12th of July and Wednesday the 15th of July morning are the two clear winners. Sunday has the size and power, Wednesday has the glass.

For a reef break this exposed and advanced, anything over 5ft starts getting expert-only, but most of this run stays in the manageable zone. Beginners should watch the 5ft days on the 6th and 7th.

Go get some.

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.
