What’s up crew, Rusty checking in. Let’s break down the next couple of weeks at Ranches.
Water temp is a pleasant 80°, which is dead on average for July. No worries there.
The start of the run is a bit average. We’ve got swell running from the NE, up to about 5ft on Monday, but with a short period of 7-8 seconds, the waves are a bit weak and crumbly. The wind is offshore but strong, blowing 19 mph, which will kick up a bit of chop. The combined energy reads moderate (258). It’s surfable, just not great. This kind of lukewarm, short-period grind carries through to Thursday morning.
The real standout comes on Sunday July 12th. The morning is looking prime. We’ve got a long-period groundswell from the SW at 16 seconds – that’s proper energy. The wave height is only 3ft, but the combined energy is a strong 516, so it’s going to pack a punch. The wind is a clean offshore from the NE at 12 mph. This is the pick of the lot. The afternoon gets a bit messy as the wind shifts cross-off, so get your session in early.
That sets up a nice little run. From Monday the 13th through Wednesday the 15th, we get consistent long-period WNW to W swells (16-18 seconds). Wave heights are smaller, around 3ft to 3ft, but the combined energy is solid (338 to 480), so there’s plenty of push. The reef will be handling these perfectly. The wind is offshore, light to moderate. This is a great stretch of clean, punchy waves. Just remember the sets will be more spaced out with that long period.
After Wednesday the 15th, it all fizzles. Swell drops off, winds turn cross-onshore, and the energy goes weak. By the weekend of the 19th, we’re looking at tiny waves under 2ft and energy in the tank (30 or less). Not much to do.
So lock in the morning of Sunday the 12th as the standout. The following few days up to the 15th are still very good, just smaller. After that, it’s the waiting game.
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.
