The Lowdown
Alright, Rusty here. Let’s talk Ranches, a solid reef break for the advanced crew. The forecast opens with a real gem on Monday 13th July afternoon – clear skies, a steady NE offshore breeze at 15 mph, and a clean 3 ft swell grinding in from the southwest. That swell’s got some serious legs with a 15-second period, packing a strong 501 units of combined energy. Water temp is sitting right where it should be at 79°F, about average for this time of year – no surprises there. This is easily the pick of the entire outlook: clean, glassy, and punchy. Crowds can show up sometimes, but for a reef this well-shaped, it’s worth the company.
Tuesday 14th holds up nicely too – both morning and afternoon see a similar offshore flow, with the swell dropping a tad to 2 ft but still a long 16-second period. Energy stays solid around 295–353. Good quality, just a notch below Monday’s peak.
Wednesday 15th afternoon turns glassy with a light SW wind and 3 ft swell from the west, 15-second period, energy at 355. Early morning that day is a bit iffy with rain and light onshore breeze, so aim for the afternoon window.
Thursday 16th delivers another glassy day – morning calm, afternoon light NNW breeze, 2 ft swell from the west, 14-second period, energy in the 260s. Clean and workable.
Then it starts to fade. From Friday 17th through the weekend and into the following week, the swell shrinks and the wind swings more easterly, often cross-off or even cross-off with fresh breezes. The energy drops into the low 100s or even double digits by Monday 20th and Tuesday 21st. There’s a long stretch from around the 17th to the 22nd where only small, short-period NE windswell is on offer – period around 6–7 seconds – and the quality slips to ordinary or poor. Not much to get excited about.
A brief flicker on Wednesday 22nd morning: glassy conditions with a 2 ft, 16-second long-period pulse from the southwest, energy 161 – but it’s small and inconsistent. Worth a look if you’re desperate, but not a standout.
After that, it’s mostly poor through to the end of the 16-day window. A bit more swell shows up around July 27th–28th (4–5 ft from the north-northeast, short to moderate 8–9 seconds), but the wind turns cross-onshore, making it messy. For a reef break like Ranches, that’s not going to deliver clean lines. The best is definitely behind you in the first four days.
So if I’m calling it: Monday 13th July afternoon is your winner. Point the board that way, hope the crowds play nice, and enjoy the rare combo of offshore wind and long-period groundswell.
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.
