Table - best surf conditions forecast for Ranches over the next 16 days.
Alright folks, Rusty here. Let’s get into it for the next couple of weeks.
We’ve only got one spot in the frame this time: Ranches. It’s a reef break, so it needs a decent swell direction to really fire, and it's exposed to the open ocean. The water temp is sitting at 80°, which is about average for the time of year, so nothing to write home about there.
The first few days are pretty ordinary. Thursday afternoon, the 9th of July, you’ll find some small 4ft NE swell, but it’s short-period stuff at 7 seconds and the energy is weak (147). The wind is offshore, which is good, but the conditions are just "surfable" – not really worth paddling out for. Friday is much the same, with the swell dropping a touch and the energy falling off. It’s a bit of a waiting game.
Things start to pick up on Saturday morning, the 11th of July. The swell bumps up to 4ft from the NE, still short period, but the energy jumps to moderate (212). The wind stays offshore, and the forecast says "expect good surf conditions." It’s still not a standout, but it’s a step in the right direction.
Now, the real highlight comes on Sunday, the 12th of July. This is the one. We’ve got a long-period groundswell from the SW, 16 seconds, with a height of 3ft. The energy is strong (597) – that’s the kind of reading that gets your attention. The wind is offshore and gentle. For a reef break like Ranches, that long-period SW groundswell is absolutely perfect. It’ll be clean, well-shaped, and the sets will have real push. The Sunday morning window is the best on offer, and Monday morning the 13th is a very close second with similar conditions. That’s the standout window right there.
After that, the swell drops back. Tuesday and Wednesday are still okay, with some solid W groundswells (15-16 seconds) and moderate energy, but the size is down to 2-3ft. Wednesday morning the 15th is particularly nice with glassy conditions – that’s a sneaky good session if you’re free.
The second week gets a bit patchy. The consistent offshore winds are a plus, but the swell energy drops off a cliff. We get a few pulses of that long-period SW groundswell again around the 21st and 22nd of July, but the energy is weaker and the heights are tiny (2ft). Not really worth chasing. The last few days of the window are mostly poor, with strong winds and low energy, so the best bet is definitely the first weekend into the following Monday.
Crowds at Ranches can show up sometimes, so on those standout days, especially Sunday the 12th, expect a few other salty dogs in the lineup.
Stay sharp, and get it while it’s good.
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.
