Alright folks, Rusty here. Let's get stuck into what's coming up for Ranches over the next couple of weeks.
Right off the bat, we've got a bit of a slow start today, Friday the 10th. The swell is small at 4 ft from the NE with a short, weak period of 6 seconds and combined energy is only 100. It's rideable, but it's pretty ordinary. We need to wait for the weekend.
The real action kicks off on Saturday morning, the 11th of July. We'll see a bump in size to 4 ft from the NE, with a period of 7 seconds and a jump in energy to 212. The wind is a clean offshore from the ENE at 12 mph. This is solid, clean, and fun – a definite standout for the period. The water temp is sitting at 79°, which is bang on average for this time of year, so no surprises there.
Sunday the 12th is where things get interesting. The swell drops to 3 ft, but it's a long-period groundswell from the SW, a solid 16 seconds. The energy is pumping hard at 608. The wind stays clean offshore from the ENE. This is a classic Ranches setup – the long period will groom the reef perfectly, offering proper shape and power. Another standout morning, but keep in mind that long period is better for a reef like this than a beach break.
Monday the 13th holds on with similar conditions – 3 ft SW swell at 15 seconds (energy 483) in the morning, and a shorter 4 ft NE swell in the afternoon. Winds are offshore all day. Consistent, clean, and good.
Through the middle of the week from Tuesday the 14th to Thursday the 16th, we get a smaller, clean run of surf. Swell drops to 2 ft to 3 ft from the W, with periods around 14 to 16 seconds. Winds are light offshore or cross-off. It's not huge, but it's clean and surfable. The energy is moderate, ranging from 273 to 386.
Then we hit a dry spell. From Friday the 17th through to the end of the run, conditions get real small and weak. The swell drops to 1 ft to 4 ft, but it’s all short-period, weak NE windswell with energy dropping below 100 most days. There's a couple of days there with poor conditions and strong winds, especially the 20th and 24th where it's looking messy.
To wrap it up, your best bet is this weekend. Saturday the 11th and Sunday the 12th of July are the true standouts. Clean, offshore winds with decent energy. After that, it's a waiting game for the next proper pulse.
Rusty, signing off.

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.
