The Lowdown
Alright, this is Rusty. Let's talk about what's on the menu for the next couple of weeks.
Honestly, the next few days are a bit of a write-off. We've got virtually no swell to speak of and the conditions are just ordinary. You're looking at a real flat spell until Friday the 24th, when a tiny 4 ft swell from the NE shows up with a short period of 7 seconds, but it’s still very average. Saturday the 25th offers a small bump to 4 ft, also from the NE, with a period of 8 seconds, and by the afternoon the forecast looks a little more promising. The water here is sitting at a pretty normal 80° for this time of year, so no surprises there.
The standout window is shaping up to be around Thursday the 5th of August and into Friday the 7th. Let’s get into it.
Ranches (reef)
This is where the real hope lies. On the morning of Thursday the 6th, we’ve got a clean 3 ft NE swell with a 10-second period, and the wind is a gentle offshore breeze. The combined energy is moderate at 216. It’s not huge, but it’s clean and lined up. The real gem comes on Friday the 7th. The morning shows a 2 ft swell from the W, but the period is a very long 15 seconds, and the energy is strong at 315. This is proper groundswell, and it’s going to wrap in nicely on this reef. The wind stays light offshore, making for some absolutely glassy conditions. This is the best on offer, but remember, it’s a week and a half away, so keep an eye on it. Early Friday afternoon builds on that, with a 2 ft W swell, 16-second period, and energy at 380. The wind is still offshore. This is the one to circle.
The setup here is a reef break, so that long-period groundswell on the 7th will be a treat. It’s a fairly consistent spot, but it can get crowded sometimes, so be prepared to share the peak. With the swell staying under 5 ft, it’s manageable for strong intermediates, but the long period will make it punchy. For the experts, Friday the 7th is a no-brainer.
Alright, that’s the long and short of it. The swell is on its way, just got to be patient.
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.
