Alright folks, Rusty here. Let's get straight into it. We’re looking at Sandy Beach for the next couple of weeks, and I gotta be honest with you, the news isn't what we want to hear.
Looking at the whole run, there is not a single session rated as something you’d paddle out for. It’s a grim outlook, plain and simple. The wind is a constant problem. From Friday afternoon, July 3rd, all the way through to Saturday afternoon, July 18th, we’ve got a relentless cross-shore wind howling out of the ENE at 18 to 25 mph. That’s a stiff breeze to a strong breeze, and it’s going to tear the surface apart, leaving us with lumpy, messy, cross-chop every single day. There’s no let-up, no glassy morning window, just fresh to strong cross-shore wind ruining any chance of a smooth face.
The swell itself is a bit of a mixed bag, but the wind kills it. For the first few days, we see some ENE windswell in the 5 to 6 ft range with short periods of just 7 to 8 seconds. A couple of pulses show bigger numbers, like 7 ft on Monday and Tuesday (July 6th and 7th), with moderate wave energy showing up, but again, that raw power is completely wasted by the wind. On the flip side, there are smaller long-period south swells trying to sneak in, like 2 ft with a 20-second period on Saturday afternoon (July 4th), and a few bigger ones around 3 ft with 18-second periods on the weekend of July 11th and 12th. That kind of long-period groundswell would normally be magic, but with an 18-25 mph cross-wind, it’ll just be a bumpy, un-rideable mess. For a beach and reef setup like Sandy Beach, that long period stuff would need clean, calm conditions to be worthwhile.
The water temperature on the first day we have a reading is 79°F, so it’s right where you’d expect it for this time of year.
The bottom line is a tough one: we’ve got a solid 16 days with *zero* recommended surf. There’s simply no good option on the table. Unless the wind forecast changes drastically, leave the board in the car and don't even bother checking the cams. With this persistent wind and the beach/reef setup, if you’re really desperate for some time on the water, this looks way more like a kite-surfing setup than a paddle-surfing one. Conditions can always change, and it doesn’t often stay this poor forever, but for now, it’s a write-off.
Rusty.

Information about the Sandy Beach Surf forecast
The above surf forecast table for Sandy Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandy Beach can be found by selecting the local surf guide option on the grey menu. Our Sandy Beach 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 (Sandy Beach) 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 Sandy Beach 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.
Sandy's Beach is 15 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
