The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the next couple of weeks at Sandy Beach.

Right off the bat, I gotta be honest with you – this is a tough one. The whole 16-day stretch is lookin’ pretty grim. We’ve got a massive gap right from the start, with no real surf on offer until the very end of the month. The wind is the main culprit here, blowin’ hard and from the wrong angles almost every single day. It’s a real shame, because there’s plenty of swell, but it’s all gettin’ chewed up.

For the first week and a half, it’s a write-off. From Friday the 14th all the way through to Wednesday the 27th, the conditions are just plain nasty. We’re lookin’ at strong cross-shore winds, often in the 18 to 31 mph range, which is gonna make the surface bumpy and messy. Even when the swell gets big – like on Sunday the 16th with a 12 ft swell from the East and a combined energy of 2504 (strong to very strong) – it’s all blowin’ out. That’s kite-surfing territory, not paddle surfing. There’s a brief moment on Sunday the 16th afternoon where the wind drops to 12 mph, but it’s still cross-onshore, and the surf is just marginal. The water temp is about average for this time of year, so nothin’ to get excited about thermals-wise.

Now, we finally get a little glimmer of hope right at the tail end. On Friday the 28th of August, the swell is still pumpin’ at 7 ft from the ENE, with a period around 10 seconds and a combined energy of 1075 (moderate to strong). The wind is still a fresh cross-shore at 22 mph, but it’s the best we’re gonna see. The score is still only a 1 out of 10, which tells you it’s barely worth paddling out. If you’re desperate for a wave and you’re an experienced surfer – because 7 ft is on the edge of big for a beginner – you might find a lumpy, closing-out wave. But honestly, the wind is still gonna make it a fight.

The standout? There isn’t one. If I had to pick the absolute least-bad session, it’s that Friday afternoon the 28th. The swell direction is a bit more east-northeast, which isn’t a perfect match for Sandy Beach’s optimum ESE direction, but it’s the closest we get to anything rideable. Expect crowds on the beach, but honestly, I doubt many will be in the water. This is a spot that’s fairly consistent, so a blank run like this is a bit of a downer, but it happens. Forecasts can change, and it’s a good time to clean the wax off your board and wait for a better window.

Rusty, signing off.

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.
