The Lowdown

Gather 'round, folks. Rusty here. I'm looking at the 16-day forecast for Sandy Beach, and I gotta be straight with you – it's a tough stretch. The pattern is locked in: a persistent, strong onshore wind and a messy cross-shore chop that's gonna make things ugly for the foreseeable future. The water is sitting at a pretty standard 80°, which is right on the money for this time of year, so no surprises there.

The first real standout? There isn't one. The whole first week, from Monday the 31st of August right through to the end of the first week, is a write-off. We're looking at 7 ft to 10 ft of short-period, 7 to 8-second ENE wind swell, but it's all blown out by fresh to strong breezes from the ENE. The wave energy is moderate to strong, hitting values like 640, 918, and even 1622, but it's all messy. The wind's cross-shore, creating lumpy, messy cross-chop. It's poor surf conditions, plain and simple. The water's a standard 80°, and there's not a single good wave in the bunch.

Then we get into the second week. There's a tiny glimmer of hope on Monday the 7th of September afternoon. The wind swings to a cross-offshore from the north, still a fresh breeze, but it's enough to clean things up a bit. The swell is a 7 ft ENE groundswell with an 11-second period, and the energy is strong at 1896. It's still only a marginal call, but it's the best we're gonna see. The swell direction is coming from the ENE, which is close to the ESE optimum for Sandy, so the shape might be okay, but it's a beach and reef setup, so don't expect perfection. Crowds are often a problem here, so if you're thinking about it, be prepared for company.

After that, things get worse. The wind switches back onshore, and the swell drops off fast. From Tuesday the 8th all the way through to Tuesday the 15th, we're looking at small, weak, blown-out junk. The swell height drops to 2 ft to 2 ft, the period is all over the place, and the energy is weak (186 to 334). It's a long, blank run of poor conditions.

Honestly, for the whole 16 days, the only session that even hints at being rideable is that Monday afternoon, and it's a marginal call at best. The setup is more interesting for kite surfing than paddle surfing, given the persistent strong winds and messy waves. For a surfer, it's a tough forecast. You might want to take a break.

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.
