The Lowdown

Alright, Rusty here, let's have a look at what's coming down the pipe for Sandy Beach.

Alright, look, I'm gonna be straight with you – the next week and a half is a write-off. It's a frustrating stretch of onshore ENE winds and lumpy, cross-shore chop that just won't let up. The combined energy is mostly moderate to strong, hitting a peak of (773) on the 27th, but with the wind howling from the wrong direction, it's all just a mess. Forget about it.

The first real glimmer of hope doesn't show up until Wednesday, the 2nd of September. The wind finally drops out. On Wednesday afternoon, we’re looking at glassy conditions with a tiny, but clean, 3ft groundswell out of the south with a long 16 second period. The energy is still moderate at (570), but that glassy surface is a major positive. The water temp is sitting at 80°, which is about normal for this time of year, so the rubber's not needed. The catch is, this is a very long-period south swell, which tends to break a little too straight on a beach setup like Sandy's, but with no wind it'll be the best we've seen in two weeks.

Thursday the 3rd of September offers a little more of the same, but a light east breeze creeps in, messing up that glass. We see a 2ft south swell (15 sec) in the morning and dropping to 2ft in the afternoon. The energy drops right off to (366) and (298), so it's getting weak.

Then, hold onto your board. The weekend of the 6th and 7th of September has a massive pulse of energy on the charts. Saturday the 5th sees the combined energy jump into the thousands, hitting (2133) by the afternoon with a 6ft east groundswell, but the wind is still a moderate cross-shore. The real monster is Sunday the 6th of September. The forecast is for a 10ft ENE swell, with a combined energy reading of (3652)! That is a very strong, powerful swell. The winds are forecast to be moderate cross-shore, which is alright, but a 10ft swell is expert-only territory at a beach break like Sandy Beach. It's going to be a heavy, closed-out mess for anyone without serious experience. The current is going to be a nightmare. Honestly, with that much power and a cross-shore wind, this setup looks more interesting for kite surfing than paddle surfing.

So, to sum it up: the standout window is the 2nd of September for a glassy, clean session on the small south swell. After that, the 6th of September brings a huge, expert-only swell that is more for watching than surfing if you're not a pro.

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.
