The Lowdown
Alright folks, Rusty here, and I’m not gonna sugarcoat it – the next couple of weeks at Sandtracks are looking pretty rough. The whole 16-day window is basically a no-go for clean, rideable waves. We don’t even get a single decent session to kick things off.
Let’s break it down. The first real swell shows up on Monday the 7th of September with a 5ft SW swell, but it’s coming in with a 30 km/h cross-on ESE wind. The water’s warm at 81°, which is about average for the time of year, but you won’t be enjoying it. The combined swell energy is strong at 1644 (moderate to strong wave energy), but the wind has it all chopped up and lumpy. That afternoon, it actually builds to 8ft with a 14-second period, and the energy jumps to 4124 – that’s serious power. But again, it’s blown out by a 35 km/h cross-on wind. That kind of size and onshore wind is just messy.
Tuesday the 8th keeps the same theme. Morning has a 8ft SSW swell (period 9 seconds) with a 30 km/h cross-on wind, and the energy is 2131. Afternoon drops to 6ft but the wind is still cross-on at 20 km/h. Not a single window of clean conditions.
Wednesday the 9th sees the swell drop right off to 3ft, but it’s a long-period 14-second groundswell. The energy is weak at 483. The morning has a light cross-on breeze, just a bit of wind ripple, but it’s still cross-on. The afternoon is labeled “marginal” – that’s the best we get, and it’s a 1 out of 10. Not worth paddling out.
From Thursday the 10th all the way through the end of the 16 days, it’s a never-ending loop of cross or cross-on winds, mostly from the ENE, with small to moderate swell. The swell heights bounce between 1ft and 7ft, but the wind is always in the wrong direction. The energy values range from as low as 112 (very weak) up to 1201 (moderate to strong), but it doesn’t matter because the wind keeps it a complete mess.
There’s a period around the 18th and 19th of September where the swell gets up to 7ft to 7ft from the E, with a short 8-second period. The wind is howling from the ENE at 40 km/h, so that’s more of a kite-surfing setup than a paddle-surfing one. The energy is strong, peaking at 1201, but it’s just not surfable.
The only highlight that’s barely worth mentioning is the afternoon of the 9th of September – a 3ft, 13-second swell with light wind. It’s marginal, but that’s as close to clean as we get. Even then, it’s still cross-on.
Honestly, Sandtracks is a reef break that’s fairly consistent, but with this persistent cross-shore wind from the ENE, it’s just not going to happen. The swell direction is mostly from the S to SW, which is the optimum, but the wind is the enemy. There’s nothing to get excited about here. The whole forecast is a bust.
Rusty.

Information about the Sandtracks Surf forecast
The above surf forecast table for Sandtracks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandtracks can be found by selecting the local surf guide option on the grey menu. Our Sandtracks 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 (Sandtracks) 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 Sandtracks 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.
Sandtracks is 3 km (2 miles) from 'Ewa Beach. If you plan a vacation in Oahu, look for hotels and other accommodation in 'Ewa Beach. 'Ewa Beach has rooms for a wide range of budgets as well as car hire and transport links.
