The Lowdown
Alright, folks, Rusty here. Let's be straight with you – the outlook for Sandtracks over the next couple of weeks is a bit of a mixed bag, and honestly, mostly a challenge. We've got a decent amount of swell energy pushing in at times, but the wind is going to be the main problem, turning what could be fun waves into a lumpy, choppy mess.
Looking at the whole picture, the first few days are a write-off. Sunday the 6th kicks off with some chest-high sets around 6 ft from the east, but that 30 km/h cross-shore wind is just going to shred it. The energy is there, with a combined swell energy reading of 1840, which is moderate, but it's not going to be any fun. It gets worse from there. Monday the 7th sees the swell jump to a solid 7 ft to 10 ft from the southwest, with a long 14-second period. That's proper groundswell, and the energy is strong (3514 to 4523). But with a fresh cross-onshore wind, it's going to be a big, blown-out mess. Only for the most hardcore, and even then, it's a struggle.
Tuesday the 8th is more of the same – onshore wind, messy conditions. We get a bit of a drop-off on Wednesday the 9th with smaller 3 ft swell from the SSW, and the wind swings onshore from the SE in the morning, which is at least clean, but the energy is weak (526). The afternoon might offer a slight window with a cross-shore, but it's marginal at best.
Now, here's the one small glimmer. Skip ahead to Sunday the 13th of September. The afternoon session at Sandtracks shows some promise. We've got a tiny 4 ft swell from the ENE, but the key here is the wind. It's a 20 km/h cross-offshore from the NE. The notes say "clean." That's the word we want to hear. The energy is weak (239), and the period is a short 7 seconds, so it won't be powerful, but if you want to get wet and have a clean, fun little wave, this is your best bet. It's the only window of truly clean conditions in the whole forecast.
After that, we're back into a long run of nothing special. From Monday the 14th all the way through to Monday the 21st of September, it's a constant story of moderate to fresh cross-shore winds from the ENE, lumping up a series of small, weak swells. The swell energy stays in the low hundreds to under 1000, which is weak. The waves will be there, but they'll be choppy and hard to enjoy. There's a long gap of over a week with no real standout recommendation.
The water temp is about average for this time of year. So, to wrap it up: don't get your hopes up for this two-week run. The surf is on, but the wind is off. The only day worth circling on the calendar is the afternoon of Sunday the 13th for a clean, if small, session. Otherwise, this is more of a window for the wind sports crew than a paddle surfer's paradise. Keep checking back, though – forecasts can change.

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.
