The Lowdown
Alright, Rusty here. Let’s talk about the only game in town for this stretch: Sandtracks.
First things first, we’re looking at a solid run of frustrating conditions before things clean up. The water is sitting at a warm 81°, which is about average for this time of year here, so nothing out of the ordinary on that front.
We’ve got a long wait on our hands. From the start of the period right through to the end of the first week of September, it’s a write-off. The wind is stubbornly cross-shore, often a fresh breeze, and the surf is described as poor. Even Sunday the 5th and into the next week, the surf is listed as marginal, with moderate cross-shore breezes. The energy is there, with moderate to strong readings – but it’s all messy and lumpy.
Now, the real story starts to come together around Monday the 7th of September. The wind swings to a cross-offshore direction from the NE, and the swell starts to get some size. Tuesday the 8th is where it really fires up. We’re looking at a solid 14.8ft swell from the east with a 12-second period, and the energy reading is massive. That is strong, powerful groundswell. The wind is a moderate breeze from the NNE, so it’s a cross-offshore and clean.
This is expert territory. At 14.8ft, this isn't for the faint of heart. It’s a reef break that’s fairly consistent, so it’ll handle that size, but you need to know what you’re doing. The long period means it’ll be lining up nicely but with long lulls between sets.
If the big stuff isn't your game, keep an eye on Wednesday the 9th of September. The swell drops back to 7.5ft, but the wind goes to glassy conditions in the afternoon. It is flat calm. That’s an absolute gem of a window, and the conditions are described as excellent for experienced surfers. The energy is still solid, so there’s plenty of push, but the wind will make it perfect.
After that, things taper off through the second week. The swell drops and the wind turns more onshore or cross-onshore, leaving the surf marginal at best.
So, the standout is clear. If you’re a charger, Tuesday the 8th of September is the day for Sandtracks. Get on the 14.8ft east swell with that clean NNE wind. For everyone else, the glassy Wednesday the 9th of September afternoon session is your golden ticket.

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.
