The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming down the pipe for Racetrack, because this is a proper run of surf.
We’ve got a solid, consistent stretch of SW groundswell on the way, starting Friday the 11th of September and rolling through the entire 16-day window. No gap at the start; the waves are here from the get-go. This is a reef and point setup, so those long-period SW groundswells are going to line up beautifully. The energy is strong to very strong across the whole run, with combined energy values often sitting in the four-digit range, like 1865 (moderate to strong energy) and spiking up to 2637 (very strong energy). The water temp is about average for this time of year, so no surprises there.
The standout run is on Sunday the 13th of September. We’re looking at a solid 6ft to 7ft SW swell with a long 17 to 18 second period, and the wind is offshore from the ESE all day. That’s going to produce clean, powerful, well-shaped waves. The energy is peaking hard at 2557 and 2637. This is a classic point break session; the long period means the sets will be fat and lined up, and the offshore wind will keep the faces glassy. This is advanced territory with that size and power, but for the experienced crew, this is the best on offer.
The rest of the week is just as good. Saturday the 12th kicks off with 5ft SW and offshore winds, clean and consistent. Monday the 14th and Tuesday the 15th hold steady at 6ft to 6ft SW with the same clean offshore conditions. By Wednesday the 16th, the wind goes a little cross-off, but the waves are still excellent at 6ft to 6ft. The crowds here are always a factor, so expect company, but the quality makes it worth it.
Heading into the second week, the swell keeps pumping. Sunday the 20th of September sees a jump back up to 7ft SW, solid and powerful with offshore winds. That’s expert-only territory. The energy is back up over 2400. Wednesday the 23rd and Thursday the 24th also deliver 7ft SSW swells, with light winds, and the morning of Thursday the 24th is clean. The very end of the run, on Friday the 25th of September, we get a moment of pure glass: 6ft SSW with glassy conditions and a light breeze. That’s a magic window for the early birds.
Overall, Racetrack is firing for the next two and a half weeks. The consistency is high, the swell direction is spot-on, and the wind is mostly offshore. If you’re an advanced surfer, this is your time.
Rusty.

Information about the Racetrack Surf forecast
The above surf forecast table for Racetrack provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Racetrack can be found by selecting the local surf guide option on the grey menu. Our Racetrack 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 (Racetrack) 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 Racetrack 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.
Racetrack is 15 km (9 miles) from the city of Kuta. If you plan a holiday in The Bukit - Bali, look for hotels and other accommodation in Kuta. Kuta has rooms for a wide range of budgets as well as car hire and transport links.
