The Lowdown
Gather round, crew. Rusty here, and we've got one hell of a forecast window for the Racetrack. This is a proper, exposed reef and point setup that knows how to handle a south-west groundswell. The water's sitting at a comfortable 79°F, which is bang on average for this time of year, so no surprises there. We're looking at a solid run of surf starting from the first day of the month and rolling all the way through, with no real flat spells to worry about.
Alright, let's get into it. This first week kicks off proper. Tuesday the 1st of September, we've got a clean 7ft swell from the SSW with a very long period of 18 seconds – that's proper groundswell energy, 2523 on the energy meter. The wind is a fresh offshore from the ESE, which will groom those faces beautifully. It's a heavy spot though, deep water, expert-only territory with that size and power. Crowds are always an issue here, so expect company. The water temperature is normal, so it's wetsuit territory.
Wednesday the 2nd holds steady with a 6ft SW swell at 16 seconds, still very clean with a moderate ESE offshore in the morning. Thursday the 3rd brings a 5ft SW swell, still with 16-second period and clean offshore conditions. The energy drops a bit (1186), but it's still a damn good session for the experienced surfer.
Friday the 4th sees a dip to 4ft SW, 14 seconds, but still clean offshore in the morning. The afternoon turns cross-offshore, which starts to put a bit of texture on it. Saturday the 5th and Sunday the 6th see the swell pulse back up, hitting 7ft on Sunday morning with a 17-second period and strong energy (3163). The wind is cross-offshore though, so while the swell is there, it's not pristine.
Now, here's the standout. Circle Tuesday the 8th of September in your calendar. This is the one. We've got an 8ft SSW swell with an 18-second period – that's massive, deep-water energy (5472). The morning has a moderate offshore from the SE, making it as clean as you'll ever see at this break. This is expert-only territory; at 8ft, it's dangerous for anyone without serious experience. The afternoon turns cross-offshore, but that morning session is going to be etched into memory.
After that, the swell stays solid through the second week. Wednesday the 9th has 8ft at 16 seconds, Thursday the 10th has 7ft with gentle offshore in the morning, and it keeps pumping through the end. Friday the 12th of September is another one to look out for – a 5ft SW swell with a 15-second period, moderate offshore wind, and the energy is still solid at 1335, making for excellent conditions for experienced surfers. The second week runs consistent, with the weekend of the 12th-13th offering another nice clean window on the Saturday afternoon and Sunday morning.
Overall, this is a classic run for the Racetrack – exposed to the south-west, it's going to be on. The only caveat is those super-long period swells (18 seconds) can break a bit straight here, but on a reef and point set-up like this, it'll just mean longer, more powerful lines and easier paddling between sets. Get on it.
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.
