The Lowdown
G’day, Rusty here, and I’ve got a gem of a run for us. Racetrack is a reef and point break that’s very consistent and exposed to the south-west swell, making it a proper advanced spot. The water’s sitting at 79°F, which is pretty much bang on average for this time of year, so no surprises there. The ride starts on Wednesday the 26th with a solid 5ft swell from the SSW, but that first morning is only marginal with a moderate offshore breeze, so don’t get too excited yet. By Wednesday afternoon, things pick up with that same 5ft swell and cleaner conditions, giving us a decent taste.
Thursday the 27th is where it gets interesting. The morning brings a 4ft swell from the SW with a long 16-second period and a moderate offshore wind, making for clean, powerful waves. The energy is moderate (1330), and the water’s holding steady. By the afternoon, the swell jumps to 6ft from the SSW, with a 15-second period and a gentle cross-off breeze, keeping it clean. The energy ramps up strong (2996), and this is shaping up to be a top session for experienced surfers.
Friday the 28th is the standout. The morning has a 8ft SSW swell with a 16-second period, a gentle offshore breeze, and a huge energy reading (3613). That’s strong, powerful groundswell, and it’s going to be a ripper for the advanced crew. The afternoon holds the same size and period, just a touch less energy (3046), but still excellent. Saturday the 29th eases a bit with 6ft SSW swell in the morning, a long 15-second period, and a cross-off breeze, staying clean with moderate energy (1529). The afternoon drops to 5ft SW, but still clean.
We roll into Sunday the 30th with a 5ft SSW swell, a 13-second period, and a moderate offshore breeze, keeping the waves clean and the energy around 1017. Monday the 31st brings a risk of thunderstorm in the morning, but that 4ft SSW swell with an 18-second period is a beauty of a long-period groundswell, and the offshore wind keeps it tidy. The energy is moderate (1460). The afternoon pushes 6ft SSW with the same 18-second period and stronger energy (1892).
Tuesday the 1st of September sees a 7ft SW swell in the morning with an 18-second period, but the wind picks up to a fresh breeze, so it’s marginal. The energy is strong (2600), but that wind might mess with the shape. Wednesday the 2nd has 6ft SW swell with a 17-second period and a moderate offshore breeze, energy around 1994, but it’s still marginal. The afternoon drops to 6ft SW with a 16-second period and cleaner conditions, edging back into excellent territory.
Thursday the 3rd and Friday the 4th keep the swell around 4ft to 5ft from the SW, with moderate offshore winds, but the energy slides down to 585 to 1180, so it’s more mellow. Saturday the 5th and Sunday the 6th build back up, with Sunday the 6th hitting 6ft to 7ft from the SSW, a 16-second period, and strong energy (1876 to 1978) with a moderate offshore breeze. That’s a solid Sunday.
The best of the best is Thursday the 27th afternoon and Friday the 28th morning. The 28th morning has that 8ft SSW swell, 16-second period, gentle offshore wind, and energy over 3600—it’s big, clean, and powerful. For advanced surfers, that’s the one. The 9th of September also looks a cracker, with a 8ft to 8ft SSW swell, 16-17 second period, and gentle offshore or cross-off winds, energy over 3000, but that’s a bit further out, so keep an eye on it.
Crowds at Racetrack are always present, so get in early. The long-period swells from the SSW will wrap nicely into this reef and point setup, so expect well-shaped, powerful waves with longer gaps between sets. Over 8ft, it’s strictly for experts, and with the energy levels we’re seeing, this is a run for the experienced crew.

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.
