The Lowdown
Alright, Rusty here again. Let’s talk surf.
We’ve got a solid run starting Sunday morning and going for days. The standout is Racetrack, a reef and point that loves a south-west swell. Water temp is 78°, a bit cooler than usual.
Sunday morning brings 6ft SSW swell, 15 seconds, clean offshore wind at 16 mph. That’s excellent for experienced surfers, with moderate to strong energy (1986). Sunday afternoon is similar, energy a bit higher (2256). Monday and Tuesday keep the quality – 6–6ft SSW, 15–16 seconds, clean offshore winds. This is the sweet spot.
Wednesday drops a touch to 5ft, still clean. Thursday afternoon is a gem – 4ft swell with a 20-second period, 2876 energy. Long, powerful groundswell and a light offshore. Friday 28 August morning is the biggest – 8ft SSW, 16 seconds, 3731 energy. That’s strong. Offshore in the morning, but strictly for experts.
Saturday 29 August still has 6ft and clean conditions. The following week sees size drop but plenty of clean windows. Monday 31 August has 3ft swell with a 19-second period – super long-period groundswell, best on the point. Early September brings another pulse of 6–7ft SW swell with 16–17 seconds and consistent offshore winds.
There’s a lull around Thursday 3 September afternoon into Friday with smaller 4–5ft swell and cross-off winds. The energy picks up again Sunday 6 September with a 7ft SSW swell, but the wind is cross-off.
Best of the bunch: Sunday 23 August morning for that first clean, long-period groundswell, and Friday 28 August morning for the biggest, most powerful swell. Crowds are always heavy at Racetrack, so be early.
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.
