The Lowdown
Alright, mates, Rusty here. Let’s talk about the next couple of weeks. We’ve got one main spot lighting up the forecast, and it’s a proper one if you know what you’re doing. This is a season for the experienced crew, not the learners. We’re looking at a solid run of groundswell, with a few days that are going to be well worth the paddle out.
The standout period is clearly the middle of next week, starting around August 19th. That’s when everything lines up: the swell is pumping, the wind is offshore, and the break is handling it beautifully. We’re talking consistent, powerful waves with real push behind them. The energy in the water is going to be strong, with combined energy values hitting the 3400 to 3900 range (moderate to strong). The swell direction is SSW, which is exactly what this spot loves.
The first day of that run, Wednesday the 19th, is a beauty. You’ve got a 8ft swell in the morning with an 18-second period, and it holds in the afternoon at 8ft. The offshore ESE wind keeps things clean and lined up. This is a day for the advanced surfer who wants a serious session, not for the faint of heart.
But if I had to pick the very best day, it’s Thursday the 20th. The swell is a solid 8ft, still from the SSW, with a 16-second period. It’s a bit more consistent, and the strong offshore wind is holding all day. The energy readings are high, around 3400-3500 (moderate to strong), and the wave comment is spot on – excellent conditions for experienced surfers. The place is going to be busy, so expect a crowd, but the quality will be worth it.
There’s another interesting pulse right at the end of the second week, on Sunday the 23rd. The morning has a 6ft swell with a very long 22-second period. That’s some serious groundswell energy, and the combined energy value is huge at 4144 (strong). However, that long period can be a bit tricky – it might break a little too straight for some sections. The afternoon looks like it could get a bit messy, so if you're keen, the morning is your window.
Before all that, we have a solid run from the 12th through the 18th. It’s not going to be as perfect as the prime days, but there are still good waves on offer. The 13th and 14th look strong, with 7ft to 8ft swells and clean offshore winds. The 15th and 16th hold up well too, with the swell easing slightly but still offering powerful, clean surf. Just a heads-up, the afternoon of the 14th and the 24th have a cross-offshore wind, which can make things a little crumbly.
The last few days of the month, from the 25th onwards, start to ease off. The swell drops, the winds go more cross-off, and the energy fades. It’s fun, clean surf for the competent surfer, but nothing that will blow you away.
One thing to keep in mind: this is a reef and point break, and with these sizes and this much energy, it’s strictly for the advanced crew. If you’re not comfortable in powerful surf, give it a miss. But for those who are, this is going to be a fantastic couple of weeks. The long-period swells are going to make the paddling out easier between sets, but when they do come, they’ve got a lot of punch.
So there you have it. Get your good board, your best fins, and get ready for some proper surf. This is the kind of forecast that gets the stoke high.
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.
