The Lowdown

Alright, this is Rusty comin' at ya. Let's get into it.

Alright, listen up. We've got a solid run of surf on the horizon. It's not gonna be flat, not by a long shot. The water is a warm 78°, which is just a touch cooler than normal for this time of year, but honestly, you won't feel it.

The place to be is Racetrack. This is a reef and point setup, holding a lot of that southerly energy we're about to get. It's an advanced wave, just so you know, and it's *always* crowded, so be ready to share.

The action kicks off on Monday afternoon, August 17th. We're looking at a clean 5 ft swell from the SSW, with a clean ESE offshore breeze. The combined energy is moderate (893), so it's a nice warm-up.

Then it really starts to build. From Tuesday, August 18th, through the week, the swell pumps up. You'll see waves from 6 ft to 8 ft, all from the SSW or SW. The period is long, 14 to 18 seconds, meaning these are proper groundswells with some real power. The combined energy gets into the thousands (2428 to 4101), so you're feeling it. The wind holds steady from the ESE, offshore, keeping it all clean. This is the meat of the run.

The peak of this first pulse hits around Wednesday, August 19th, and Thursday, August 20th, with 8 ft to 8 ft swell. This is big, expert-level stuff. For the average surfer, it's gonna be a handful. The wind is light and offshore, so the face will be like glass.

Things ease a touch over the weekend, but it's still solid - 5 ft to 8 ft of swell, same clean conditions. There's a little drop in quality on some afternoons due to a cross-offshore wind, but the mornings are your best bet.

The standout, the one you circle on the calendar, is the final Sunday and Monday, August 30th and 31st. We get a new pulse of energy, with the swell hitting 7 ft on Sunday and then getting a massive injection of power. The combined energy spikes to 2336 on Sunday, then jumps to an incredible 3469 on Monday morning, and 4218 on Monday afternoon. The period on Monday morning is a very long 21 seconds, which is going to create some beautiful, heaving lines at this point break. The wind is clean and offshore. This is the one to wait for. Then it carries on into Tuesday, September 1st, with 8 ft swell from the SW.

So, the pick of the bunch is Monday, August 31st, at Racetrack. Get in the water early, expect a crowd, and prepare for some of the best waves of the season.

This is Rusty, signing off.

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.
