The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of swell on the cards for Racetrack, so if you’re an advanced surfer, you’re gonna want to pay attention.
The overall pattern is a persistent, long-period SSW groundswell that builds mid-week and just keeps on giving. The water temp is sitting at 79°, which is about average for this time of year, so no surprises there.
The fun kicks off on Friday the 4th with a 5ft SW swell, but it’s a bit of a warm-up. The real action starts Saturday the 5th. Saturday morning we’re looking at 7ft from the SSW with a 16-second period, but the wind is cross-off from the SE at 12 mph – it’s clean, but not perfect. The wave energy is strong (2007).
Sunday the 6th morning is where it starts to get good. That swell is 7ft from the SSW, with a 17-second period – that’s proper groundswell – and the wind swings offshore from the SE at 12 mph. This is a standout morning for experienced surfers. The wave energy is very strong (2844). Sunday afternoon drops off a touch.
The middle of the week is a bit of a grind. Monday through Thursday sees plenty of 7ft to 8ft SSW swell, but the wind stays cross-off, keeping things clean but not glassy. The combined energy stays strong, ranging from 1844 to 2962. It’s surfable, but you’re working for it.
Now, the true standout is Sunday the 13th. That morning we’ve got an 8ft SW swell with an 18-second period, and the wind is a clean offshore from the SE at 12 mph. The wave energy is massive (3747). This is big, powerful, and very clean – expert-only territory. The afternoon is similar at 8ft, but the wind goes cross-off.
Monday the 14th and Tuesday the 15th are still excellent, with offshore winds in the mornings and 7ft to 6ft swell. Solid, clean, and consistent.
The second week keeps the momentum going. Wednesday the 16th to Friday the 18th are a mix of offshore and cross-off winds, with swell from 4ft to 6ft. The wave energy is still moderate to strong (1191 to 2373). It’s reliable, but not the standout size of the first week.
The final highlight is Saturday the 19th. That morning we’re looking at 7ft from the SSW with a 16-second period and offshore wind. The energy is huge (2769). Saturday afternoon might be the best of the whole run: 8ft from the SSW, 16-second period, offshore wind, and the wave energy is absolutely pumping at 4089. This is a serious, clean, powerful swell for the experienced crew.
Remember, Racetrack is a reef and point break, exposed to the swell, and it’s very consistent. That long period swell is going to be perfect for the point setup, giving you long, walled-up rides. But be aware, crowds are always there, so get in early.
Keep in mind, the further out we go, the less certain the detail, but the signs are very promising.
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.
