The Lowdown
Alright, this is Rusty.
Right off the bat, we’ve got a solid run of groundswell heading into Kuta Beach. The water is sitting at a warm 79°, which is pretty much spot on for this time of year, nothing unusual there. The first real action kicks off on Thursday the 20th of August. We’re looking at a big, powerful SSW groundswell pushing through with a very long period of 16 seconds. The combined energy is pumping strong at 3165, that’s a lot of power in the water. The swell is coming in at 8ft, so this is not for the faint-hearted – this is expert territory. The wind is a cross-off from the SE at 12 mph, which will keep the surface clean, but that size and power will be a handful. The crowd factor is trouble here too; it’s always busy, so be prepared to fight for your waves.
The swell backs off a touch into Friday, still packing a punch with 7ft and a 17-second period on the afternoon. The energy is still massive at 2832. It’s still a strong, clean, cross-off wind, but this is still a big, serious wave.
The standout opportunity appears on the 31st of August into the 1st of September. On Monday the 31st, the afternoon session sees the swell dropping to 6ft, but the period stretches to a massive 20 seconds. The combined energy spikes to 3616, which is very strong. The wind is light and offshore from the SE at 9 mph, so it will be glassy. That’s a beautiful, long-period groundswell with clean conditions. The following morning, Tuesday the 1st of September, is the absolute peak of the window. It’s an 8ft SSW swell with an 18-second period, and the energy is at a massive 3993. The wind is still light offshore from the SE at 9 mph. This is a true standout – big, powerful, and clean. Be aware, that long period at a beach break like Kuta can make the waves break a bit straight and close out, so it’s for the experienced crew who know how to handle it.
After that, the swell slowly eases through the first week of September. The 2nd and 3rd still have some fun, clean options in the 5ft to 6ft range with light winds, but the energy drops off a bit. The 4th of September has a nice little kick on the afternoon with 4ft, a 13-second period, and light offshore winds – that’s a fun, clean wave for the more intermediate surfer.
Overall, the first few days are heavy and for experts only. The real gem is that Monday the 31st of August through Tuesday the 1st of September window. It’s a long way out, so keep an eye on it, but that’s the one to circle on the calendar.

Information about the Kuta Beach Surf forecast
The above surf forecast table for Kuta Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kuta Beach can be found by selecting the local surf guide option on the grey menu. Our Kuta Beach 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 (Kuta Beach) 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 Kuta Beach 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.
Kuta Beach is 1 km (1 miles) from the city of Kuta. If you plan a holiday in Kuta - 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.
