The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid long-range window of consistent, clean, groundswell on the way for Kuta Beach. It’s gonna be a big-swell, expert-only show for the first part, then slowly settle into something more manageable. The water is sitting at a warm 79°, which is pretty much bang on average for the time of year, so no surprises there.
The action kicks off Wednesday morning, August 19th. We’re looking at a very strong 7ft SSW groundswell, with a long 18-second period. The energy is pumping hard (3073), so this is powerful stuff. The wind is a clean, cross-off SE breeze at 9 mph, meaning the face will be smooth. But listen, at this size, with that period, this is strictly for experienced surfers only. The swell direction is SSW, which is a touch off the optimum SW, but it’s still going to wrap in nicely. Kuta Beach is consistent and always crowded, so expect a full lineup.
The swell peaks a little on Thursday morning, August 20th, hitting 8ft from the SSW with a 16-second period. The energy is still massive (3173). The wind stays cross-off, but it picks up to 12 mph. This is straight-up expert territory. It stays big and powerful right through the weekend, with swell holding around 7ft to 7ft and clean cross-off winds. The best session of this entire first week is probably Wednesday morning, August 19th – that 18-second period and glassy cross-off wind is a beautiful combination, even if it’s a bit heavy.
Into the second week, the swell drops a notch. By Monday, August 25th, we’re at 5ft to 6ft, still with clean cross-off breezes, but the energy is fading (1115). This is where it gets fun for the average surfer. The standout for the whole run might actually be Monday afternoon, August 31st. A new pulse of SSW groundswell comes through at 6ft, but look at the period – 20 seconds! That’s a very long-period groundswell, and the energy jumps back to 3167. The wind is clean cross-off. This is the one to circle on your calendar. It’s a week and a half out, so not a lock, but it looks promising.
Tuesday, September 1st keeps the energy up with 7ft SSW swell at 18 seconds and clean winds. After that, it slowly winds down. The last few days of the forecast see a drop in size, but still clean, with a nice little 6ft pulse on Thursday afternoon, September 3rd.
Overall, it’s a great run. The first week is for the chargers, the second week has a couple of classic, long-period gems for the rest of us. Keep an eye on that August 31st date.

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.
