The Lowdown
Alright, this is a bit of a tough one to call for Kata Beach. The whole 16-day window is looking pretty grim for a proper paddle session. You’re looking at a long stretch of small, messy, and mostly unsurfable conditions.
Right from the start on Wednesday the 26th of August, it’s a no-go. We’ve got a tiny 0.3ft trickle out of the SW with a long period of 16 seconds, but the energy is weak (only a 10) and the wind is a fresh cross-onshore. It’s lumpy and poor.
That’s pretty much the story for the next two weeks. Day after day, we see tiny waves in the 0.3ft to 1.0ft range, with the occasional spike in period from groundswells that just don’t have any grunt. The combined energy never gets above a weak 64 (on the 1st of September) for the first week. The wind is almost always a moderate to fresh cross-onshore, making everything choppy and ugly. For a beginner break that’s already *inconsistent*, this is a total flat spell.
The only blip of interest – and I use that term loosely – comes way out on Monday the 7th of September. A short-period windswell shows up, bumping the height to 3ft from the WNW, with energy just cracking into the moderate range at 120. But here’s the kicker: the period is a pathetic 6 seconds. It’s going to be a sectiony, weak, and bumpy mess, and it’s still showing poor surf conditions with a cross-onshore wind. That’s not for beginners, and even for the more experienced, it doesn’t look like much fun. The water temp is sitting at a warm 86°, which is about 2° warmer than normal for this time of year, so at least the wait is comfortable.
Honestly, for the entire outlook, there is no day where the stars align. The swell is tiny and weak, the wind is almost always wrong, and the quality is consistently poor. For a spot like this, such a blank run isn’t that unusual, but it doesn’t make it any easier to take. Maybe the kites will get a little something out of those stronger breezes, but for a surfer, leave the board at home.

Information about the Kata Beach Surf forecast
The above surf forecast table for Kata Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kata Beach can be found by selecting the local surf guide option on the grey menu. Our Kata 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 (Kata 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 Kata 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.
Kata Beach is 5 km (3 miles) from the city of Ban Chalong. If you plan a holiday in Phuket, look for hotels and other accommodation in Ban Chalong. Ban Chalong has rooms for a wide range of budgets as well as car hire and transport links.
