The Lowdown
Alright folks, Rusty here. Let’s get straight into it. We’ve got a 16-day window to look at for Kata Beach, and honestly, it’s a tough one. The first few days are a write-off – no swell to speak of, just messy, cross-onshore winds and a lot of stormy talk. We’re looking at a gap of about a week before we even see a pulse of energy.
The first real sign of life shows up on the 7th of September. Tuesday morning, we’ve got a WSW swell creeping in at 4 ft, but it’s a short-period, choppy 6-second windswell. Combined energy is weak (75). The wind is cross-onshore at 12 mph, so it’s messy. Not worth paddling out for. Tuesday afternoon is similar – 4 ft, 6-second period, still cross-onshore and lumpy. Not a standout.
Wednesday the 8th sees a bit more size, 5 ft, but still that same short-period stuff. The combined energy nudges up to 130 (moderate), but fresh cross-onshore winds at 15-18 mph are going to ruin any chance of a clean face. Honestly, for a beach break, with that wind and chop, it’s looking more interesting for kite surfing than paddling.
The only other bit of swell we see comes on the 13th of September – Sunday morning. A long-period groundswell from the WSW at 1.0 ft but with a period of 19 seconds. Combined energy is 146 (moderate). Now, that long period is a promise of better shaped waves, but with such a small height and strong cross-onshore winds at 25 mph, it’s gonna be blown out and messy. For a spot that’s inconsistent and exposed, it’s just not enough to get excited about.
The water temp is sitting at 86°, which is about normal for this time of year (1° anomaly). So at least the water’s warm if you’re just having a swim.
The bottom line: There’s nothing here that qualifies as a standout. The entire 16-day run is plagued by poor surf conditions and onshore winds. If you’re desperate, that 5 ft pulse on the 8th is the biggest, but don’t expect any quality. Kata Beach is a tough bet this period.
Rusty out.

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.
