The Lowdown
Alright, I’m looking at what we’ve got for the next couple of weeks here, and mate, I’ve gotta be straight with ya – it’s a tough stretch. Kata Beach is the only break on the radar, but the whole 16-day window is looking pretty grim for a proper paddle.
Right from the get-go, Saturday the 29th through to the middle of September, it’s a constant battle against moderate to fresh cross-onshore winds, mostly out of the west. The swell that does show up is tiny – we’re talking 0.7 ft to 1.0 ft at best, with a very long period of 14 to 19 seconds. That long period means it’s a groundswell, but there’s just no height to work with, and the energy readings are weak, mostly in the 20 to 37 range and never getting past 86, so it’s flat and messy. The water temp is sitting at a warm 86° which is about average for the time of year, but that won’t help the surf.
The whole first week is a write-off: poor surf conditions, choppy, and lumpy with that wind. There’s a bit of a pulse around the 6th and 7th of September, where the swell bumps up to 3 ft to 4 ft, but the period drops to a short 6 seconds – that’s wind swell, and with the wind still hammering it, it’s just gonna be a messy, blown-out shorebreak. The energy climbs a little, hitting 86, but with the wind being cross-on, it’s not a pretty picture for a surfer. After that, it drops right back to nothing, with more days of zero swell and strong winds.
Honestly, there’s no standout session here. The swell direction is from the WSW and W, which is not matching the optimum SW direction for Kata Beach, and with the constant onshore flow, it’s just not gonna line up. For a beginner spot that’s already inconsistent, this run of poor conditions is tough. Given the combination of significant swell on the 6th and 7th, the poor quality, and the strong wind, the setup at this beach looks more interesting for kite surfing than paddle surfing. There are several blank days in a row, particularly from the 8th through the 13th, with no swell at all.
So, in short: keep the board in the bag. There’s nothing worth paddling out for in this forecast window.

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.
