The Lowdown
Alright folks, Rusty here. Gotta be straight with you – the next couple of weeks are looking pretty grim for a paddle. Let’s get into it.
We’re looking at a real dry spell to kick things off. From the start of the period right through to the 7th of September, there’s just nothing doing. The combined energy is flat-lining at zero for most of those days, and while a tiny 0.7ft to 2ft bump tries to show up, it’s all wind-affected and junk. You’d be fighting a cross-onshore breeze that’s making a mess of things. It’s a tough stretch.
Into the second week, things don’t really improve. We get a couple of pulses on the 10th and 11th, but they’re tiny – 0.3ft to 0.7ft – with a super long period of 15 to 16 seconds, which is a groundswell. The problem is, the wind is still howling onshore, 15 to 22 mph, making it lumpy and rough. The energy is weak (10 to 25). Then on the 12th, we see a little more energy, with a combined swell energy of 124 for the afternoon on a 1ft, 21-second swell from the WSW. That’s a very long-period groundswell, but again, it’s buried under a fresh cross-onshore breeze. The whole setup is so blown out and weak that for a beach break like Kata Beach, this is genuinely more interesting for kite surfing than trying to paddle a surfboard.
The best of a bad bunch might be the very end of the forecast, on the 16th of September. We’ve got a clean, cross-offshore wind from the NNW, at 9 to 12 mph. The swell is still tiny, only 0.7ft, and it’s a 15-second period groundswell from the WSW. The combined energy is weak (24). It’s clean, but you’re probably looking at ankle-biters. It’s the only time the wind co-operates, so if you’re desperate, that Wednesday morning is your window. The water temperature is sitting at 86°F, which is about average for this time of year.
Bottom line: it’s a long, flat, and windy outlook. The whole 16-day window is a struggle. There’s no standout, no hidden gem. Just a lot of poor surf conditions. The only real positive is that the wind finally looks like it might turn clean for a day, but the swell just isn’t there to back it up.
Rusty.

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.
