The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for the Kata Beach area over the next couple of weeks. Gotta be straight with you – the outlook is a tough one. We're looking at a whole lotta nothing for a long stretch, so patience is the name of the game.
The first signs of any swell at Kata Beach show up on the afternoon of Thursday, August 13, but it’s barely a whisper. The real story for the first week is a long, dry spell with no rideable waves. The wind is hammering in from the west and west-southwest, blowing cross-on shore, and the sea’s just a mess of chop and lumpy conditions. Water temp is sittin’ around 86°, which is about normal for this time of year.
We finally see a pulse of long-period groundswell from the southwest starting on Saturday, August 15. But even then, we’re talking tiny, weak waves – the combined swell energy is only a paltry 24 (weak). The wind is still a fresh 19 mph cross-onshore, so it’s gonna be bumpy and tough.
The best part of this whole 16-day window is shaping up to be Wednesday, August 19. We get a little bump in size to 1 ft from the WSW with a very long 20-second period. The combined energy climbs to 77 (still weak, but it’s the most we see). The wind is still a fresh cross-onshore though, which will mess with the shape. For a break that’s exposed to the SW, this is the peak, but it's small and choppy. Kata Beach is an inconsistent spot to begin with, and this run proves it. Honestly, with the persistent wind and weak, messy surf, this setup looks more interesting for a kite surfer than a paddle surfer. Hang tight, this blank run is the norm here sometimes. It can change though, so keep an eye on it.
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.
