The Lowdown
Alright, Rusty here. Let’s talk about the stretch ahead for Kata Beach. The nutshell is a whole lot of nothing, with a tiny flash of something.
For the first week and a half, from Thursday afternoon the 30th of July all the way through to the afternoon of Monday the 4th of August, it’s basically flat. The combined energy is a zero. There’s a mix of light cross and onshore wind, and a few glassy moments, but no wave to speak of. Dead.
Then, out of nowhere, on Tuesday afternoon the 4th of August, we get a spike. A 1.9m swell from the WSW with a 9-second period. The combined energy hits 527 – that’s moderate energy, but a massive jump from the flat. The wind goes glassy, which is a huge plus. That’s the standout, and the only one. The water is 86°, a touch warmer than average for this time of year. That Tuesday afternoon is your only real shot.
But after that, it’s a grim run of 15 mph to 25 mph onshore winds, strong breeze conditions, and zero swell. The forecast stays rubbish right into the 14th of August.
Kata Beach is an exposed SW spot, so it needs that direction. It’s an inconsistent beginner break, so the lack of swell is pretty normal. That 1.9m is a bit much for beginners, and the 9-second period is short, so it’ll be a steeper, dumpier wave. But with glassy conditions, it’s the only game in town. Heads up, crowds are often possible here.
The rest of the run looks more interesting for kite surfing than paddle surfing given the wind and messy waves. A blank run like this is more normal for the area, so don’t get your hopes 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.
