The Lowdown
Alright, let me be honest with you. It’s Rusty here, and I’ve looked over the charts for Kata Beach. To be straight with you, this forecast window is a real bummer. We’re looking at a long, flat run with nothing worth paddling out for right through the entire 16 days.
The first few days are a write-off. Friday the 24th we’ve got a bit of swell showing, but it’s short-period windswell around 2.9 to 3.6 ft from the west, and the wind is a messy cross-shore at 12 mph. It’s choppy and lumpy, and the wave energy is weak (45 in the morning, 74 in the afternoon). It’s just not surfable. The water’s warm though, sitting at 86.9°, a touch warmer than normal for this time of year.
Saturday the 25th and Sunday the 26th are more of the same – the swell tries to push up a bit, with heights up to 4.6 ft on Saturday afternoon, and the energy climbs to moderate levels (150-164), but the wind swings onshore and gets fresh at 18-22 mph. It’s a rough, blown-out mess. Don’t bother.
Then we hit a major gap. From Sunday the 26th afternoon right through until Wednesday the 30th, the swell completely dies. Zero energy, zero waves. Just lumpy, onshore wind and the risk of thunderstorms.
We do get a tiny pulse on Thursday the 31st and Saturday the 1st of August, with some very long-period groundswell showing up – we’re talking 16 to 18 second intervals from the WSW. But the heights are tiny, only 0.6 ft, so there’s nothing to ride. The energy readings are low (33-36) and the conditions are still poor. That long-period swell of 18 seconds is the kind of energy that would wrap nicely around a point or reef, but at this break, it’s not doing anything.
The rest of the first week of August is a washout. Swell stays tiny, winds stay strong and onshore, sometimes hitting 25 mph. The setup here is a beach exposed to the swell, and with the wind and chop, it looks more interesting for kite surfing than paddle surfing during those stronger wind days.
Honestly, there are no good surf options in this entire 16-day window. Kata Beach is an inconsistent spot, and this stretch of poor conditions is a normal part of the pattern here. Forecasts can change, but right now, it’s a flat spell. Keep the board in the bag.

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.
