The Lowdown
Alright, let me tell you how it is. This is Rusty, and I’m looking at the next 16 days for Kata Beach. To be honest, it’s a rough stretch. The ocean is putting out a whole lot of nothing, and the wind is going to be a problem too.
For the first week, starting Tuesday the 21st, we’re staring at a flat spell. The water is a warm 86°, which is about a degree and a half warmer than usual for this time of year, but that’s the only highlight. The swell is barely a ripple, and the wind is hammering out of the west, cross-onshore, making for a choppy, messy surface. There’s just no energy to work with.
This pattern of poor surf and choppy, uninviting conditions drags on with no real break. The wind picks up to 18 and 22 mph, still cross-onshore, and the occasional thunderstorm just adds to the misery. The swell energy sits at weak numbers, often in the single digits or low tens, and sometimes there's no swell at all. We’re looking at a solid week of this, with nothing to get excited about until the very end of the month.
Things get a little weird on the 31st of July (Friday) and into the 1st of August. The swell direction swings to the WSW, and the period jumps up to 17-19 seconds, which is a very long period groundswell. But the height is tiny, only about 0.7 ft. The combined energy is still very weak, at 34 and 64. It’s a tease. The wind is still onshore or cross-onshore, so even if there was power, the face would be a mess. This is not a surfable setup.
The entire 16-day window is a bust. There are no standout days, no clean windows, no good waves. The only thing you can count on is the warm water. For a spot that’s inconsistent, this kind of blank run isn’t totally unusual, but it’s a real bummer. I’d say find something else to do with your time. The kite surfers might have a bit more fun with the wind, but for us paddle surfers, it’s a hard pass.
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.
