Table - best surf conditions forecast for Kata Beach over the next 16 days.
Alright folks, Rusty here. Let’s be straight with you – it’s a grim run for the next 16 days at Kata Beach. I’ve looked it over and there’s nothing to get excited about. The whole stretch is a bust.
The forecast kicks off Thursday, July 9th, with a tiny 0.7 ft swell from the WSW, but it’s a 15-second period groundswell. That long period might sound good, but with a cross-on W wind blowing 16 mph, the water’s chopped up and messy. The combined energy is a weak 21, and the water temp is 86°, which is pretty average for this time of year. Honestly, it’s poor surf and the score is a zero. Don’t bother.
Friday, July 10th, is even worse. The wind picks up to 19 mph, still cross-on, and the swell is barely a pulse. Same story for the rest of the week. We get a thunderstorm threat on Sunday, July 12th, and into Monday, July 13th, with onshore winds. There’s a moment on Tuesday morning, July 14th, with a tiny 0.7 ft SSE swell at a short 4-second period – that’s junk, with a combined energy of just 2. Light breeze, but still no good.
From Wednesday, July 15th, all the way through to Friday, July 24th, the pattern is locked in. West to west-southwest winds between 16 and 22 mph, mostly cross-on, and zero swell. The forecast shows "poor surf conditions" across the board. There’s a tiny 0.7 ft pulse on Thursday, July 16th, with a 16-second period giving a combined energy of 26, but the wind is fresh and cross-on. It’s not worth a paddle.
Kata Beach is an inconsistent spot, and this is a classic blank run for the area. It’s just not happening. With the constant cross-on wind and no real swell, it’s honestly looking more interesting for kite surfing than paddle surfing. Keep your gear waxed and hope the forecasts change. 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.
