The Lowdown
Alright folks, Rusty here. Let’s be straight with you – the outlook for the next couple of weeks is a tough one to swallow. I’ve scanned the charts and, honestly, there’s not a single solid window for a proper paddle. We’ve got a long, dry gap stretching from now until the end of the 16-day window. The first real chance of anything surfable comes and goes, but it’s a no-go.
Let’s start with what we’ve got. The only spot on the radar is Kata Beach. It’s an inconsistent beginner’s break, exposed to the southwest, and it rarely kicks into gear. The water temp is sitting at 86°, which is about average for this time of year.
The first blip of energy appears on Thursday, August 6th, in the morning. We’ve got a 4ft swell from the WSW, but the period is a mediocre 9 seconds, and the wind is howling onshore at 16 mph from the same direction – it’s going to be a choppy, blown-out mess. The combined energy is moderate (193), but you’d be fighting a losing battle. The forecast says “poor surf conditions” and that’s the truth.
The rest of the month is a dust bowl. After that Thursday morning, it’s a long stretch of flat-to-minuscule waves. You’ll see pulses of 0.3ft to 0.7ft with very long periods (16 to 19 seconds), but the wind is consistently cross-onshore, gusting from 16 to 25 mph. There’s even a strong breeze up to 28 mph on Thursday, August 20th, with a 1ft swell. The energy is weak (61), and it’s just not worth the effort. Honestly, with the wind and the tiny, gutless swell, this setup looks more interesting for kite surfing than paddle surfing.
So, bottom line: there’s nothing to recommend here. The break is inconsistent at the best of times, and this run of poor conditions is pretty normal for the area. Don’t hold your breath. Forecasts can change, but right now, I’d keep the board in the car and wait for a better day.

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.
