The Lowdown
Alright, let’s see what’s happening at Kata Beach for the next 16 days.
Look, I’m not gonna sugarcoat it – this is a rough patch. The whole 16-day window is a total bust for decent surf. There’s a long stretch of nothing worth mentioning, and I can’t pick out a single day or session that’s worth your time. The first hint of any energy shows up on Thursday, July 16th, but it’s so small it’s barely a whisper.
The only spot we’ve got is Kata Beach. It’s an inconsistent beginner break, open to the SW. Water temp is about 86°F, which is pretty normal for this time of year – nothing wild.
Let’s break it down. Wednesday the 15th is a total washout – thunderstorms and flat calm. Thursday the 16th morning offers a tiny 0.7ft groundswell from the WSW with a super long 16-second period, and the combined energy is weak (26). The wind is glassy, so it’d be clean, but with that size, you’re looking at knee-high slop. Friday the 17th and Saturday the 18th are similar – 0.7ft swell, weak energy (25 and 22), but the cross-onshore wind picks up, making it choppy. Sunday the 19th afternoon sees a bump to 3ft from the W, but with a terrible 5-second period, it’s just wind-chop, and cross-onshore wind at 15 mph makes it a messy, blown-out disaster. The combined energy is still weak (54).
From Monday the 20th through Friday the 24th, it’s all zeros – flat. Some glassy mornings, but nothing to ride.
Saturday the 25th morning brings a tiny 0.3ft, 15-second groundswell from the SW, but the combined energy is a measly (9). Still not worth the walk. The rest of the run up to the 30th is more of the same – tiny 0.3ft to 0.7ft swells, weak energy, and mostly cross-onshore wind. The wind cranks up to 19 mph on the 27th and 28th, making it lumpy and unpleasant.
With the persistent strong cross-onshore wind and tiny, weak swell, this setup honestly looks more like a kiteboarding session than a paddle surf session. There’s just no power or clean face to be had.
So, bottom line: leave the board at home. Forecasts can change, but right now it’s a flat spell with a few unrideable blips. Keep an eye on it, but don’t get your hopes up.

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.
