The Lowdown

Alright folks, Rusty here. Let’s take a look at what’s cooking at Kata Beach over the next 16 days.

Honestly, I’ve got to be straight with you – there’s nothing on the table worth paddling out for. The whole forecast window from July 18 right through to August 2 is a total dud. Not a single session with even a hint of decent surf. Every day is flagged as poor surf conditions, so we’re looking at a solid 16-day gap with no recommendations. That’s a long stretch of flat or messy water.

Kata Beach is a beginner-friendly spot, but it’s inconsistent and can get crowded often. The swell direction that works best is from the southwest, and the place is exposed to that direction. In theory, when the stars align, it could be fun for learners. But this time around, there’s just nothing doing. The tiny bits of swell we see – like 0.7 ft, 1 ft, even 3 ft on Tuesday morning July 21 – are all accompanied by cross-onshore winds, sometimes fresh, and the wave energy is feeble (the strongest reading is 57, still weak). The period is all over the place, but with those sizes and wind directions, it’s a waste of time. Even the few moments with a long-period swell (15–19 seconds) don’t help because the wind messes it up and the swell heights are barely a ripple.

Water temperature? No anomaly data given, so I can’t tell you if it’s warmer or colder than usual. But honestly, it doesn’t matter when there’s no surf.

If you’re desperate for a paddle, maybe a shortboard session on a knee-high day with a bit of cross-shore breeze? But I wouldn’t bother. The wind is mostly cross-on or onshore, often moderate to strong, and there’s even thunderstorm risk many days. This setup looks more interesting for kite surfing than paddle surfing – the consistent wind and chop might get a kite up, but for a surfboard? No.

Stay patient, folks. It tends not to stay this poor for long in this area, and forecasts can change. But for now, leave the board at home.

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.
