The Lowdown
Alright, this is Rusty here, and I've got the outlook for your local stretch. Let's be straight with each other—this one's a tough read.
Right off the bat, I gotta tell you that for the next couple of weeks, the surf is looking pretty bleak around here. We've got a long, long stretch of flat, choppy, or just plain messy conditions. There are no real standouts, no days to circle on the calendar. The forecast goes out 16 days, and honestly, the first real action we might see is so small and weak it barely counts.
Looking at the whole period, it’s a lot of cross-onshore wind, and the swell energy is just not there. Most of the time the combined energy is either zero or hovering in the low double digits (like 21 or 25), which is weak. The water temp is sitting around 86°, which is about average for the time of year, so at least a dip will be warm.
Let’s walk through it day by day.
Starting on Tuesday, July 14th, the wind is a messy cross-onshore at 16 mph with a risk of thunderstorms. Surf is essentially flat. The same story holds for Wednesday, July 15th and Thursday, July 16th. On Thursday morning we actually see a tiny, glassy moment with a weak 0.3 ft swell from the SW, but it has a very long period of 16 seconds and only 10 units of energy. That period is long, but there’s no size to work with. It's nothing you'd paddle out for.
Friday, July 17th through Saturday, July 18th tease us with a tiny 0.7 ft swell from the WSW, but the wind is cross-onshore and choppy. It’s not surfable.
Sunday, July 19th is the most interesting day of the whole run, and that's not saying much. The swell bumps up to 3 ft in the morning and 4 ft in the afternoon, both from the west. The problem? The period is a very short, weak 5 seconds, and the wind is a strong cross-onshore at 16 mph. The combined energy for the afternoon peaks at 90, which is still in the weak range. It’s going to be choppy, lumpy, and honestly, this looks more like a day for kite surfing than trying to get a clean paddle wave at Kata Beach. It’s an exposed beach break, and with that wind and weak, short-period swell, it’ll be a washing machine. This break is also inconsistent and often crowded, but with conditions this poor, crowds won't be the issue.
From Monday, July 20th all the way through to Tuesday, July 28th, the forecast is filled with blanks. Zero swell and fresh cross-onshore winds. It’s just a dead zone. A few days out around Friday, July 25th, we see a tiny 0.7 ft WSW swell creep back in, but with 17-second period and fresh winds up to 19 mph, it’s useless.
The last few days, Monday, July 28th and Tuesday, July 29th, are the same story: small, weak, and blown out.
The call: There is no good surf on offer in this 16-day window. The only day that even hints at something is Sunday, July 19th, but it's a mess. You’re better off leaving the board at home and going for a swim. It’s a normal blank run for this area, so don’t lose hope—forecasts can change.
Stay salty,
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.
