Alright folks, Rusty here, and we’re looking at a tough 16 days ahead for Kalim Beach. This is an exposed reef that needs a sweet SW swell and clean wind, but we’re just not catching a break.
The first few days offer absolutely nothing. We finally see a sliver of hope on Thursday, July 16th, with a marginal 4ft west swell in the morning. The wind is light and onshore, so it might look okay from the car park, but the energy is weak (238) and it’s a real question mark. After that, it’s back to poor, choppy, onshore conditions through the rest of the week.
Heading into the second week, the swell actually fills in—big time. From Monday, July 21st, through Thursday, July 24th, we’re looking at solid 8ft to 8ft west swell with real grunt (energy peaking at 887). But here’s the problem: it’s getting hammered by fresh onshore winds—25 to 30 mph WSW. The wave comment is "poor surf conditions" every single day. At that size (anything over 8ft is heavy), it’s expert territory, and with that wind, it’s gonna be a blown-out, lumpy mess. That setup screams kite-surfing more than paddle-surfing.
Kalim is an inconsistent spot, and this is a proper flat spell for quality waves. It’s a bummer, but it happens here. The water feels about normal for this time of year. Keep an eye on it, but don’t hold your breath. Rusty.

Information about the Kalim Beach Surf forecast
The above surf forecast table for Kalim Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kalim Beach can be found by selecting the local surf guide option on the grey menu. Our Kalim 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 (Kalim 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 Kalim 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.
Kalim Beach is 7 km (4 miles) from Kathu. If you plan a holiday in Phuket, look for hotels and other accommodation in Kathu. Kathu has rooms for a wide range of budgets as well as car hire and transport links.
