Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.
Water temperature data for this location is gathered from various sources, including buoys and satellite sea and ocean surface maps provided by the NOAA agency. We also incorporate data from local authorities in each specific location worldwide to ensure more accurate temperature readings.

Swimming Conditions
Swimming at Kata is popular for visitors seeking a traditional beach holiday, with a broad sandy shoreline and generally accessible entry into the ocean. In the dry season the bay usually has gentle, manageable waves ideal for casual swimmers and families, while the monsoon season brings larger surf and stronger currents that attract beginner and intermediate surfers but require more caution for swimmers. Lifeguards are often on duty in the busier periods and swimmers are advised to heed flags and local guidance, especially when rip currents develop. Beyond beach swimming, there are opportunities for snorkeling near rocky points, short boat trips to clearer spots, and plentiful resort pools for those preferring calmer water. Overall, the consistently warm sea temperatures support enjoyable water-based recreation throughout most months.
