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 opportunities around Pattaya are varied, from the urban sands of Pattaya Beach and the longer stretch of Jomtien Beach to quieter stretches in Naklua and the clearer waters off nearby Koh Larn (Coral Island). The Gulf is fairly sheltered, so currents are usually mild and beaches are shallow close to shore, making them suitable for families and casual swimmers; however, visibility and comfort can decline during the rainy season and occasional jellyfish or seaweed can affect conditions. Major beaches typically have lifeguards and rental facilities for snorkeling, diving trips, and other water sports, and many visitors find the best balance of calm sea and good visibility between November and May. Always heed local safety flags and boat traffic when choosing where and when to swim.
