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.
Annual Water Temperature Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Phuket, an island province in southern Thailand, offers warm tropical seas year-round, with surface water temperatures typically ranging from 27°C to 31°C. During the coolest months, usually December to February, sea temperatures hover around 27°C to 29°C, providing comfortable conditions for most swimmers. The pre-monsoon spring and early summer months, March to May, see temperatures rise to about 29°C to 31°C, making the water especially pleasant for long swims and snorkeling. The southwest monsoon season, from June to October, brings more rainfall and some onshore wind and swell, but water temperatures generally remain mild at 28°C to 30°C. In November the seas begin to cool slightly after the monsoon, settling back toward the 27°C to 29°C range. Visibility and currents can vary with seasonal weather, yet thermal comfort is consistently high compared with temperate destinations.

Swimming Conditions
Swimming in Phuket suits many visitors, from calm sheltered bays to beaches with waves for recreational surfing. Sheltered west coast beaches with gentle shore breaks usually offer safe, shallow water for families and casual swimmers when conditions are calm, and the warm sea encourages long periods in the water. Snorkeling off rock outcrops and nearby islands is rewarding when the 28°C to 31°C waters support coral and fish, though visibility falls after heavy rain. In the monsoon, stronger currents and rougher surf can make some beaches unsuitable for casual swimming, so follow lifeguards’ advice. Overall, Phuket’s consistently warm sea temperatures make it an attractive choice for swimming, snorkeling and beach relaxation nearly year-round.
