Water temperature in the Andaman Sea

The island of Phuket is bathed by the waters of the Andaman Sea, which is a part of the Indian Ocean. The sea is deep and can be somewhat unpredictable. The temperature of the Andaman Sea remains above +25°C throughout the year.

Spring

The warmest sea temperatures are experienced between March and May, during the tropical summer. During these months, the Andaman Sea around Phuket reaches its peak temperature of +35°C.

March and April are generally calm months, but the air becomes warmer. April is the hottest month in Phuket. Towards the latter half of May, the rainy season starts, the sea becomes rough, and it can be unsafe for inexperienced swimmers. It's worth noting that Phang Nga Bay in the Andaman Sea remains relatively calm even during these turbulent periods. This is something to consider when planning your vacation in Phuket.

Summer

In May, June, and July, Phuket becomes a haven for surfers. Strong sea currents, occasional storms, and winds are not conducive to leisurely swims in the sea. Storms typically occur in the afternoon or at night. Once the storm passes, the weather is usually sunny, hot, and dry.

Autumn

September can be a challenging period for tourists. Phuket's beaches are often marked with warnings for high winds and rough seas during this month. However, September is quite appealing to avid surfers. This is when traditional international surfing competitions take place in Kata Bay. It's worth noting that the reduced safety of sea bathing in September often leads to lower rental prices at the resort.

Winter

The prime time for sea bathing falls between January and February. During this period, humidity levels are lower, the weather is calm with little wind, and the tranquil Andaman Sea offers perfect conditions for swimming and leisurely beach activities. The water temperature in the Andaman Sea ranges from +28°C to +30°C.

Whatever your preferred sea activities may be, Phuket is waiting for you!
