What factors affect a scuba diving trip that need attention?

Weather in Phu Quoc: Rainy season and dry season

Weather in Phu Quoc

Phu Quoc has two distinct seasons: dry season (from October to April) and rainy season (from May to September).

• The dry season is the ideal time for scuba diving, when the weather is sunny, the sea is calm, and there are few clouds. During this period, the Phu Quoc sea is crystal clear, creating ideal conditions for you to admire coral reefs and the colorful world of marine life.
• The rainy season often comes with heavy rain, strong winds and rough seas, affecting underwater visibility, and diving safety. If you dive during the rainy season, large waves can reduce water clarity, making diving more difficult.

Water temperature and underwater visibility

Water temperature and underwater visibility

• Seawater temperature in Phu Quoc ranges from 27-30°C all year round, which is very comfortable for diving activities. However, the dry season often has more stable water temperatures, making you feel more comfortable when diving underwater for extended periods .
• Underwater visibility (water clarity) is an important factor determining the quality of your diving trip. In the dry season, visibility can reach 15-30 meters, ideal for viewing coral and fish. Meanwhile, the rainy season can reduce visibility to only 5-10 meters due to the silt and mud from the rain swept into the sea.
