Visibility peaks at 30 meters during the dry season (December-April). The rainy season (May-November), which includes the typhoon season (July-November), can still offer great diving and may bring encounters with larger marine life. Dive centers prioritize safety and adjust schedules for weather.
Northern Vietnam is best from April to October. Central Vietnam, including Nha Trang and Hoi An, offers prime conditions from February to October. Southern Vietnam's seasons vary: Phu Quoc is best from November to May, while Con Dao shines from March to September. Always check local conditions before your dive.

Getting certified in Vietnam is popular, especially in Nha Trang, where calm, clear waters are ideal for learning. Dive centers offer courses from beginner to advanced levels. While "try diving" experiences are available, an Open Water certification is needed to explore most sites independently.

Safety First: Tips for an Unforgettable Dive
Your safety is paramount for an unforgettable dive. When you feel prepared, you can relax and enjoy Vietnam's incredible marine life.
Diving within your limits is the foundation of safety. If a dive seems beyond your skill level or conditions are challenging, choose an alternative site. Your professional guide is an invaluable resource for this.
Choose a reputable dive center that prioritizes safety and maintains its equipment. Ask about their emergency protocols; professional centers will welcome these questions.
Conduct a thorough equipment check with your buddy before every dive. Personal gear like a mask and fins can improve comfort. A 3mm wetsuit is generally sufficient for Vietnam's warm waters.
Respect marine life and the fragile ecosystem. Avoid touching corals or disturbing animals. Take only photos and leave only bubbles.
Beyond gear, pack eco-friendly sunscreen and any necessary seasickness remedies. A safety sausage (SMB) is a valuable tool for visibility.
Adhere to the 24-hour no-fly rule after your last dive to prevent decompression sickness. Plan your travel accordingly.
Stay hydrated by drinking plenty of water before and after dives to prevent fatigue and cramps.
