Always research the best time to visit your chosen destination. Factors to consider include:

• Visibility conditions

• Water temperature

• Marine life migrations

• Monsoon or hurricane seasons

• Local holidays that might affect availability

Conservation Status

The health of dive sites can change rapidly. Before booking:

• Check recent reviews from other divers

Logistics and Budget

Beyond the diving itself, consider:
