Snorkeling Calculator

Snorkeling Factors Explained

• Snorkeling Depth: Shallow snorkel dives (usually under 10 ft) are safe for most, but air and buoyancy vary slightly with depth.
• Duration: Time spent actively snorkeling, affecting calorie burn and exposure risk.
• Water Temperature: Ideal is 70–85°F. Cold water (<70°F) may require a wetsuit and increases calorie burn and fatigue.
• Activity Level: Impacts oxygen usage and calorie consumption. More movement = more air and calories used.
• Safety Score: Based on NOAA and Coast Guard swim safety: considers exposure time, thermal conditions, exertion, and depth.
