What should mariners check in addition to navigation charts for comprehensive safety?

In order to ensure comprehensive safety while navigating, mariners must be aware of current weather conditions. Understanding the weather is crucial because it can significantly affect visibility, wind strength, wave height, and overall sea conditions. Mariners need to know if there are any storms, fog, or changes in tides that could impact their route or safety during a voyage.

While local fishing reports, nearby landmarks, and a harbor's history may offer valuable insights, they do not address the immediate and dynamic hazards presented by weather. Weather conditions can change rapidly, making it essential for mariners to be informed on the latest forecasts and prevailing conditions to make timely and safe navigation decisions. This awareness helps avoid potential dangers such as storms or rough seas, ultimately enhancing the safety of the vessel and crew.
