Which of the following factors is crucial to monitor in marine weather forecasts?

Monitoring wave height and wind speed is crucial in marine weather forecasts because both of these factors directly impact the safety and performance of sailing activities. Wave height provides insight into the possible roughness of the sea, which affects how vessels handle on the water. Higher waves can lead to a greater risk of capsizing and may also complicate navigation.

Wind speed is equally important as it influences the sailing conditions. For instance, strong winds can create hazardous situations for small vessels, while moderate winds are typically ideal for sailing. Additionally, wind speed affects the formation of waves and their height, creating a correlation between these two factors.

Keeping an eye on both wave height and wind speed ensures sailors can prepare accordingly, making informed decisions about when to set sail, how to adjust their sails, and what safety measures to implement. Thus, understanding these factors is vital for ensuring a safe and enjoyable experience on the water.
