What is a common sign that the weather may change for the worse?

A sudden drop in temperature is a well-known indicator that weather conditions may be changing. When temperatures drop, it can signal the approach of a cold front or storm system, which often brings adverse weather such as rain, wind, or thunderstorms. This phenomenon is a critical observation for boaters, as it can affect safety and visibility on the water.

In contrast, bright blue skies typically indicate stable and clear weather, making them a less reliable sign for impending changes. An increased number of boats on the water does not provide information about the weather; in fact, it may reflect good weather conditions, encouraging more people to go boating. Finally, while birds flying low could suggest that they are seeking shelter from bad weather, this sign is less definitive compared to a noticeable drop in temperature regarding an impending change in weather conditions. Understanding these signs can aid boaters in making informed decisions while out on the water.
