What could be an indication of dangerous weather conditions while boating?

The indication of dangerous weather conditions while boating is marked by the presence of dark clouds and an increasing wind speed. Dark clouds often signify an approaching storm or a significant change in weather, which can lead to rough conditions on the water. Increasing wind speed can exacerbate the situation by creating larger waves and more turbulent waters, making navigation hazardous.

In contrast, clear skies and moderate winds typically suggest stable weather conditions that are safe for boating. Similarly, cool temperatures combined with sunny weather generally indicate pleasant boating conditions, as do low humidity and calm waters. These scenarios do not present immediate risks, whereas dark clouds and strong winds are clear signals of impending bad weather that boaters should take seriously.
