Corrected entry: Kirk's birthday visit from McCoy in his personal quarters overlooking San Francisco's Golden Gate Bridge is soundtracked by an audible foghorn, though there's no fog. Atmospheric as though this may be, I know for a fact [as a resident of this place] that no foghorn will sound when there's no fog and the sky's full of stars.

Correction: This film is set in the 23rd century. There is no way to know it was a fog horn. It could merely be a similar sounding alert for something else. With the technology available, fog would hardly impair the ability to detect what is around them.
