clouds in the sky
boats in the water
boats in the harbor
The sky is cloudy
The sky is overcast
The sky is grey
The sky is threatening
The sky is gloomy
The sky is heavy
The sky is sunless
The sky is hazy
The sky is precarious 
The sky is dismal
harbor full of boats
gray cloudy clouds above
there are many boats docked in the small harbor and several piers, under a cloudy grey sky
