a dry anchor means fair weather.
a wet anchor means it's raining.
a dusty anchor means a dust storm.
a swaying anchor means it's windy.
a shadow under the anchor means it's sunny.
a white anchor means it's snowing.
if the anchor is jumping up and down, expect rough seas.
if the anchor is under water it's likely that you are not underway.
