When the sun is setting and the sky in the west presents a color of
whitish yellow or radiates out at a great height, rain can be looked for
during the next night or day. Gaudy colors where clouds are definitely
outlined indicate probably wind and rain.
Before setting, if the sun looks diffused and the color is a brilliant
white, this forecasts storms. When the sun sets in a slightly purple sky
and the color at the zenith is a bright blue, this indicates fine
weather. A red sunset generally indicates good weather, whereas a ruddy
or misty sunset indicates bad weather.
