Fine: No rain or other precipitation (hail, snow, etc). The use of fine is generally avoided in excessively cloudy, windy, foggy or dusty conditions. In particular, note that fine means the absence of rain or other precipitation such as hail or snow--not 'good' or 'pleasant' weather.
Clear: Free from cloud, fog, mist or dust haze.
