Detailed twelve-month profiles of temperature, precipitation, and wind speeds at the representative site.
Examine the long-term climate pattern of Lesvos Petrified Forest through consistent monthly averages measured from 1991 to 2020. These metrics provide a clear view of temperature trends, daily precipitation rates, relative humidity, wind velocity, and daylight duration at a representative coordinate. Use this structured data to analyze how atmospheric conditions fluctuate throughout the calendar year without the variability of short-term forecasts.
