Sierra de San Juan Biosphere Reserve: Monthly Climate Normals and Atmospheric Data Profiles

Trace the seasonal progression of the Sierra de San Juan Biosphere Reserve through a structured breakdown of long-term atmospheric patterns. Measurements include monthly averages for minimum, mean, and maximum temperatures; daily precipitation rates; relative humidity; wind speed; and daylight hours. These data points represent climatological norms recorded between 1991 and 2020 at a fixed representative coordinate within the reserve.
