Review annual patterns of relative humidity, wind speed, and daylight hours based on representative coordinates
Detailed twelve month climate normals provide a representative profile of the atmospheric conditions at Angat Watershed Forest Reserve. Data reflects long term averages for mean, minimum, and maximum temperatures alongside daily precipitation rates, humidity, wind speed, and daylight duration. Measurements span the 1991 to 2020 climatology period to characterize the regional patterns of this nature reserve in Bulacan.
