Detailed atmospheric measurements for a representative coordinate from 1991 to 2020
Annual climate profiles for Mount Arayat National Park provide long-term averages for temperature, precipitation, humidity, wind speed, and daylight duration. These records, derived from NASA POWER measurements at a representative point, offer a structured twelve-month view of atmospheric patterns. Data reflects historical climate averages to ensure consistent analysis rather than reflecting current daily weather conditions or site-specific forecasts across the entire protected area.
