Review long-term averages for temperature, precipitation, humidity, and wind speed patterns.
Annual atmospheric patterns for Pulai River reveal monthly trends in temperature, precipitation, humidity, wind, and daylight based on NASA POWER data from 1991 to 2020. These measurements represent climatological norms at a fixed coordinate within the Johor nature reserve, providing a foundational baseline for regional geography. Data focuses on twelve-month variations in climatic variables rather than current weather conditions or local site-specific extremes.
