Twelve-month average data for temperature, precipitation, humidity, wind, and daylight cycles
Analysis of the long-term atmospheric patterns for the Subic Watershed Forest Reserve based on NASA POWER measurements collected between 1991 and 2020. This profile presents representative monthly averages for temperature, precipitation, humidity, wind speed, and daylight hours at a fixed coordinate in Bataan. These figures provide a historical climate perspective rather than current weather observations, reflecting standard fluctuations throughout the year at an elevation of 87.8 meters.
Analyzing twelve-month thermal ranges and average daily precipitation patterns for Bataan protected terrain.
Analyze average temperature bounds, daily precipitation rates, humidity, wind speed, and calculated daylight across the calendar year.

See two months side by side and how much they differ. Both use the same 1991–2020 climate normals and NASA POWER data point as the table above, so they show typical conditions, not a forecast.
