Long-term representative point measurements for temperature, precipitation, wind, and daylight cycles
Examine the twelve-month climate profile for Catanduanes Watershed Forest Reserve based on representative NASA POWER records collected between 1991 and 2020. This data details consistent monthly averages for temperature, precipitation depth, relative humidity, wind velocity, and daylight duration at a specific reference elevation of 64.45 meters. Understanding these long-term trends provides a factual foundation for regional climate patterns without relying on current forecasts or local weather variability.

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.
