Annual profiles of temperature, precipitation, humidity, wind, and daylight duration
These monthly climate averages for Olongapo Naval Base Perimeter National Park are based on 1991 to 2020 NASA POWER data for a representative coordinate at 87.8 meters elevation. Measurements provide a stable view of long-term atmospheric patterns, including daily temperature fluctuations and average precipitation rates. Values reflect climatological normals rather than current weather conditions or short-term forecasts for the broader landscape.
