Long term monthly averages for temperature, precipitation, and wind speeds
Review established climate normals for Roosevelt Protected Landscape in Central Luzon, covering the 1991 to 2020 period based on a representative coordinate. This profile tracks twelve months of average minimum and maximum temperatures, daily precipitation rates, relative humidity, wind speed, and daylight hours to illustrate annual atmospheric variations.

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.
