Average Fall Sunshine by USA State

The tables below pull together numbers on the amount of sunshine that each US state usually has during fall. There's information by state on the season's averages for percent, hours and days of sun.

The % Sun number measures the percentage of time between sunrise and sunset that sunshine reaches the ground. Total Hours is the average number of sunny hours a place normally has in autumn. Clear Days is the average number of days in fall when cloud covers at most 30 percent of the sky during daylight hours.

All of the numbers are averages of several decades of weather measurements. The autumn totals are based on data for the months of September, October and November.

Since so few weather stations measure sunshine, meaningful state-wide averages aren't available. Instead, the tables list a place for each state that represents the state's typical amount of sunshine.
