PORTLAND, Ore. (KOIN) -- Sunrises are getting later and sunsets earlier across the Pacific Northwest and that trend continues during the month of September.

Portland will lose a total of 89 minutes of daylight during the month of September. This decreasing light is what helps cool Portland area temperatures. The shorter days will also help start the color changing process in the trees of Oregon and Washington.

October is the month that loses the greatest amount of daylight with a decrease in 91 minutes of sunshine.

The amount of daylight seen around 8 p.m. will start looking a lot darker over the next two weeks as Portland area sunsets keep getting earlier.
