Longer nights as we quickly lose daylight

We are losing daylight every day. Here's a breakdown of our longer nights and the duration of daylight in the coming days.

The time of year is approaching when it's dark outside when you leave for work and arrive home in the afternoon. The nights are quickly getting longer as darkness out weighs daylight, and we are quickly losing our daylight. Here's a breakdown of the details and what it means to our weather.

With a sunrise shortly after 7am and sunset at 6:42pm, D.C. has 11 hours and 33 minutes of daylight today, but that drops more than an hour to 10 hours and 20 minutes by this time next month. Compare that to our "shortest days," which are December 21st and 22nd when we have only 9 hours and 26 minutes of daylight.

Longer nights and shorter days in the fall generally leads to cool mornings but comfortable, and sometimes warm afternoons. For example, lows this morning are mostly in the 40s across the abc7 viewing area, but afternoon highs will reach into the lower 70s. This is about a 30 degree temperature change, so you'll want a light jacket in the morning then short sleeves into the afternoon. As for the weekend, it'll be slightly warmer but with a big temperature gap as morning lows drop into the 50s and afternoon highs climb into the lower 80s by Sunday.
