fall here! Here are some important dates for the upcoming season

It’s hard to believe that summer 2022 is already over. The summer season ended with a total of 38 days above 90 degrees, well below the 40-day average that the metropolitan area typically sees each year. In fact, the last 90 degrees was on September 4th, which is associated with 2020 with the closest day we saw the last 90 degrees in the past decade. We also ended up about an inch above normal precipitation with less than thirteen inches of rain falling this summer, more than half of which fell during July. Our highest temperature was 99 degrees, making it the sixth summer in a row without 100 degrees a day in Washington, D.C., although humidity values ​​remained high for most of the summer.

Fall officially begins Thursday night after 9 p.m. ET, and fall will start to feel fast. Temperatures are expected to drop Thursday night due to winds that may reach 30-40 miles per hour during the evening hours. Friday may be the first day since the second half of May that the temperature in the capital fails to exceed 70 degrees Celsius in the afternoon. By Saturday morning, with the winds calming under a clear sky, and with a very dry Canadian air mass in place, most of the area will be heading into the 40s overnight, while DC heads into the lower 50s, its coldest morning in several months.

As the new season arrives, here are some fun metrological dates for the upcoming season!

September 22 – 9:04 pm – autumnal equinox! Or the official start of autumn in the northern hemisphere. This is the time when the sun rises directly at the equator, and the northern and southern hemispheres get the same amount of rays.

September 25 – sunset – The last night this year the sun sets at 7 p.m. here in the county.

October 9 – Hunters Full Moon – The first full moon in the fall! This moon name goes back to Native American folklore, and it was given because it was at this time when tribes gathered meat for the next long winter.

October 14 – sunset – The last night this year the sun sets before 6:30 p.m. here in the neighbourhood.

October 16 – a milestone in the capital’s temperature – The average high temperature drops below 70 degrees.

October 17-October 31 – fall foliage – Anticipate two-week window for the best viewing of fall foliage across the Mid-Atlantic and metropolitan area. Plan those paper peeping trips accordingly!

October 21 and 22 – meteor showers – Orionids are so called because the point they seem to come from lies in the constellation Orion, although they are often seen across a large expanse of sky. They are the largest meteor shower associated with the famous Halley’s Comet. While it can be seen between late September and November each year, this year it will peak between sunset on the twenty-first and sunrise on the twenty-second. A typical year brings about 23 meteors per hour.

October 23 – a milestone in the capital’s temperature – The average low temperature in the capital falls into the forties.

November 6 – Back! – We go back to standard time and get an extra hour of sleep the first weekend of November. Gain an hour of daylight in the morning, while wasting an hour in the evening.

November 8 – sunset – The last night this year the sun sets before 5pm here in the area.

November 8 – full moon and total lunar eclipse – The beaver moon, sometimes called the Frost Moon, is called because it came at a time of year when beavers were particularly active, and Native Americans and colonists would set traps to catch them before the swamps would freeze for the winter months. This year’s November full moon will come with an extra treat, a total lunar eclipse, although it can be hard to see in the metropolitan area. The moon will be low in the sky when completely swallowed by the Earth’s shadow (giving it a reddish hue) which is no more than 16 degrees above the horizon, and falls through the moonset at 6:49 p.m. The sun will also rise at 6:43 AM, which means the sky will be brighter by 6 AM. Space enthusiasts will want to wake up early and find an elevated viewing position to view the final 2022 lunar eclipse.

November 12 – milestone in DC temperature – The average high temperature in the capital drops below 60 degrees.

17/18 November – Leonid Meteor shower – It is associated with Comet Temple-Tuttle, taking their names as they appear to have originated from the constellation Leo. During their peak between sunset on the 17th and sunrise on the 18th of November, about 15-19 meteors per hour are expected. Known as a “meteor storm,” meteor showers are known for very impressive shower rates of over 1,000 per hour, every 33 years or so. The last meteor storm Leonid occurred in 2002, which means we can likely wait until the mid-2030s for the storm to return to our skies.

November 23 – a milestone in the capital’s temperature – The average low temperature in the capital falls into the 30s.

November 31 – Hurricane season ends – The official end of the 2022 Atlantic hurricane season

December 7 – cold full moon – The Native American names for the full moon in December are the cold moon or the long night moon. The Cold Moon got its name because December is the month when it really gets cold, although our average coldest temperatures are in January. The Long Night Moon got its name because the December full moon occurs near the solstice, the longest night of the year.

December 13 – milestone in DC temperature – The average high temperature in the capital drops below 50 degrees.

December 21 – Autumn ends and winter begins Winter officially begins at 4:47 pm on Wednesday, December 21!
