Roosevelt Island is Beautiful in the Fall |
Washington,
D.C.’s warmest October temperature on record was 96 degrees (on October 5, 1941). However, this fall it hasn’t been 90 degrees
since September 9 when it was 94. In
fact, the warmest temperature this month in the Nation’s Capital was 79 degrees
on October 9. The coolest temperature so
far this month occurred on October 19 when the low fell to 37 degrees. However, temperatures fell to the upper 20s
the very same morning.
The warmest October on record in the Nation’s Capital was in 2007 when the average monthly temperature (combining daily highs and lows) was 67.1 degrees, compared to a monthly average of 59.5 degrees. The coolest October on record in the Nation’s Capital came in 1876 when the average temperature was 50.7 degrees. Modern weather observations in Washington, D.C. have been made at National Airport since it opened in 1941.

Meteorological fall runs from September 1 through November 30.
Meteorologists break up the seasons into equal three-month periods for
the ease of averaging climate data. This
fall got off to a torrid start in the Nation’s Capital, with seven of the first
ten days of September seeing high temperatures in the 90s. Although September was nearly four degrees
warmer than average in Washington, D.C., the pendulum has swung the other way
in October. So far this month, there
have been five days with highs in the 50s in the Nation’s Capital, which is
more characteristic of the second half of November. Through October 26, this month has been a
full degree cooler than average in Washington, D.C.
Last week,
Hurricane Patricia became the strongest hurricane on record in the Western
Hemisphere. That’s typical of an El Nino
year when conditions are favorable for more frequent and more intense
hurricanes in the Eastern Pacific Ocean.
The remnants of Hurricane Patricia will enhance the rainfall across the
Mid-Atlantic Region tonight and tomorrow.
However, no high winds or flooding rains are expected.
The
Mid-Atlantic Region has felt the impacts of former tropical storms and
hurricanes in October several times. In October
1995, the remnants of Hurricane Opal brought appreciable rainfall and a few
tornadoes to the Maryland suburbs of Washington, D.C. Just three years ago, the Mid-Atlantic Region
felt the frightening impact of Sandy. At
one point, Sandy was a major Category 3 hurricane while over the open ocean,
but weakened before coming ashore. The
DC Metro Region saw record rainfall from Sandy as 3.85” of rain fell on October
29, 2012. Fortunately, rainfall totals
like that aren’t expected from the remnants of Patricia.
