Ok, I am being unbalanced with D.C. climo of late. It’s a mindless task when bored, and I recently finished a compilation. Here’s a graph (to scale, if not clearly marked as such) of high and low temperatures by year in Washington, D.C. The change in highs has been quite minor though the range is equally small. Lows, however have seemingly continually pressed upwards throughout recorded history.
The 81-2010 average for the highest temperature of the year was 98.8, with the long-term average coming in at 98.3. The 81-2010 average lowest temperature was 9.9, while long-term is 7.3.
This post is part of a Washington, D.C. climatology series, both on and off site, that will be maintained at semi regular intervals.
