This morning's reading of -1 broke the record for January 7th of +1 that was set in 2014. This morning we set a daily low temperature record at Dulles for the first time since the above one, which was more than six and a half years ago. Today's morning low of 49 beat the previous August 22nd record of 51, which was set in 1969 and equaled in 1976. FYI, on June 20, 2022 Dulles tied the June 20th low temperature record of 48 set in 2000, but failed to break that record. 3 2 Link to comment Share on other sites More sharing options...

Summer record lows are the best record lows. 5 Link to comment Share on other sites More sharing options...

mdhokie Posted October 31 Share Posted October 31 Gut feeling is the lows are warmer than normal. I dont remember a ton of super hot days but it feels like it never really cools off at night. Link to comment Share on other sites More sharing options...

I dont remember a ton of super hot days but it feels like it never really cools off at night. For October? For the airports and city, maybe (quick in-precise check, looks like DCA had 14 nights above avg.) But we've had a couple stretches of multiple <40 degree nights. Here, one of those was 5 straight nights of temps in the 30s. 100% sure other places fared better. I think that's not too shabby for October around here.... 1 Link to comment Share on other sites More sharing options...

Here, one of those was 5 straight nights of temps in the 30s. 100% sure other places fared better. I think that's not too shabby for October around here.... Your point is well-taken. I just did an analysis that shows that the DCA October 2024 average maximum of 73.0 (3.6 degrees above the 1991-2020 normal) tied for the 8th warmest in DC history. On the other hand, the DCA October 2024 average minimum of 53.0 (0.8 degrees above the 1991-2020 normal) tied for the 27th warmest in DC history. So, in contrast to many recent months over many recent years, the average maximum was much further above the recent normal than the average minimum was. As a personal observation, when you couple the DCA October 2024 maximum range of 60 to 83 degrees and the minimum range of 44 to 67 degrees with only 1.48 inches of precipitation (all of which fell on the first two days of the month), a case can be made that October 2024 was the best month in DC history for sunny and pleasant weather. 1 Link to comment Share on other sites More sharing options...
RodneyS Posted November 7 Share Posted November 7 Today reached 84 at DCA, the warmest temperature ever in DC from November 5th to February 24th. February 25, 1930 also reached 84, and the first day in a calendar year to exceed that was March 8, 2000, which reached 85. 5 Link to comment Share on other sites More sharing options...

January-October 2024 averaged 64.5 at DCA, 2nd warmest in DC history, behind 2012 (64.7). November 2024 at DCA has for sure broken the record high average November DC temperature of 54.8 degrees, which was set in 2001. DCA finished at 55.2, which resulted in a record high January-November average of 63.6, beating the previous 11-month record of 63.1, which was set in 2012. That puts DCA on course to break the previous DC calendar year record of 61.6, also set in 2012. All that is needed is for DCA to average 39.0 degrees or higher in December -- 39.0 would be 2.7 degrees below the 1991-2020 normal. Note: Edited on December 1st because the final November 2024 DCA temperature average was 55.2, rather than 55.1 3 Link to comment Share on other sites More sharing options...
