FYI, I have discovered two other days where DCA also recorded an average temperature of 93.0. Those are July 6, 1999, with a maximum of 103 and a minimum of 83; and July 23, 2011, which was the same as yesterday -- maximum of 102 and a minimum of 84.

Today's DCA minimum of 84 tied the DC record high minimum set on July 16, 1983 and duplicated on both July 23rd and 24th 2011. Moreover, today's combination of a maximum of 102 and a minimum of 84 resulted in a daily average temperature of 93.0 -- second highest behind July 7, 2012. That day at DCA saw a maximum of 105 and a minimum of 82, for an average of 93.5.

According to my records, 2026 is actually the 12th driest first half in DC history, but you are correct that the first half of 2023 was even drier, at only 12.32 inches (5th driest). Interestingly, the driest and wettest first halves in DC history each occurred in the 19th century: Driest: 1872 with 10.49 inches Wettest: 1886 with 35.80 inches It should also be noted that calendar years 2023-2025 were each drier than normal, averaging only 36.27 inches annually. However, during 2018-2022 DCA averaged 50.71 inches -- the wettest five consecutive calendar years in DC history.
