Even with temperatures in Flagstaff mercifully coming down closer to normal following a record-breaking March, the city surpassed the hottest first four months in history.
April’s average high temperature finished at 60.3 degrees, well behind March’s 66.9 degrees, and the month recorded no days that surpassed the 70-degree mark. In fact, April’s high of 69 degrees on the 8th, 19th and 20th all tied for the 14th warmest day of 2026 behind 12 days in March and one in February. The last time April’s warmest temperature failed to surpass March was in 2017, when April peaked at 70 degrees behind March’s 71 degrees.
