PORTLAND PRESS HERALD • October 31, 2024
Temperatures in Greater Portland hit 77 degrees Thursday, an unusual – but not unheard of – Halloween heatwave. Halloween 1946 saw a high of 80 degrees in Portland, and that record has held since. The average low Halloween temperature in Portland between 1981 and 2010 is 34.8 and the average high is 53.4 degrees. While Portland came just under its record, Augusta “climatologically shattered” its previous record high Thursday. There, the day’s high of 77 degrees was well above the previous record of 69 degrees set in 1956.
