Let's dive deep into Downtown Sac's record book, which goes back to 1877.

Of all days' high temps in the record book (N=53015)
▪️4.0% (n=2114) were ≥100°F
▪️0.9% (n=479) were ≥105°F
▪️0.06% (n=34) were ≥110°F

Downtown Sac's all-time record high is 114°F set in 1925.

This all-time record was most recently jeopardized last year Jul 10, 2021 with 113°F.
