How we compare prices

Regular gasoline only. We compare the region average today with its average yesterday and on the same date last month. Each average uses the available stations at that time, with prices no more than 36 hours old. The mix of stations and payment conditions can change, so this is an indicative region trend.

Yesterday: Oct 21, 2026: $6.113/gal, 677 locations. Last month: Sep 22, 2026: $6.332/gal, 6 locations. Cutoffs use the same local time in California; a shorter month uses its last day. Monthly comparisons need at least 3 stations on each date; daily comparisons need 12. Past averages are reconstructed from recorded observations.
