What the Counts Mean

Each count is a daily temperature record in that calendar month: a daily maximum or daily minimum that went past the earlier record at that station for the same day of the year. Record highs combine the daily maximum and the daily minimum.

Months differ in length, so a month with more days has more chances for a record. The counts are not adjusted for that. The latest 30 years are 1996 to 2025. The two spans come from different numbers of stations and years, so compare the shape across months and not the totals.
