Number of days per month with maximum temperature greater than or equal to 90.0° F

The number of days in Sacramento with days at or above 90.0° F. has increased over the last 123 years. Prior to 1926, there were no days above 90 degrees in the month of April, but since then, April usually sees a few days of 90.0°+ temperatures. As would be expected, July and August see the most days with temperatures over 90.0°. In the late 19th and early 20th century there were often summers where Sacramento would see less than 20 days of temperatures over 90.0° in the months of July and August. Yet since the middle of the 20th century, it’s rare to see a July or August with less than 20 days per month with temperatures over 90.0°. Explore the chart below to see how many days per month in a given year reported maximum temperatures higher than 90.0° F.
