As Alabama benefits from a year-round, warm climate, October is still relatively mild. According to the Southeast Regional Climate Center, the average temperature for October is 64.1 degrees, with a maximum high of 74 degrees and a minimum low of around 57.6 degrees.
Precipitation is a constant feature of the Alabama climate but it does tend to be higher in the southern half of the state than in the north. Records from the Southeast Regional Climate Center indicate that the average level of precipitation in October is 2.92 inches. The lowest recorded precipitation level is 0.04 inches while the highest on record is 9.4 inches.
As Alabama has a subtropical climate, it remains humid throughout the year. The average percentage of relative humidity varies depending on location in Alabama. In the northern city of Huntsville, for example, it is around 63 percent while further south, in Birmingham, relative humidity is slightly lower at 61 percent. The maximum percentage of relative humidity for both cities in October, however, is 88.
October can also bring severe weather to Alabama. Hurricane season, for example, extends from May to October, with outbreaks peaking in September. Hurricane Opal, for instance, devastated the Gulf Shore area in October 1995. Another weather hazard, tornadoes, are less likely to be experienced in October as the most common months are March, April and November but they can occur at any point during the year.
