Rainy July 2013 - Stats and Information

GIS rainfall map for July 2013 created from a combination of observing sites across the area. Map via Parks Camp.

July 2013 was an extremely wet month for the local area, which includes southeast Alabama, southwest Georgia, and the Florida Panhandle and Big Bend. Widespread totals of 10 to 20 inches of rain were common, with isolated amounts up to nearly 30 inches. It was also a wet month in general for much of the southeast United States.

Measurable rainfall (at least 0.01") occurred on 25 of 31 July days (81%) at the Tallahassee Airport, with rain being reported (at least a trace amount) on all but one July day (97%). For the months of July and August together - 17 days at Tallahassee had at least one half inch of rain, which is a record. The period of record at Tallahassee stretches back to 1896.

July 2013 was the wettest July on record for the state of Florida, with an average rainfall of 12.38 inches (4.91" above average). It was also the fourth wettest July on record for the states of Alabama and Georgia.

Geneva, Alabama, which was affected by heavy rainfall and flooding in February, ended the month of July with a year-to-date rainfall total of 62.70 inches, which was a record. That total exceeded the previous record from 1991 by 4.41 inches, and it exceeded the normal rainfall for January-July by a whopping 26.36 inches.

At official climate sites, rainfall departures from normal for just the month of July included: +15.35" at Cross City, +11.62" at Dothan, +7.79" at Tallahassee, +5.24" at Apalachicola, +2.74" at Valdosta and +2.17" at Albany.

The five highest rainfall totals that we received for July 2013 were in the western portion of our Florida panhandle counties - in the general vicinity of Panama City. They were, in order: 28.28" at Greenhead, 27.76" near Inlet Beach, 26.02" in Panama City (at Hwy 231 & East Ave.), 25.14" near Panama City Beach, and 24.96" at Lynn Haven.

The Lynn Haven, Florida observer site has had expected rainfall return periods computed for it that are available through the Hydrometeorological Design Studies Center. Lynn Haven had 24.96 inches of rain in July, which compares to around a 25-50 year expected return interval for a thirty day rainfall. However, 30-day rainfall in the Lynn Haven & Panama City area that is closer to 28-29 inches would be closer to a 100 year expected return interval, and such rainfall totals occurred in isolated instances during the month of July in those areas.
