May brings drought in north Georgia, heavy rain in Savannah By Pam Knox

In May 2016, most of Georgia suffered from a lack of rainfall, while record-setting rain fell in Savannah, Georgia. Drought conditions expanded statewide, and severe drought returned to the northwest corner of Georgia by the end of last month.

In the dry areas of the state, pastures, livestock and summer row crops suffered due to this lack of rainfall. Some farmers were waiting for rain to finish planting their dryland crops, and many corn farmers relied on irrigation to keep their crops healthy during the month.

In central Georgia and the coast, where wet conditions occurred, some fungal diseases were observed.

According to National Weather Service stations, the highest monthly total rainfall was 8.99 inches in Savannah, 6.01 inches above normal. The lowest monthly total rainfall was 0.78 inches in Albany, Georgia, 1.91 inches below normal.

  • Atlanta received 1.25 inches of rainfall, 2.42 inches below normal.
  • Athens, Georgia, received 2.49 inches, 0.51 inches below normal.
  • Columbus, Georgia, received 2.51 inches, 0.68 inches below normal.
  • Macon, Georgia, received 1.96 inches, 0.76 inches below normal.
  • Augusta, Georgia, received 5.71 inches, 3.06 inches above normal.
  • Alma, Georgia, received 3.34 inches, 0.87 inches above normal.
  • Brunswick, Georgia, received 1.68 inches, 0.18 inches below normal.
  • Valdosta, Georgia, received 3.45 inches, 0.92 inches above normal.

Savannah received most of its monthly rainfall in the middle of the month. The Savannah weather service station set a new daily record on May 17, recording 2.29 inches of rain, breaking the old record of 1.62 inches set in 1980. Augusta broke a daily record on May 29, receiving 2.28 inches, breaking the old record of 2.08 inches set in 2001.

The highest single-day rainfall recorded by Community Collaborative Rain, Hail and Snow Network volunteers was a total of 8.65 inches, recorded south of Savannah in Chatham County, Georgia, on the morning of May 18. This total was followed by 7.59 inches, which was recorded on Skidaway Island, also in Chatham County.

Many other stations in that area received more than 5 inches of rain on May 18. The highest monthly rainfall totals were 14.34 inches, recorded in Newington, Georgia, in Screven County; 12.7 inches recorded near Marlow, Georgia, in Effingham County; and 10.15 inches recorded by a Savannah observer with the highest daily amount.

On the other end of the spectrum, one network volunteer in southwest Georgia's Grady County reported that he had received only 0.73 inches for the whole month.

Temperatures at most locations were near normal in May.

  • In Atlanta, the monthly average temperature was 71.1 degrees Fahrenheit, 1.0 degrees above normal.
  • Athens: 70.3 degrees F, 0.3 degrees above normal.
  • Columbus: 72.5 degrees F, 0.5 degrees below normal.
  • Macon: 71.8 degrees F, 0.1 degrees below normal.
  • Savannah: 74.0 degrees F, 0.7 degrees above normal.
  • Brunswick: 74.9 degrees F, 0.4 degrees above normal.
  • Alma: 73.0 degrees F, 0.7 degrees below normal.
  • Augusta: 70.7 degrees F, 0.4 degrees below normal.
  • Albany: 74.5 degrees F, 0 degrees above normal.
  • Valdosta: 73.9 degrees F, 0.1 degrees above normal.
  • Rome, Georgia: 69.0 degrees F, 0.8 degrees above normal.

Brunswick tied a 1973 record low temperature of 50 degrees F on May 6, and tied a 2012 record for high nighttime low temperature with 73 degrees F on May 2.

Climatologists are predicting that the summer will bring warmer-than-normal conditions. Dry conditions or drought may continue in northwest Georgia in June, although there are no trends determined for the summer period overall.

Cooler-than-normal water in the equatorial Pacific Ocean means that El Nino is almost gone and neutral conditions should be declared before a likely swing to La Nina later in summer. The Atlantic tropical season began with the development of Tropical Storm Bonnie in late May, and activity is expected to be normal to above-average this year due to La Nina conditions.
