Heavy rainfall across the western half of Georgia helped to keep daytime temperatures low, while nighttime temperatures were a little above normal throughout August.
Wet conditions early in the month caused problems for farmers trying to do field work, but the precipitation was generally good for most crops. Some hay production was limited until the end of the month when a dry spell allowed many forage producers to make their last hay cutting of the year. Despite the high humidity and rainfall, disease pressure has been low, but it increased by the end of August. Some irrigation was needed for crops in the eastern half of the state where drier conditions prevailed, but most crops were in good condition at the close of the growing season.
Given the low daytime temperatures and relatively high nighttime temperatures, average temperatures were near normal throughout the month.

The outlook for September shows that warmer and wetter conditions have a slightly increased chance of occurring. For the September through November period, climate predictions continue to lean toward near-normal temperatures based on a combination of the long-term rising temperature trend offset by cooling from the expected El Nino clouds and rain. Precipitation forecasts show an increased chance of above-normal rainfall this fall.
