July 2011 will be remembered as a very hot and humid month when even the nighttime temperatures remained high. With such warm temperatures and below normal rainfall, it became necessary to water lawns and gardens to keep them from burning or drying up.
The average high temperature was 83.4 degrees, and the average low was 58.5 degrees giving us an average of 70.9 degrees, 2.3 degrees above normal and the 7th warmest on record. The warmest July average was 72 degrees recorded in both 1987 and 1988. The coolest July was 65.1 degrees recorded in 1992. Any year when the average July temperature here is above 70 degrees can be considered to be a hot one. There have been only eight years in the last 30 when July has averaged above 70 degrees. Nights here in the area are usually cool, but July 21 the temperature here in Riparius at 11 p.m. was 82 degrees, a bad night for sleeping. There were five days above 90 degrees compared to an average of 2.6 days. The highest temperature, 94 degrees, was recorded on the 21st and the lowest, 53 degrees, was recorded on the 15th and 16th.
Rainfall for the month was 2.37 inches, 0.6 inches below normal and not nearly enough to satisfy lawns and gardens. The greatest amount, 0.78 inches, fell on the 18th with measurable precipitation falling on only eight days.
The river reached its highest level, 4.43 feet, on the 18th and its lowest level, 2.70 feet, on the 1st.
