July was unusually cool here


First Posted: 8/4/2009

No 90-degree days at all. Temperatures averaging only 71.5 degrees. That might seem typical for September but not July, when Mount Airy experienced an abnormally cool month.
The highest point reached by the mercury during Julys 31 days was only 89 degrees, logged on both July 17 and 26 at the citys F.G. Doggett Water Plant, this areas official weather-monitoring station. On the other end of the scale, the monthly low of 53 was recorded on both July 4 and 5.
Normally, at least several 90-degree readings and sometimes temperatures exceeding 100 can be expected during what is traditionally the hottest month of the year.
However, the cooling trend resulted in an average temperature last month of 71.5 degrees, well under the usual monthly average of 75.8 degrees.
Wet Trend Continues
Also during July, this area maintained a trend of above-average rainfall that began in the spring. Last month, precipitation totaled 6.67 inches nearly 2 inches above the 4.76 that are normal for the month.
Measurable rainfall occurred here on 18 of Julys 31 days, the largest amount 2.02 inches coming on July 12.
Julys totals added to a precipitation surplus established earlier in the year. Through last month, 35.84 inches had been received in Mount Airy, compared to the average of 27.37. That is 8.47 inches, or 31 percent, above normal for the year.
Fog was reported at the water plant on 12 days last month.
Weather records have been kept in Mount Airy since 1924.
