Columbus is on track to have its second-coolest July on record, according to the National Weather Service.
It's no arctic blast, but lower temperatures are affecting what we do, from turning off the air conditioning to staying away from the neighborhood pool.
This month's average, 70.5 degrees, is more than 4 degrees lower than usual. The last time it was that cool was in 1971.
The city's coldest July on record, in 1891, had an average temperature of 70 degrees.
These lower temperatures could lead to lower energy bills for people who opt to open the windows rather than blast the AC.
American Electric Power compiles the number of "cooling degree days," a measure that forecasts the energy demand for air conditioning each month.
AEP said there has been a 34 percent decrease in cooling degree days this month compared with July last year.
"The weather may be playing an important role in that, and the economy may be, too," said AEP.
The summer chill is also keeping people from dipping their toes in the water.
John Gannon, manager at the Columbus Zoo and Aquarium's Zoombezi Bay water park, said attendance dropped by about 15 percent from last summer, its first year
The park has held "dive-in movies" at night to draw people into the heated pool.
"We still have some time to make most of that up if we would ever get back to a normal summer," Gannon said.
Amanda Besluiter, a manager at Northwest Swim Club on Bethel Road, said the club's attendance is down by about a third because of the weather.
"We've definitely had fewer people come by," she said.
Why does our late July feel like early June? Weather experts say a long area of low-atmospheric pressure along the East Coast is lowering temperatures.
"As for what's happening right now, it's atypical for this time of year, but it's happened before," said Nick Greenawalt, a meteorologist for the National Weather Service.
Rainfall in central Ohio is more than 4 inches below normal for the year and about 1.5 inches below normal for July, causing some lawns to start to brown.
It did rain yesterday, with the rainfall measuring 0.39 inches as of 9 p.m.
The cooler weather should help the lawns, said David Gardner, an associate professor of horticulture and crop management at Ohio State University.
Gardner said the grass in this part of the country tends to go dormant when temperatures exceed 80 degrees.
People should water their grass with an inch of water each week, Gardner said. The best time to water is early morning, so less moisture is lost to evaporation.
"If people are careful about their irrigation management, they should be able to keep the grass
