Seasonal Temperatures Won’t Tax Energy Through September

After cooler air passes across the Midwest this weekend, most of the U.S. will have seasonal temperatures that won’t tax energy demand for heating or cooling through the end of the month.

Seasonal weather is expected to dominate most of the Midwest, the South and the East Coast from Sept. 25 to Oct. 4, according to Matt Rogers, president of the Commodity Weather Group LLC in Bethesda, Maryland.

“The majority of models show a very demand-neutral pattern,” Rogers wrote in a note to clients. “This works against both late-season Southern cooling demand and early- season Northern heating demand.”

Temperature fluctuations outside normal levels have little impact on energy markets at this time of year. Energy traders and meteorologists use a base of 65 degrees Fahrenheit (18 Celsius) as the benchmark for when people won’t need heating or air conditioning to remain comfortable.

The normal average temperature in New York on Sept. 27 is 65, according to MDA EarthSat Weather in Gaithersburg, Maryland. It’s 61 in Boston, 67 in Washington, 70 in Atlanta, 62 in Chicago, 76 in Houston, 59 in Seattle and 71 in Burbank, California.
