A Hot Summer: 300 All-Time Records Broken


According this CNN article, 300 all-time heat records were broken in the US this past summer.

From June 1 through September 12, at least 356 all-time heat records from California to Maine from a subset of weather stations were tied or broken, according to a CNN analysis of National Oceanic and Atmospheric Administration data. CNN examined the highest maximum and minimum temperatures collected by weather stations across the country with at least 30 years of data.

Ahira Sanchez-Lugo, a climatologist at NOAA’s National Centers for Environmental Information, told CNN “In addition to several high pressure systems across the West and Northeast, the greater number of nighttime records versus the daytime can be partly explained by the wet conditions in some parts of the country. Clouds help make the daytime temperatures a bit cooler since they help block the sun’s solar rays, while trapping the Earth’s heat during the night.”

Still, many homes in large many large western US cities still have no air-conditioning including Los Angeles and San Francisco.

Ryan Littrell, a meteorologist at National Weather Service Los Angeles, told CNN “The seabreeze almost always blows the cooler air over the ocean over land to keep coastal areas fairly mild. As a result, air conditioning is not needed the vast majority of the year. It is warmer here than the first half of the 20th century, but we still have the cool Pacific Ocean to help.”
