Downtown Los Angeles reached a temperature of 113 degrees on Monday, September 27, 2010 at 12:15 pm, the highest temperature officially recorded in downtown Los Angeles since the Weather Service began keeping records in 1877.
However, what the top temperature was at that location–on the campus of the University of Southern California– for the day will never be known, because the thermometer broke, reports the Los Angeles Times.
According to the article, "Shortly after that banner moment [of 113 degrees], the temperature dipped back to 111, and then climbed back to 112. Then at 1 p.m., the thermometer stopped working. The weather service office in Oxnard rushed an electronics technician 60 miles southeast to the USC campus to repair the thermometer, which is actually a highly sensitive wire connected to electronic equipment. Because of the snafu, officials said it’s possible Monday’s temperature actually was hotter than 113 — but they might never know."
The prevous record of 112 degrees was set on June 26, 1990, the article said.
Bill Patzert, a climatologist at NASA’s Jet Propulsion Laboratory in La Cañada Flintridge told the L.A. Times, "Five days ago, we saw some of the lowest daytime temperatures we’ve seen in 50 years. And today was a once-in-a-century day. So anybody that thinks Southern California doesn’t have weather, we definitely have had a major exhibition by Mother Nature in the last five days."
