Las Vegas has officially broken a weather record, and it’s a good one, for a change.

The National Weather Service office in Las Vegas announced that Monday’s high of 97 degrees marked 291 consecutive days where the temperature failed to reach 100 degrees.

This breaks the 290-day cool streak set from Sept. 13, 1964, to June 29, 1965. Weather data for Las Vegas only goes back to 1937, according to the National Weather Service.

Tuesday’s predicted high of 99 degrees will extend the record to 292 days, but that will probably be where it stands. A high of exactly 100 is called for on Wednesday, June 28, leading into a probable excessive heat warning this 4th of July weekend, with a forecast high of 112 degrees on Sunday.

The temperature in 1964 and 1965 will still top the current cool streak in one regard, however. In 1965, the thermometer didn’t hit 100 degrees until June 30. The mercury in Las Vegas usually hits 100 on May 24. The earliest it ever did was on May 1, 1947.

One possible reason for this year’s unseasonably mild late spring and early summer may be the arrival of an El Nino event, which was heralded by a watch released by the National Oceanic and Atmospheric Administration’s Climate Prediction Center in April.

El Ninos tend to be associated with above-average summer precipitation and, therefore, cooler temperatures. However, it’s difficult to predict their specific effects on Las Vegas weather.
