Fresno tied its record for high temperature on Saturday when the thermometer reached 105 degrees at Fresno Yosemite International Airport, the National Weather Service said.
The reading came at 5 p.m., typically the hottest time of the day.
That temperature was also reached on June 4 in 1996, 1992 and 1935, said NWS meteorologist Scott Rowe.
Not only was a hot, it was also dry. The NWS said humidity at that time was near 10 percent, meaning there was little moisture in the air.
The average high for June 4 was 89 degrees, so Fresno was 16 degrees above normal, Rowe noted.
Sunday will remain hot but slightly cooler in Fresno, with a high of 102 degrees. Triple-digit heat will remain in place thanks to a high-pressure ridge covering California until Wednesday, when the high falls back into the upper 90s, Rowe said.
