Modesto baked under record heat Monday.
By early evening, the thermometer had reached 107 degrees, according to weather data collected by the Modesto Irrigation District. That topped the previous historic high of 105 degrees, set in 1945.
Midafternoon Monday, Stanislaus County Office of Emergency Services Assistant Director Dale Skiles said OES had heard no reports of heat-related illnesses or deaths as the day grew increasingly hot.
OES has been in communication with the emergency managers of the county’s nine cities, as well as county department heads, he said, and while not all reports had come in, none had reported problems. As the National Weather Service’s excessive-heat warning remains in effect through Thursday night, OES continues to post advisories on Facebook and Twitter; search @StanEmergency. The office also is keeping lines of communication open with other emergency responders, including the American Red Cross, Skiles said.

Sunday’s high of 104 degrees in Modesto tied the record temperature set in 1957, according to MID data kept since 1939. Back in ’57, though, there was nighttime relief, with a low of 59 degrees. The low in Modesto on Sunday night? MID says it was 80.
The National Weather Service keeps its own records, of course. It posted on social media that Modesto hit 105 on Sunday, breaking a record of 104 set in 1957.
Either way, it was hot, and will continue to be.
The average high temperature for June 19 is 90 degrees, according to MID. But the streak of triple-digit days underway here is anything but average. According to the seven-day forecast from the weather service, Modesto won’t see a daily high in the 90s again until Sunday.
Tuesday’s and Wednesday’s high should be near 106. Thursday is expected to be hotter still – near 108. The nighttime lows for the next few nights are around the mid-70s.
A gradual decline in daily highs starts Friday, which will reach near 103. The low will be around 71.
Saturday’s high should near 101, with a low around 70. Sunday’s high is forecast to be near 98. And Monday should be near 98.
Public safety agencies continue to remind people via social media to stay hydrated and out of the sun.
▪ Walk dogs in the coolest part of the day. Pavement too hot for bare feet is too hot for paws.
▪ Check in on the elderly, sick and those without air conditioning.
▪ Do not leave young children unattended in or around a swimming pool, and if enjoying a reservoir, use life jackets.
▪ Wear lightweight, light-colored clothing.
▪ Work outdoors only early or very late in the day.
▪ Wear sunscreen.
▪ Avoid alcohol.
The Stanislaus County Office of Emergency Services posted on its Facebook page that children, disabled or elderly adults or pets never should be left in parked vehicles. “Leaving the windows slightly open does not significantly decrease the heating rate,” it warns. “The effects can be more severe on children because their bodies have not developed the ability to efficiently regulate its internal temperature.”
A graphic shared by the weather service shows that on a 105-degree day, the sun can heat the interior of a vehicle to 118 degrees within 10 minutes and to 152 degrees within an hour. Even on an 85-degree day, the interior reaches 132 within an hour.
