San Luis Obispo shattered a 20-year heat record on Thursday.
The San Luis Obispo County Regional Airport unofficially recorded a high temperature of 104 degrees at 2:25 p.m. on Thursday, according to meteorologist John Lindsey.
That beats the former record for the same day, set at 101 degrees in 2004, he said.
The airport’s all-time-high temperature record was set at 117 degrees on Sept. 6, 2020. Meanwhile, the mercury hit 120 degrees at Cal Poly that day, Lindsey said.
Paso Robles, meanwhile, just barely missed out on breaking its own daily heat record .
According to Lindsey, the North County city hit a “sweltering” 107 degrees, slightly below the previous record of 109 degrees set on the same day in 1988.
Lindsey said though temperatures would continue in the triple digits in Paso Robles on Friday, the high was expected to be only 110 degrees — well below the previous Sept. 6 record of 117 degrees set in 2020.
Heat wave to last through the weekend
The hot weather is part of a heat wave that’s bringing dangerously high temperatures to much of California and is expected to last for the next few days.
On Friday, San Luis Obispo should expect a high temperature of 99 degrees, cooling to 57 degrees overnight, the Weather Service said.
Meanwhile, Paso Robles will be scorched by a high of 110 degrees on Friday, lowering to 61 degrees at night.
The county is also in for a warm weekend.
San Luis Obispo could have a high of 94 degrees on Saturday and 89 degrees on Sunday. Monday and Tuesday will cool to temperatures in the 80s.
In Paso Robles, the mercury will reach 105 degrees on Saturday and 102 degrees on Sunday. Monday could have a high of 100 degrees and Tuesday a high of 95 degrees, the Weather Service said.
The National Weather Service also issued a heat advisory for the San Luis Obispo County mountains and interior valleys until Saturday at 8 p.m.
How to stay cool
The Weather Service warned that “dangerously hot” conditions could be risky for people with heat-related illnesses.
“Warm overnight low temperatures will bring little relief from the heat,” the Weather Service said.
Do not leave children or pets unattended in vehicles, it added.
“Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun and check up on relatives and neighbors,” the Weather Service said. “Take extra precautions when outside. Wear lightweight and loose fitting clothing. Try to limit strenuous activities to early morning or evening. Take action when you see symptoms of heat exhaustion and heat stroke.”
