Scorching temperatures came close to busting heat records in San Luis Obispo County on Monday.
In Paso Robles, the mercury soared to 109 degrees Fahrenheit, nearly squelching a record of 110 degrees set in 1956, according to PG&E meteorologist John Lindsey. The North County city saw a high of 107 degrees Sunday because of the inland heat wave brought on by a high-pressure ridge.
San Luis Obispo saw a high of 94, six degrees shy of the record of 100 degrees set in 1976.
Elsewhere in the county, Humbug Vineyards in Creston recorded a whopping 111-degree high, while nearby Windrose Farm experienced 109-degree heat.

Atascadero had a high of 108, the Lopez Lake Ranger Station in Arroyo Grande had a high of 107, and PG&E’s Energy Education Center in the Avila Valley got up to 105, Lindsey said. However, he noted that conditions at the education center cooled to 71 degrees in one hour because of a change in winds.
“Today was the hottest day,” he said, adding that cooler weather is on the way.
The high-pressure ridge is expected to weaken Tuesday through Friday, he said, bringing gradually dropping temperatures, lessening northwesterly winds and a persistent marine layer during the night and morning. Beaches and coastal valleys could see pockets of mist and drizzle, he said.
But the high-pressure ridge is expected to rebuild late in the weekend, Lindsey said, ensuring a sweltering Fourth of July holiday in the North County.
