Paso Robles swelters through third-hottest August ever

It was a warm August in the North County, but not quite one for the record books.

Temperatures at the Paso Robles Municipal Airport exceeded 100 degrees on 18 days last month, said PG&E meteorologist John Lindsey. On Aug. 10, the mercury reached 110 degrees, setting a record for that day.

The average mean temperature in August in Paso Robles was nearly 78 degrees, the third-highest mark on record, Lindsey said. Only 1998 and 1967 exceeded that average.

The average mean temperature is determined by calculating the average hourly temperature for an entire day. It is the best statistic for detecting temperature trends because it averages temperatures from throughout a day’s 24-hour period, Lindsey said.

“With a warming climate, we are finding that there are more records broken overnight than during the day,” he said.While August has been warmer than normal, July was cooler than normal. Temperatures in Paso Robles were 1.4 degrees below average, Lindsey said.

That ran counter to the temperatures elsewhere across the country.

The National Oceanic and Atmospheric Administration reported that July was the hottest on record nationwide, with drought in many parts of the country.

The warm weather is expected to continue through the Labor Day weekend. North County temperatures are forecast to be in or near the 90s, while highs in San Luis Obispo are expected to be around 80. Overnight lows will be in the 50s.
