Swirling winds helped push a layer of cool marine air across much of Southern California on Saturday, providing a slight respite from the blistering heat wave that has created dangerous fire conditions across the state.

Marine Layer Brings Temporary Cooling

The whirling air currents deepened and extended the marine layer farther inland into coastal valleys, helping temperatures drop about 10 degrees below Friday’s levels, said Robbie Munroe, a meteorologist with the National Weather Service in Oxnard.

The slightly cooler weather is expected to continue until midweek.

Cooling Trend and Heat Advisories

The cooling trend prompted the Weather Service to call off excessive-heat advisories and warnings in many of the coastal valleys. However, advisories remained in place for deserts, mountains, and the Santa Clarita Valley, Munroe said.

Temperature Drops in Key Areas

  • San Fernando and San Gabriel Valleys: Temperatures had been expected to range from the mid-90s to a high of 105 degrees but fell below those expectations on Saturday.
  • Chatsworth: Dropped to a high of 92 degrees from 109 degrees on Friday.
  • Saugus: Cooled down to 100 degrees from 118 degrees the previous day.
  • Woodland Hills: Fell to 96 degrees from 106 in that period.
  • Palm Springs: Cooled to 114 degrees on Saturday, down 10 degrees from Friday.
  • Downtown Los Angeles: Maintained a high of 87 degrees on Saturday, consistent with Friday.

Record-Breaking Heat in Other Areas

Despite the cooling in some regions, extreme heat shattered records in other areas on Saturday. Palmdale tied its all-time record of 115 degrees, and Death Valley set a new record for July 6 with a high of 128 degrees.

Red Flag Warnings and Fire Danger

Extreme heat, low humidity, and strong winds prompted officials to issue a red flag warning through the weekend along the 5 Freeway corridor and in the Antelope Valley foothills, said Joe Sirard, another National Weather Service meteorologist in Oxnard.

“Fires are dangerous anywhere, but this is really a heightened danger,” Sirard said, adding that blazes in these conditions “will spread rapidly — explosively — and it’s extremely dangerous for firefighters.”
