The Creek and North Complex wildfires are burning more than 300 km north of San Francisco, but strong winds have carried smoke to the Bay Area.
In a video posted to Twitter on Wednesday, Bay Area Air Quality district meteorologist Jarrett Claiborne explained the phenomenon, saying visible sunlight is a combination of all the colours of the rainbow.

“When we have particles in the air, those can act as filters and can scatter certain colours out,” he explained. “With smoke, for example, that’s filtering out other colours allowing red, orange and yellow to reach the surface.”
“That’s why we have those colours this morning,” he said.
According to Claiborne, by morning much of the smoke was above the thanks to a “marine layer,” but that it was expected to make it to the ground level in some areas by the afternoon.

Erin DeMeritt, a spokesperson for the Bay Area Air Quality Management District, told CNN the massive plumes of smoke generated by the wildfires raging across the state have led to the longest stretch of unhealthy air quality alerts on record in the Bay Area.
There have now been 25 straight days of “Spare the Air” alerts, DeMerritt said.
The current alert has been extended until Friday.

What’s more, Drew Peterson, a meteorologist with the National Weather Service’s Bay Area, told The Associated Press that the smoke blocked out so much sunlight on Wednesday that a forecast for temperatures to climb to 32C dipped to 15.5C.
Peterson said it is as if the area is in a “perpetual morning without the sun to help us warm up.”
