SAN FRANCISCO (KGO) -- The Bay Area woke up to one of the strangest sights ever remembered. Darkness mixed with an orange sky has lingered throughout the day caused by fog and heavy smoke from those wildfires.
Some of you may have wondered if this was "the day the earth stood still."
"We woke up around 7 in the morning, opened the curtains and it seemed to be night time. It was pretty scary," expressed Daniela Hernandez who, was visiting from North Carolina.
Alcatraz from Fisherman's Wharf looked like something out of mystical novel. Tourists were compelled to record some of San Francisco's iconic sights when day turned to night.
Even the mayor felt it was necessary to reach out to San Franciscans on social media explaining how the combination of fog and smoke from wildfires was creating the orange sky.
Then came a public service announcement.

"It hasn't really impacted our air quality yet because of our marine layer and because the smoke is so high," explained Breed.
Construction workers used lights Wednsday morning to work in the dark.
In any given afternoon, John's Grill in San Francisco is packed with customers having lunch, but the darkness kept them away.
"I have never seen anything like this in my entire life. It's quite frightening. I hope everyone is safe. I hope everyone keeps safe," said John Konstin, Jr.
Wednesday's anomaly served as a reminder of what's going on in parts of the state.
"I feel bad for the people who are right in the heart of it right now because this looks terrible but imagine if you're right there," added Evan Brenner of San Francisco
The smoke over the region is coming from the Bear Fire, one of the wildfires burning in Butte County that makes up the Northern Complex. The Bear Fire exploded in size overnight to 58,000 acres, prompting evacuations and spewing out smoke over the Bay Area.
But a thick marine layer kept air quality in much of the Bay Area relatively good, despite the ominous sky color.
"The marine layer is a stable area of air that does not rise, and so we're continually pumping in cleaner air from over the ocean," explains ABC7 News Meteorologist Mike Nicco.
That's why the sky is so dark, with a yellow or orange hue, but you may not smell smoke when you step outside. Read more here.
