The reason it is extra hazy is because of smoke. … These smoke particles are very small and light, and as they billow up into the atmosphere, the upper level wind pattern can transport these smoke particles thousands of miles from their original source, which in this case is from the wildfires out West and in Canada.
The difference today is more water vapor in the air at higher altitudes, changing the way light shines through the smoke particles. When sunlight is scattered through smoke and water vapor, we get grey skies.
The hazy skies seen Thursday afternoon across much of Southern California are due to shifting wind patterns and wildfires in Northern and Central California, officials said.
Pennsylvania Skies Got Hazy Because Of Intense Western Wildfires. … Wildfires in the American West, including one burning in Oregon that’s currently the largest in the U.S., are creating hazy skies as far away as New York as the massive infernos spew smoke and ash into the air in columns up to six miles high.
Haze is caused when sunlight encounters tiny pollution particles in the air. Some light is absorbed by particles. Other light is scattered away before it reaches an observer. More pollutants mean more absorption and scattering of light, which reduce the clarity and color of what we see.
Haze often occurs when dust and smoke particles accumulate in relatively dry air. When weather conditions block the dispersal of smoke and other pollutants they concentrate and form a usually low-hanging shroud that impairs visibility and may become a respiratory health threat.
In heavily polluted air, the sky may appear yellow or brown, and this is due to the particles being able to scatter the light to produce these colors. This phenomenon is called Mie scattering. To sum it up, the way light is scattered determines the color of the sky.”
Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from the horizon has passed through even more air than the sunlight reaching us from overhead. The molecules of gas have rescattered the blue light in so many directions so many times that less blue light reaches us.
As white light passes through our atmosphere, tiny air molecules cause it to ‘scatter’. The scattering caused by these tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. … Therefore, blue light is scattered more than red light and the sky appears blue during the day.
South Florida’s Smoky, Hazy Skies Caused By Big Cypress Brush FiresSmoke from several large fires burning in the Everglades is causing hazy conditions in South Florida.
Five things you need to know: The American Lung Association’s air quality report gave the counties in Southern California an ‘F,’ making LA the worst in the U.S. Smog — the yellowish shroud that often hangs over us — is actually ozone. … Bad ozone can cause asthma attacks, strokes, heart attacks and even lung cancer.
Los Angeles began 2020 with a clean-air streak but ended with its worst smog in decades. … The year 2020 will instead go down as one of Southern California’s smoggiest in decades.
The haze that fell over Pennsylvania surprised Sublette. … Though fires are still burning in the western U.S., the haze has mostly cleared. The Department of Environmental Protection issued Code Orange Air Quality Alerts on Tuesday and Wednesday.

Haze particles can sometimes affect the heart and lungs, especially in people who already have chronic heart or lung disease e.g. asthma, chronic obstructive pulmonary disease (COPD), or heart failure. There may be up to one to three days of time between exposure to haze and health effects/ symptoms.
HAZE consists of sufficient smoke, dust, moisture, and vapour suspended in air to impair visibility. HAZE pollution can be said to be “transboundary” if its density and extent is so great at source that it remains at measurable levels after crossing into another country’s air space.
But much of what we see as “haze” is, in fact, a form of diffuse air pollution and, as such, a cause for concern. Although haze can affect many things, it is most noticeable for reducing air quality, especially visual range (visibility) and contrast.
Fog and haze differ in that fog is a thick, opaque effect that lasts a short time, while haze is a thin, translucent effect that lasts a long time. Fog is used as a special effect, whereas haze is used for lighting/atmosphere enhancement.
The moisture particles are so small that they can bend the light and alter its appearance to the observer. … If this blue scattered light is set against an environment heavy in red light—during sunset for instance—and a dark gray thunderstorm cloud, the net effect can make the sky appear faintly green.
Mostly the area of the sky around the moon , as seen from earth, appears white due to the moonlight that it reflects and refracts due to air particles. If you live in a city with relatively less pollution then the stars from our galaxies and from other will appear to shine bright and give a white hue to sky.
Originally Answered: If our Sun was red, what color would the sky be? Blue. The Sun would appear white, because very bright light sources saturate the color receptors in the eye and look white.

“The smoke rides over the fog,” said Dr. John Balmes of UC-San Francisco, who studies the respiratory health effects of air pollutants. “Mist keeps a lid on the fine particles, up higher, from coming down and getting into our lungs,” he said. “Foggy days are very good for protecting us.”
