On September 9, 2020, San Francisco residents woke up to an eerie, apocalyptic scene as the sky turned a deep orange color due to wildfire smoke blanketing the region. This phenomenon, now known as Orange Skies Day, was a stark reminder of the increasing impact of climate change and wildfires on daily life in the Bay Area.

Key Points
- Wildfire smoke particles in the atmosphere filtered out shorter wavelengths of light, causing the sky to appear orange
- The orange skies significantly impacted daily life and posed public health risks due to poor air quality
- While rare, similar events have occurred in the past and may become more frequent due to climate change
Understanding the Orange Skies Phenomenon
The Science Behind the Color
The orange color of the sky during this event was caused by smoke particles in the atmosphere filtering out shorter wavelengths of light, such as blue and green, while allowing longer wavelengths like red and orange to pass through. This is similar to what happens during sunrise and sunset, but the effect was intensified and prolonged due to the dense smoke from nearby wildfires.
Wildfires and Climate Change
Role of Wildfires in Causing Orange Skies
The orange skies over San Francisco were a direct result of multiple wildfires burning across California and the West Coast. As these fires consumed thousands of acres of land, they released massive amounts of smoke into the atmosphere, which was then carried by wind currents to the Bay Area.
Connection Between Climate Change and Increased Wildfire Activity
Climate change has been linked to an increase in the frequency and intensity of wildfires in California and other parts of the world. As temperatures rise and droughts become more common, the risk of wildfires increases, making events like Orange Skies Day more likely to occur in the future.
Impact on San Francisco’s Daily Life
Public Health Concerns
The poor air quality caused by the wildfire smoke posed significant health risks to San Francisco residents, particularly those with pre-existing respiratory conditions. Health officials advised people to stay indoors, keep windows and doors closed, and use air purifiers if possible.
Changes in Daily Activities
The orange skies and poor air quality forced many San Franciscans to adjust their daily routines. Outdoor activities and sports were canceled or moved indoors, and local businesses, already struggling due to the COVID-19 pandemic, faced additional challenges as people stayed home to avoid the smoke.
Historical Context and Frequency
Past Incidents of Orange Skies
While the September 2020 event was particularly striking, it was not the first time San Francisco experienced orange skies due to wildfire smoke. In 2018, the Camp Fire in Northern California caused similar conditions in the Bay Area. Historical records also show that the city has dealt with the impacts of wildfires and smoke for over a century.
Predictions for the Future
As climate change continues to exacerbate wildfire conditions, researchers predict that events like Orange Skies Day may become more common in the future. This underscores the need for urgent action to address climate change and improve wildfire management strategies.
Community and Government Response
Public Safety Measures
In response to the orange skies and poor air quality, local government agencies and health departments issued warnings and guidelines to help residents stay safe. This included advising people to stay indoors, providing information on air quality levels, and offering resources for those most vulnerable to the effects of smoke.
Policy and Environmental Action
The Orange Skies Day event has also sparked discussions about the need for stronger policies and actions to address climate change and reduce wildfire risks. This includes efforts to reduce greenhouse gas emissions, improve land management practices, and invest in wildfire prevention and response capabilities.
Visuals and Personal Accounts
Photographs and Videos
The striking visuals of San Francisco under orange skies quickly spread across social media and news outlets, with countless photographs and videos capturing the surreal scene. These images showcased the impact of the event on the city’s iconic landmarks and landscapes, from the Golden Gate Bridge to the Transamerica Pyramid.
Stories from Residents
San Francisco residents shared their personal experiences and reactions to the orange skies on social media and in interviews with local media outlets. Many described feeling a sense of unease and disbelief at the apocalyptic scene, while others expressed concerns about the health impacts of the smoke. Despite the challenges, the community also demonstrated resilience and solidarity in the face of the crisis.
