As we dive headlong into summer, there’s one thing you can be sure of. The weather is going to heat up, and with it pollution levels will rise. That’s going to be especially true as the wildfire season kicks into gear, and the recent Canadian wildfires caused New York City to experience the worst pollution levels ever recorded.
It helps to know how clean or dirty the air is in your local area. That way you can prepare yourself (and your lungs) to handle any spikes in particularly poor air quality, Whether that’s by covering up with an N95 mask, or using one of the best air purifiers to clean up the air you breathe.
Fortunately Google Maps comes with a free and simple tool to check the air quality in your neighbourhood. The air quality layer sits on top of the normal Google Maps, and uses a simple color-coded scale to show just how clean or dirty the area is in a supported area. Here’s how to check local air quality in Google Maps.
How to check air quality with Google Maps
- Open Google Maps on mobile or desktop
- Zoom into a location to check
- Open the layer menu
- Tap Air quality
Read on to see full illustrated instructions for each step.
1. Open Google Maps on your device
Mobile users should open the Google Maps app. Desktop users should head to the Google Maps website.
2. Find the area you want to check
You’ll need to do all your navigation before checking air quality data. The easiest way is to search for a specific address or location with the search bar at the top of your screen. Alternatively, hit the compass icon in the bottom right to go directly to your current location.
Just be aware that Google Maps doesn’t offer air quality data for every single location, primarily serving urban and built up areas across the United States.
3a. (Mobile) Open the layer menu
On Android and iOS devices Google Maps’ layer menu can be found in the top right, underneath the search bar. It looks like a square above a downward-facing chevron. Tap it to open the layer menu.
3b. (Desktop) Open the layer menu
On desktop the layer menu is on the bottom left. Here you’ll find a box that says “Layers” with the same square and chevron icon. Hover over the square with your mouse then click the More option on the right.
4. Select Air Quality
Air quality can be found at the very end of the Map Details section of the layer menu, represented by a green circle with three wavy lines in the middle. Select this to switch on the Air quality layer.
The air quality layer overlays various bits of information onto the standard Google map. Smoke plumes are presented when they’re happening, but the main focus is the color-coded dots spread over various areas of the U.S.
These dots are color-coded from green to purple. Green is good quality air, yellow is moderate and orange is designated “unhealthy for sensitive groups”. Red is unhealthy for everyone, maroon is very unhealthy and purple is hazardous.
