Mask, or no mask? Planning your day has gotten so much easier.

The Real-Time Air Quality Index Visual Map is a website that allows users to read AQI readings from various environmental substations around their area in map form. Get a better idea of the local air pollution situation by seeing the differences in air quality by geographical location.

The top map is a representation of the PRD via clicking on “Guangdong“, but here’s Guangzhou:

Dongguan:

And Shenzhen:

There’s also listings for other Guangdong and PRD cities like Zhuhai, Zhongshan, Foshan, Huizhou, Shunde, Jiangmen, Maoming, and Hong Kong, some of which are the cleanest cities in China.

As this map is world-wide, you can also access other areas. At a glance, you can see the very reason why residents of Shanghai, Beijing, and Chengdu are now flocking to the beautiful, sunny south.

Warning: once you start exploring this map, it’s hard to stop. After living in a polluted place like China, you’ll start fancying yourself living in some remote areas. After looking at this map, I’m now sorry I ever made fun of Thunder Bay, Ontario, though I still don’t mind the 15 hours it took to leave there.
