PM2.5 Forecast for Beijing – Sunday, April 20, 2014

Sunday's weather forecast presents a challenging scenario for prediction with conditions that could give us either good air quality or poor air quality.  We're feeling optimistic about our chances at improved air quality tomorrow, and you can see that in the graph.  We're expecting Unhealthy AQI readings overnight, but there is a decent chance that we could see those readings drop down as low as Moderate in the late morning and early afternoon.  Even if the weather doesn't cooperate, we should not see AQI readings any higher than Unhealthy tomorrow. 


MONDAY, April 21:  We could also have more moderate pollution on Monday.  There’s no clear trend at this point, but it looks like there is a decent chance that we could have Unhealthy or better conditions for most of the day.  If conditions are good on Sunday, that is a good sign of increased chances at better air on Monday.

TUESDAY, April 22:  We expect to be back to our normal spring/summer pattern on Tuesday:  high(er) AQI readings in the morning, then somewhat reduced AQI readings in the afternoon.  We should see the AQI at Unhealthy or worse for the entire day.

WEDNESDAY, April 23:  Expect more of the same on Wednesday:  higher pollution levels in the morning, then reduced pollution in the afternoon and evening.
