PM2.5 Forecast for Beijing – Saturday, March 29, 2014

Friday's good air quality never quite arrived, although we were headed in the right direction until late afternoon.  With the higher PM2.5 levels on Friday evening, that significantly shifts the forecast for Saturday.  We're expecting decreasing pollution overnight, but now it looks like we have little chance of making it down to Good or Moderate in the morning.  Instead, look for us to reach the day's low point at Unhealthy or Unhealthy for Sensitive Groups around 7AM or 8AM.  From then on, we're looking for increasing PM2.5 levels for the remainder of the day. 


SUNDAY, March 30:  The poor air quality should continue on Sunday, most likely giving us Very Unhealthy or worse air quality throughout the day. 

MONDAY, March 31:  We are expecting poor air quality again on Monday.  Look for Very Unhealthy or higher AQI levels in the morning, then we may see slightly improved conditions in the afternoon.

TUESDAY, April 1:  There's no end in sight for this run of poor air quality - look for the AQI to be at least Very Unhealthy in the morning, then possibly down into Unhealthy in the afternoon.
