PM2.5 Forecast for Beijing – Wednesday, August 27, 2014

Our hoped-for better than average conditions are in place, and it looks like there is a good chance that they will stay around for most of the day.  But at some point this afternoon or evening, we do expect the pollution levels to start increasing again. 

EXTENDED FORECAST

THURSDAY, August 28:  Thursday should bring us back to about average levels, Unhealthy for likely the entire day.

FRIDAY, August 29:  Friday should again have us at Unhealthy conditions for the entire day.

PM2.5 Forecast for Beijing – Tuesday, August 26, 2014

We've been lucky to keep better than average air quality around overnight and through the morning, and now it looks like we have a good chance that it will stay around for most of the day.  We should again see the pollution accumulate somewhat in the late afternoon and evening, but it will likely be late before we see Unhealthy conditions.

EXTENDED FORECAST

WEDNESDAY, August 27:  We’re on the fence for Wednesday's forecast.  Some of the signs point to average air quality, but there are other signs pointing toward better than average conditions.  If we have to choose, we'll go with better than average conditions as the most likely scenario for Wednesday. 

THURSDAY, August 28:  Thursday should keep the pollution around average levels, Unhealthy for likely the entire day.

FRIDAY, August 29:  Friday should again have us at Unhealthy conditions for the entire day.

PM2.5 Forecast for Beijing – Monday, August 25, 2014

TUESDAY, August 26:  Tuesday may start off with better than average air quality, but we expect to be back at Unhealthy conditions by late afternoon or early evening.

EXTENDED FORECAST

MONDAY, August 25:  For now it looks like the better than average air quality should carry over into Monday, possibly through most of the afternoon, but we should see the pollution start to accumulate again before the day is over.

TUESDAY, August 26:  Tuesday may start off with slightly better than average air quality, but we expect to be back at Unhealthy conditions by late afternoon or early evening.

We've seen poor air quality overnight, and that should continue throughout the rest of the day. 

EXTENDED FORECAST

MONDAY, August 25:  For now it looks like the good air quality should carry over into Monday, likely into the early afternoon, but we should see the pollution start to accumulate again before the day is over.

PM2.5 Forecast for Beijing – Tuesday, August 19, 2014

Some of the volatility we saw in the AQI over the weekend has gone away, unfortunately leaving us with readings steadily in the Unhealthy range.  We expect that to continue for the rest of the day and into Wednesday. 

EXTENDED FORECAST

WEDNESDAY, August 20:  Wednesday should bring us another day with average conditions, although we are starting to see a possibility of improved air quality in the afternoon.  If that pans out, we could see Moderate or Unhealthy for Sensitive Groups conditions in the afternoon and evening.

THURSDAY, August 21:  Thursday looks similar to the days before, so we have to go with a prediction of average air quality for the day.  And again there is some indication that the air quality might be somewhat better in the afternoon.

FRIDAY, August 22:  Friday’s forecast should have us at Unhealthy conditions throughout the day.

Monday, August 18, 2014

PM2.5 Forecast for Beijing – Monday, August 18, 2014

Sunday, August 17, 2014

PM2.5 Forecast for Beijing – Sunday, August 17, 2014

Within the last 16 hours, we've seen a seven-fold increase in PM2.5, then a drop of more than 90%.  In this environment, it's very difficult to predict where things will go next, but we'll give it a shot.  The currently decent air quality is unlikely to stay around for long, so look for a return to average, Unhealthy conditions during the day. 

EXTENDED FORECAST

MONDAY, August 18:  There is a slight chance of improved air quality in the early hours on Monday, but it is most likely that we will see Unhealthy conditions instead, still average for this time of year.

EXTENDED FORECAST

SATURDAY, August 16:  There is still a slight chance of improved air quality in the morning, but the most likely scenario is average, Unhealthy conditions throughout the day.

Monday, August 4, 2014

PM2.5 Forecast for Beijing – Monday, August 4, 2014


We're back!  And just in time for a chance at some decent air quality for the first time in a week.  We should see the pollution falling during the morning hours, possibly leaving us at Good/Moderate AQI readings for a large part of the day.  We say possibly because the rainy conditions may spoil the clearing skies and hold in some of that pollution.  In any case, we should see the pollution climbing again in the evening. likely back toward Unhealthy conditions.
