Somehow a whole growing season passed without any Bordeaux climate updates. Here it is.
Bordeaux 2009 Growing Season Temperatures
The climate is fairly unremarkable in terms of both temperature and precipitation. The first graph shows the daily average temperature at the Bordeaux-Merignac airport. With only one significantly warm period, it’s safe to say the temperatures were rather average. In fact, the average temperature of 2009 from April to Sept 1 is only a few tenths of degrees different than the long term average (red line).
Amazingly, precipitation is no different.
Bordeaux 2009 Growing Season Accumulated Precipitation
The early part of 2009 (blue line) was wetter than average but the latter half of the season has been drier than average. Since the two lines practically touch, the precipitation this growing season is right on average as well.
The implications of this is that the quality of wine in Bordeaux will be neither outstandingly good or bad. 2009 should NOT end up being an outstanding vintage. Not a bad one, either.
Coming next, I’ll apply the Ashenfelter model to develop a quantitative estimate of Bordeaux wine quality for 2009.
