The weather in Metz is cooler than Atlanta. I would say it's more like Virginia or the DC area. In general the winter is cloudy and dark and wet.
The summers are beautiful, the fall and spring as well. Lots of fog in the spring. That's my experience of one year.
Today, December 19, 2005, I woke up to a beautiful light snowfall. Perfect for the season.
Here's a view from my office window looking across the lake towards Supelec.
