Interesting.

Even in the warm Florida, most births take place between July and September:

Summertime Mystery: More Born, Fewer Die in August

This says that many areas in Europe have a different pattern.

Also, seasonal variation used to be particularly pronounced in the South with a particular low in August.  One theory is that air conditioning has dampened the trough (ie it is not more conception in cold weather, but less conception in hot weather).

My understanding is that this year of the Water Dragon is particularly auspicious.  Seasonality of births might depend on whether parents planned ahead, or belatedly began yesterday.
