Here we are, one month into spring, and we're complaining about how it's still cold and not summery. We've had a few very nice days, but also some lousy weather. I have a theory: I think we're having a very normal spring. It's just that we're not used to it.

The past few springs have been unseasonably warm. Last year, March was sunny and warm and beautiful. Then April and May were washouts. We remember the warm and beautiful part, but March is way too early for that kind of weather.
In France there are (at least) two sayings about spring. The first is
en avril, ne te découvre pas d'un fil; en mai, fais ce qu'il te plaît. Roughly translated, it means "in April, don't remove a stitch of clothing; in May, do what you like." That's an indication that April can be chilly, but May should be nice.
The other is not really a saying, but a warning that one should not set plants out in ones garden before
les saints de glace (the ice saints' days). The saints in question are Saints Mamert, Pancrace, and Servais whose days are celebrated the 11th, 12th, and 13th of May, respectively. The warning originated in the Middle Ages as a rule of thumb that, until those dates in May, there can still be a crop-damaging freeze.
So, I think we're having a normal spring and we just don't realize it. Nor do we like it much.
