I'm in Iowa, but the '4 seasons' set up never made sense to me. It never actually aligned with what the weather/climate did. I remember bellyaching that I felt there were really 6 seasons here. I thought it was neat to learn that India's six seasons aligns more with the changes we experience here, though not the weather occurring.
It seems like(starting around January), we have a really cold and snowy two months, followed by about two months where its still cold, but the snow dies down and begins to melt. It isn't a flower budded spring that's often depicted, but a muddy mess with ice chunks in it. Then comes two months where stuff grows, things flower, and its pretty with moderate temperatures. Two months where its hot and dry, though everything's green. Bugs drone on. Summer at its highest. Then comes two months where the leaves turn pretty colors, things cool, we get rain showers. The last period its cold and dark, the leaves are gone. Not usually a whole lot of snow, but its brown and dead out, and unpleasant to behold.
It just seems the seasons(whatever you want to call them) change by about the two month mark, rather than the traditional three month. The Pagans have the wheel of the year, which changes about every 6 weeks, but I never felt that lined up with Iowa weather, either(being mostly based on European traditions).
