Could hair loss be due to the season?

My hair suddenly started falling out a lot in the last month or two.
Especially after showering, I've definitely noticed a lot more hair on the floor. Since it started suddenly, I don't know if it's due to the season or if I'm starting to lose hair.
I haven't really changed my hairstyle or shampoo recently.
Has anyone else experienced a temporary increase in hair loss during specific seasons? I'm also curious how long that lasted!
