One of the most puzzling mysteries of Hogsmeade is that it is always snowy in the village, despite being just a short walk away from Hogwarts, which clearly experiences all four seasons in both the films and in the books.
In most of the films, Harry, Ron, and Hermione’s visits to Hogsmeade usually occurred in the wintertime, which explains why there would be snow in the village. However, during the Deathly Hallows Part II, fans aptly noticed that despite it being springtime and there being no snow at Hogwarts, Hogsmeade remained snowy during their visit there.
According to the filmmakers, Hogsmeade is above the snow line. This means that there is snow in the area 365 days of the year, despite it being so close to Hogwarts. This is not a feature in the books, although it’s hard to deny how picturesque Hogsmeade is with snowy rooftops.
