São José extends along the Santa Catarina coast south of Florianópolis as part of the island capital's mainland metropolitan area, where native Atlantic Forest remnants, restinga coastal scrub, and introduced urban trees are the main pollen sources. The subtropical climate produces a well-defined pollen season, while the Atlantic Ocean proximity means onshore breezes can periodically disperse pollen and rainfall interruptions occur throughout the year throughout.
