I'm reminded of Eberron, which had planes coming into overlap in various places at various times, tied to the rotation of the planets. So I could even see that being part of extra-planar migration and just one more type of season. "Och, getting that time every three years for the Fire Plane to get close, better get some barrels of water ready, and make sure no fire-critters wander into the barn."
Also things like samon swimming upstream to spawn, you don't want to live anywhere near the spawning grounds of (insert monster here).
