What May feels like
Spring runoff has the river running high and the roar is at its most impressive, while the summer coach traffic hasn't started. Niagara-on-the-Lake across the river is in bloom and worth the drive if your passport is in your pocket.
Rain arrives about 7 days of the month, so keep one flexible day in your plans.
