Current viewpoint ranking
Loading current ranking…
A high model score does not guarantee a visible rainbow. A small cloud can block the sun instantly, and local spray is turbulent.
Where to stand changes as the sun moves and the wind shifts the mist. This ranking uses the same live forecast engine as the main Niagara Rainbow tool.
Comparing sun angle, direct sunlight, mist direction and visibility.

A rainbow forms opposite the sun. As the sun moves through the sky, the favorable viewing geometry moves too. Wind also changes where the strongest mist plume sits.
