I know next to nothing about lidar engineering but 60GHz band radars can still function out to several hundred meters in rain. It is significantly attenuated as the rain rate (in mm/hour) increases, but it takes a lot of rain to make it completely useless.

This depends on how powerful your antenna are, $200 wigig transmitters will struggle with much range over those distances.

And how directional and narrow the gain pattern is.

Summers in South Florida will put that to the challenge.
