I live near Bremerhaven in North-West Germany.
In the local Zoo, called "Zoo am Meer" (Zoo at the sea) one can find this Weatherstone.
The translation of the board below it:
Weather station "Zoo am Meer"
| Shadow beneath stone | sunny |
| Stone is wet | rainy |
| Stone is barely visible | foggy |
| Stone is white | snowy |
| Stone is moving | windy |
| Stone is shaking | hurricane |
| Stone is under water | flood |
| Stone fell down | earthquake |
| Stone is gone | theft |
This picture was taken by me with a Xiamo Redmi Note 7 last year.
