Normal Sudoku rules apply.

PRECIPITATION - The rainfall in each column is the sum of digits in its blue cloud cells. In the blue box, write exactly the average rainfall of all 9 columns.

TEMPERATURE - Numbers increase along thermometers, starting from the bulb (the top thermo ends somewhere inside the cloud). Only one digit appears on all 4 thermos. Write this digit in the red box.

WIND - In the grey box, draw a wind symbol like the ones seen around the grid, pointing in some direction. Each digit N on a wind symbol whose "hook" end is pointing the same direction as the one you drew places a copy of itself N steps in that direction. Wind symbols pointing in other directions can be ignored.

Example: if your symbol points South East, and there were a 2 in R2C1, then R4C3 would also need to be a 2.
