Is the leakage of toilet floor related to weather or air pressure?

It has nothing to do with weather and air pressure.

There are two reasons why the toilet leaks. The buried water pipe leaks or the waterproof layer is damaged.

Turn off the main water gate in your house and let the water out of the pipe. If it will be fine after a while, it means that the pipeline is leaking. Replacement and maintenance need to smash tiles and pry the floor.

Be careful not to splash water to keep the ground dry, and the situation has improved for a while, which is caused by the failure of the waterproof layer. If you want to cope with it for a few years, you can brush transparent paint. If you want to solve it completely, you need to smash the tiles to pry the floor and choose the right materials to redo it.
