Is sultry weather a precursor to an earthquake?

The sultry weather has nothing to do with the earthquake, but it is found that the water temperature of rivers and lakes ponds changes inexplicably, and a large range of fish float to the surface and die (excluding pollution), which may be a precursor of the earthquake, because the pressure and heat energy inside the earth are released in the cracks at the bottom of rivers and lakes ponds, resulting in an increase in water temperature.
