Yes, in order for data to be binomial, it has to have only two mutually exclusive outcomes for each trial. Like heads or tails, true or false. Not a rainfall measurement.
And the outcomes have to be independent, daily rainfall is not, since weather systems can last for more than one day.
And the process has to be stationary, with the probability of success constant from trial to trial. So, no shifts in climate.
Strike three.
