It is a fair point on climate change. I'm not really an expert on this, but I'll make some various points...

I think winters have become drier, but April can be absolutely torrential.

The specific location can also make a difference. I'm near the base of a mountain which I believe can prop-up the underground water table nicely, and can certainly cause more rain.

I think Portugal being costal also helps with rainfall, certainly compared to the plains of Spain further East.

Try and get some data for the last decade or two. That will probably be more useful than any local anecdotes. But local terrain/micro-climates will make a difference.
