This is useless because all metropolitan areas around the world have become urban heat islands since the post-ww2 industrial boom. Millions of tons of asphalt & concrete have been poured in Madrid over the past several decades, which absorb and emit heat. There are now far more vehicles, industrial sites, and other heat-emitting objects, contributing to localized heat. Madrid in particular has immense urban density and a robust highway network going through the city. You'd have to be a complete dullard to not think the city was going to be several degrees locally warmer now, on average, than it used to be.
