Similarity averages twelve monthly scores: temperature 45%, rainfall 30%, humidity 15% and solar radiation 10%. These editorial weights measure neither comfort nor the probability of rain. Each difference is divided by its scale and bounded between 0 and 1; high and low temperatures have equal weight within their component.
