How the comfort score works (v1)

Each month scores 0 to 10 from four weighted components: temperature (35%), sunshine (25%), humidity (20%) and rain (20%), with an extra penalty when heat and humidity combine. Personal tolerances reshape the score: your heat limit compares to how afternoons feel (heat index), your cold limit to typical nights.
