Sometimes there are nice summaries for your audience. Where this picture was taken, if the sun sets on the south side of the street, it's good to have a jacket for the evenings, and chains in the car if you drive. Perhaps shorten it to "south sunset invites cold and wet."
Useful, easy to teach... except the assumptions.
It's the northern hemisphere, the right combination of altitude and latitude so it's not cold in summer, it is cold in winter, and winter stays between the equinoxes. And the streets are on a cardinal grid.
That does describe enough areas, and large enough areas, that for those living there it feels like "a good rule." Something they can teach their kids... and now it's not a summary anymore, but a somewhat flaky adage. Somewhat like "Moss grows on the north side of trees." I suspect that was useful somewhere... but I don't know where.
Try to make the qualifications a memorable part of your analysis, or even better, make the qualifications - the domain of the analysis - part of the story that people take away from the summary.
