I chuckled at this. Ignoring factors like humidity, rain, wind, and number of sunny days gives you a very distorted vision of the weather in a given place.
I love Ireland but couldn't live there full time.
There are many reasons not to live in Dublin (poor housing quality / price, high cost of living, poor public transport, crime, etc) but the weather is absolutely not on that list.
Dublin has about 130 rainfall days each year, and most of those are in the winter. Most days are mild and dry. The weather is warm and pleasant enough to enjoy water sports year-round. I spend most of my recreation time during the winter in a wetsuit without a hood.
We don't get heavy snow, extreme cold/heat, hurricane force winds, or flooding. Overall, I think the weather here is better than most people give it credit for.
the weather, even when it's not rainy, it's ofter miserable, with very low overcast that gives us southerner an unredeemable sense of oppression.
> hurricane force winds
my worst landing ever were all clustered around the dublin airport. gusts up to 100/130 aren't as uncommon as you make it to be.
and all the people I knew that indulged in water sport did so with thick wetsuites
I was kind of surprised to see poor public transport on your list as it's a major European city. Is this true of the whole city or just certain parts?
the public transit services also disappears for almost all intended purposes at night, which is weird for a very international capital with such a vibrant night life. and taxis often refuse courses outside the inner city, albeit that has been changing with ubers and whatnot.

I'm quite surprised Quito (capital of Ecuador) didn't come up however: it's near the Equator, so constant temperatures, and at very high altitude, which reduces the temperature to pleasant levels (https://en.wikipedia.org/wiki/Quito#Climate).
Toronto is right on Lake Ontario which, at least for the old city, moderates weather a lot compared to just 100-200 km north of the city. Things can change quite a bit by the time you get to Lake Simcoe, or to the west (Guelph-London-Owne Sound triangle).
The methodology is very clearly flawed; maybe amusing as a programming exercise, but of no value in determining where one wants to live.
As a New Yorker, I personally like some variation of the seasons, but I guess if I lived in Medellin I could always head up to the Caribbean coast for some beach weather.
