I must be using the tool wrong because literally everywhere in the US is my Goldilocks zone which I'm certain is not the case. I set it to give me places where the minimum winter temperature is -5°C (23F) and max summer temperature is 35°C (95F) and every part of the map is coloured purple.
I think I just don't understand what to input to give the answer I want. I entered the typical minimum and maximum temperatures that I experience where I live now which is London, UK. Given that, I wouldn't expect the tool to tell me that the entire US has the same climate as London. I think it's because I'm used to a place where the extremes only last for a few days in each year and the rest of the time the temperature is pretty mild. Tolerating a 35°C day in the summer is not that hard when it only happens once every 5 years and you can go and drink cold drinks in the park.
I think it would be interesting to see the same map of the US but showing areas that never reach above or below the limits that you set.
You could probably pick a summer month in the month drop-down, at least for a pretty good approximation of 'areas that never go over X temperature,' since purple indicates 25-31 days inside your range.
This told me that I should live in Alaska, or on Mt. Washington. Unfortunately my ancestors came from your cloudy islands and we never adapted to all this horrible sunlight I guess.
