Voted 55 - 75 degrees Fahrenheit. I guess it depends on the humidity mostly; if it is humid I would prefer if it were colder and vice versa. In general, I love cold winter days more than I do hot summer days.
I'd say 18?C – 24?C. I do not enjoy temperatures above 24? C, it becomes too sweltering for me.
I can withstand cooler weather though, I'll just do a lot of layering.
I picked 45-65 Fahrenheit. My favorite temperature is what I like to call "hoodie weather", and I generally prefer to be cooler anyways. Anything beyond 70 is usually too hot for me.
