that's not even 80 degrees fahrenheit! that's hot but not THAT bad!
right now it's only about 19C (65 F) but that's because it's been rainy lately. we easily get upwards of 90F (32/33C) in july/august.

my personal preference is between 40 and 55 F (4C to 13C)

i'm having too much fun with the google convserion calculator
