here in brazil 20° is cold, 25°C is great, 30° is a normal day. 35° beach time
if it gets bellow 20° i don't even go outside without a coat. 15° we're all dead frozen i suppose, cause ive never felt that temperature in my town.
We get some summers in AU where it's we have temperatures above 35+. It's fucked and people who come from colder countries can't handle it. Sometimes we even get successive days with 40+ degree maximums.
