Don't you live in a generally warm country? I thought the temp was over 75 degrees even at night... 
haha cliches...
no, I live in Buenos Aires and here you have pretty much all temperatures.
in summer: from dec 21 to march 21 the normal temp is around 30-33 but we have killer days of 40-45 degrees.
in spring: from sep 21 to dec 21 the normal temp is around 17-20 degrees
in autumn from mar 21 to jul 21 the normal temp is around 17-20 too
in winter: from jul 21 to sept 21 the normal temp is around 5 degrees, but we have those freezing days of 2 degrees, -2 degrees. and once it even snowed in the city, which was considered as a fucked up event due to climate change.
all in all, summers are really really hot, but winters can be just as cold as the ones in New York or in England
