Well it's about 24 degrees Celsius (76f) right now. I'm in the Southern Hemisphere, so it's mid nearly late Autumn right now. I'm living in Australia this year, I'm not used to this heat.
Where I come from, it's currently 11 degrees Celsius, (50f) according to Google.
Also Hayden, I think you got that conversion wrong. 18 degrees Celsius is 65f. 40f is only five Celsius degrees above freezing point.
