Current weather readings and forecasts are rounded off to the closest
degree C. I defy you to identify a one degree F difference in temperature.

That depends on what you are used to. Around here, 100 F (38F) is all but
unheard of, and most people consider 35C to be really bloody hot, but if
you want to deal with convenient references you could make it 40C being the
indicator of really bloody hot. The convenient thing about the freezing
point being 0C is that, due to the heat exchange involved in change of
state of water, water to ice or ice to water, the freezing point makes a
major difference in the climate and its effect on a person. Accordingly,
using that point for 0 makes sense. It's above freezing or below freezing,
A positive or negative reading, rather than having at it 32.
