Hotlanta ... really?

Which is hotter:

Naples or Atlanta?

If you go by the 80° F standard, Naples broke that plane for the better part of 7 months ...

Compared to only 3 for Atlanta.


On the winter side of the scale, Atlanta gets a true "season's worth" of continental cold air (that sends weekly-averaged night-time lows below 32° F).

Only rarely – once or twice per year, and sometimes none – do night-time temperatures in Naples break that plane.


That begs the question:

Why "Hotlanta" and not "Coolanta" instead?


For one its a name attributed to its "social" climate, just not meteorological.

Second, Atlanta is land locked:
it doesn't have a sea breeze ...

Nor does it have Florida's ubiquitous afternoon cloud cover nor its regular late-day wet chill of cumulonimbus showers.


That makes Atlanta seem hot (and humid) even by south Florida standards.

The "Hotlanta" moniker always makes me feel old. I'd go to a Braves game, but I don't think baseball is what makes Atlanta "hot."

Interesting climatic comparison!

Hi Bob:

I bet that Atlanta does not just 'seem hot' compared to south Florida. In West Palm Beach I think the maximum temperature ever recorded is 96F. If you use 95F as a cut off plane I guess that Atlanta would not just seem hot.

When we gloat about south Florida's wonderful weather, folks often ask whether we have been here in summer. And I remind them that lots of place in eastern United States often have bouts of very hot weather, even over 100F, every summer. And no breeze or afternoon thunderstorms as you point out.

A corollary of our peninsula and sea breezes is what may be the best air quality in the United States. In south Florida we have no coal-fired power plants and any air pollution is blown out to the Atlantic or the Gulf by continually shifting weather systems.

Really great points. That's a good idea to look at 95° F exceedences. Even allergy season has been good to me this year (talking about air quality).

Holland (i don't mean Hotlanta) was cold! I am glad to be back in the warm Yukon. Warm, even hot out of the wind in the sun, indeed even if temperatures don't show it.
