When Does The Low Temperature Usually Occur?

Hello -- it is Chris -- back from sunny and very warm south Florida. A cold front did go through on Sunday and man was it windy down there. I have never seen such constant wind. Sustained 20-30 for 2 days.

I can only imagine what a full blown tropical storm or hurricane must be like. Even with just 20-30 mph winds there was some costal flooding and beach erosion, as well as downed trees and debris.

The pool cushions on the chairs around the pool at the resort were all over, one was on the bottom of the pool!

While I was away, a few people left comments talking about the coldest part of the day -- and how they have observed it is often just after sunrise.

Assuming it is just a normal day with normal weather, no cold fronts, extremely windy situations, etc. then the maximum cooling typically takes place at or after sunrise.

Even though the sun may have risen over the horizon, it takes a while for the sun's rays to overcome the radiational cooling that took place all night -- so despite the sunrise, the temperature continues to fall.

Once the sun's rays are strong enough, and overcomes the escape of heat from the Earth back out into space, the temperature reverses and begins to rise.
