I work outside a lot in the summer at many different locations. Take that Boot Hill of Missouri and draw a line west to east.

Yeah I can see that if you are right on the water. But I find it much tougher in New Orleans as opposed to Bham this time of year. And in winter Bham is often a helluva lot colder.

shite, I spent a few days in Ridgeland, MS for work back in June. The humidity was noticeably less than BR, had a nice breeze and the late afternoon was downright pleasant.

Any sane person who has spent any time in these cities would have to agree.

Honestly, it happens a little north of I-10 in Louisiana. We actually have more days over 95 in North Louisiana than South Louisiana. This is because the Gulfstream keeps humidity higher, which limits air temperature.

A little North of 1-10. You mean the climate changes in Arkansas?

I can tell you that North AL can be just as miserably humid as the Gulf area and it is capable of higher temps on the extreme end of the spectrum.

Lake Charles and Shreveport are almost in a straight line North to South and they have very different climates

I feel like it depends on the season. Parts of Arkansas/Tennessee can see regular snows in the winter but in the summer its all hot. I'll let yall debate slight differences in humidity

150-200 miles north of the gulf coast will start to see humidity levels drop. That’s the line where climate starts to change.


You might want to add a zero to those numbers.

i think things change every 3 hours of drive time, or about 200 miles.

Thats USDA growing zones for plants. More of a guide for how cold the lowest winter temps typically so you aren’t planting stuff in your garden that’ll end up guaranteed to not make it through the winter. Not necessarily relevant to the summer heat because the central US plains are regularly in the low 100’s while the gulf coast is in the low-mid 90’s. Heat index ends up being fairly close with the coastal humidity.

Tennessee / the point is not that Memphis is hotter than Mobile on any given day in the summer. The point is Tennessee cools down in September. New Orleans cools down 6-8 weeks later.
Tennessee has 4 distinct seasons. Gulf coast states do not.

I beg to differ. The humidity in Shreveport or in northern Mississippi is every bit as oppressive as near the coast, maybe moreso as the breeze that far inland tends to be non-existent, not comforting as nearer the coast. Shreveport LA has probably the worst combination of heat, humidity and still air of any city in America during June to August. You can cut the air with a knife!

To their advantage, however, they do get cool fronts earlier in fall and later in spring than coastal areas, but the spring fronts are often mixed in with severe weather.

In Alabama I would say the Tennessee Valley area. That is only marginally better and in the higher elevations. They tend to get in on the early “cold fronts” that tend to peter out before reaching the coast.
They definitely get more frozen precipitation than we do in Bham.
