Try Galveston in late July and August. Doesn't drop below 75F (avg low is 80F). Pretty much same dew points too.

Same as me from June till Oct. I avg around 76 to 79f most nites since i am right on the gulf. Sometimes i will see a 72 or 73 if we had strong T- storms with high tops the nite before. And sometimes i see a low of 82 to 84f. Just open the door at 530am and the life is sucked out of ya.

I am not in Tampa. I am right on the gulf northwest of Tampa 28 miles and when we are in a reverse west windflow with the wind blowing off of 90 degree gulf temps 24/7 it is a steam bath from hell. When we have a east flow in the summer it knocks the dew points down to around 72 to 74f.

Hey LKJ, could you make a Paint drawing describing how a reverse west windflow works, because I've no clue

Ya easy to do. Be back soon. SO EASY TO UNDERSTAND FOLKS. As seen in the pic with the axis of the high north of Tampa we get a southeast windflow and that was the normal summertime pattern in the 50's thru the 70's. Then in the mid 80's the high has been pushed well to the south of the Tampa area that we get a southwest or west wind all day and nite. So our summer rains all depend on where the high it placed.

Concrete retains heat
Houston has massive amounts of concrete, tall buildings that both block winds and retain heat on all sides of their mass
It is a heat sink...
Even in cooler weather concrete, roadways/streets, just about all of Houston and the surrounding areas draw and retain heat...

In my TX area...DFW...we have the same phenomena
Nights used to cool,off in summer...heat would dissipate

Not so now
As the concrete mass as grown, nights are warmer...
A daytime high of 95-100 means it can be over 90 at midnight...say hot all night vs cooling
IMO as the concrete infrastructure has taken over ground/large tree canopies the residual heat has become a part of weather cycle...

Ok, but New Orleans uses tons of asphalt to pave their roads (asphalt retains heat even more).

At one point in the 80s Houston was the most air-conditioned place on earth. Maybe that contributed to the heat outside.

It seems like Austin is hotter than Houston now.

And look at how much has been built since 50 years ago. No wonder temps keep coming up.

Only problem is, New Orleans is also urban. Mobile is also urban. But they still don't have the same high temps as Houston. New Orleans has summer lows just as high as Houston, despite their summer highs being slightly lower. New Orleans has less of a diurnal variation than even Houston.
