All such planets orbiting so close to their star are certainly tidally locked.

Even Venus is almost tidally locked, tens of millions of miles away from the sun. All moons in our solar system are locked. It is the norm.

Thanks. TIL.

I have read a science fiction story or two set on tidally locked planets, and the humans occupy the slim twilight belt between the hemispheres facing towards and away from the sun, where the temperatures are less extreme.

If it has an atmosphere, though, I imagine its expansion and compression cycle would make it quite stormy.

Given the negligible variation in energy input to various parts of the planet, over time, I would expect it to be fatally placid.
