Dude - VENUS does not rotate. The EARTH rotates. This is the difference between the two.

“Venus is also closer to the Sun and has a higher density atmosphere, and has virtually no water.”

That was my thinking. The higher molecular weight of CO2 relative to earths gasses is probably driving it.

As has been pointed out in the comments here, there are many differences between Earth and Venus, one of which is Venus's slow rate of rotation about its axis. A 'day' on Venus is about 243 earth days, while its year is 224 earth days.

And not only does it rotate, it does so in an opposite direction as the Earth and most if not all of the other planets.

When the year is longer than the day... that is effectively NO rotation.

Especially for the purposes of determining climate.

With the Earths 24 hour rotation, we have 12 hours of cooling after every 12 hours of heating.

Venus has over 5,800 hours of heating on a spot.

The Soviet Union’s Venera 3 was the first man-made craft to land on Venus in 1966.

Venera 3 likely dissolved in Venus' ocean—which is mostly hot sulfuric acid.

According to this article it was water vapor that initially heated Venus’s atmosphere, and it was a warming Sun that evaporated the water.

https://www.universetoday.com/22577/venus-greenhouse-effect/

Scientists think that Venus used to be more similar to Earth, with lower temperatures and even liquid water on the surface of the planet. At some point, billions of years ago, the planet started to heat up. At some point, all the water on the surface evaporated into the atmosphere. Water vapor is an even more powerful greenhouse gas than carbon dioxide and this caused temperatures to rise even more. Then the surface of Venus got so hot that the carbon trapped in rocks sublimated into the atmosphere and mixed with oxygen to form even more carbon dioxide. And so today we have a carbon dioxide atmosphere on Venus which is 92 times more dense than Earth’s atmosphere at the surface.

95% CO2 under 90x Psi of Earth Atmosphere.
Kick up our air density to 90x of existing and it would get 900 deg also.

Yet surface temps on the sun-facing side are apparently about the same as the far side.

Because...

“But those clouds are moving fast. The winds on Venus are powerful, circulating around the planet in just a matter of days. But because of Venus’ high temperatures and intense atmospheric pressure, they don’t behave like the winds on other planets.”

Our winds are not as dramatic because our planet rotates.

Yes, but it is wrong to say Venus doesn't rotate. Because if it didn't rotate the entire circumference would in time receive direct sunlight as the planet orbited the sun.

Below: imagine the blue earth in the center is the sun, and the gray moon is Venus. Red and green dots indicate a fixed position on the planet (Venus).

This is only true for the winds at higher elevations. Surface winds are weak. Only a few miles per hour.

Synchronous rotation: The moon orbit and rotation period are the same. Which is why we always see the same side of the moon. So relative to the earth, the moon has no rotation.

Venus is the essentially the orbitally same with respect to the sun.

So one side of Venus is ‘always’ being heated. The other side is ‘always’ in night. Relative to the sun, there is no rotation of Venus.

So for climate purposes ... this is very, very bad !

—————-

“The moon orbits the Earth once every 27.322 days. It also takes approximately 27 days for the moon to rotate once on its axis. As a result, the moon does not seem to be spinning but appears to observers from Earth to be keeping almost perfectly still. Scientists call this synchronous rotation.”

Gee, imagine that. Velocity decreases the closer the gas is to a fixed surface.

Why do you keep getting distracted by minutia that does not affect climate?
