In the early days of science fiction, the one thing most people knew about the planet Venus (or rather, most people who knew anything about Venus or any other planet in our Solar System for that matter, which at the time included only a very limited group of enthusiasts with university education) was that it has permanent cloud cover over its entire surface. This led to many depictions of Venus as a planet where it rains a lot, often to the point where it's a Single-Biome Planet covered in oceans, or at least swamps or rainforests. In the 1960s, the planet was visited by unmanned probes which definitively established that the clouds were sulfuric acid, the atmosphere was largely carbon dioxide, and that due to the resulting greenhouse effect the temperature at the planet's dry and barren surface was nearly 900 degrees Fahrenheit (480°C). As a result, this is now a Dead Horse Trope used only by authors deliberately harking back to the old days, or in works involving terraforming. Some new evidence suggests, however, that Venus did once have water and could have been habitable as recently as around 700 million years ago, but then something went wrong (most likely involving its volcanic system)note creating a runaway greenhouse effect and as a result, the oceans either boiled away or were superseded by lava long before they could. Compare Once-Green Mars.

- Subverted in Cowboy Bebop. While Venus has been terraformed to the point where people can live there, the surface is still a vast desert. However, numerous floating islands composed of tropical plants were constructed and serve as both a method for introducing oxygen and home for the colonists. Which, incidentally, is the most realistic way Venus could be colonized.
- Core Line: One of the various reality changes done by the Vanishing was the transformation of Venus into a jungle planet out of pulp fiction, inhabited by characters from the same... and a hard-core Death World nasty enough that any kind of Nature Hero that lives there (well away from civilization) is astonishingly superhuman.
- Poul Anderson: In "Sister Planet" Venus is an ocean world with no landmasses. In a variation from the norm, it doesn't have a human-breathable atmosphere.
- Isaac Asimov: In Lucky Starr and the Oceans of Venus Venus is an ocean planet with seas and kelp (and domed underwater cities).
- Ray Bradbury:
- "All Summer in a Day" is set in a colony on Venus, where it rains continually and the sun comes out for only an hour once every seven years.
- In "The Long Rain", a rocket crashes on Venus, where it rains constantly. The crew must locate a Sun Dome in which they can find shelter, or die.
It was a hard rain, a perpetual rain, a sweating and steaming rain; it was a mizzle, a downpour, a fountain, a whipping in the eyes, an undertow at the ankles; it was a rain to drown all rains and the memory of rains.
