In the Overworld, clouds appear at layer 127. They help with direction and are merely aesthetically pleasing. They always float in the same direction - towards the west - making it easy to use them to get the player's bearings.
 Fancy graphics
On fancy graphics, clouds appear as about four block tall semi-transparent prisms. In the nighttime they turn a shade of blue and become more transparent. Their smallest horizontal dimensions are 12×12 blocks wide. They are similar in appearance to the real life cloud species stratocumulus.
 Fast graphics
On fast graphics, clouds appear as opaque planes. They have no daytime/nighttime rotation. Their smallest horizontal dimensions are 8×8 blocks wide.
Unlike many things in Minecraft, clouds are not procedurally generated. With a texture pack, clouds' color can be changed to anything, meaning you could have pink clouds if you so desired. The file can be resized to any size, meaning it would be possible to have a different cloud pattern each day.
|1.8||Prior to this update, clouds existed between layers 108 and 112, floating through anything in those layers and obscuring the player's view should he/she be inside them.|
|1.9pre4||Clouds now float towards the west. Before this, they floated north.|
|1.9pre5||Clouds can now be disabled in the Video Options menu.|
|1.2.1||Build height increased to 256, allowing for players to build much further above clouds.|
|Pocket Edition Alpha|
|0.6.0||Added clouds. Clouds can only be seen in Fancy graphics, and if so, the clouds will appear opaque and 2-dimensional in similar to fast graphics.|
|Pocket Edition 0.8.0||3-D clouds added.|
Issues relating to "Clouds" or "Cloud" are maintained on Mojira. Report issues there.
- If you switch between fast graphics and fancy graphics, clouds will be in a different place than they were before.
- Clouds are a client-side feature. On an SMP server, the position of clouds is subjective to each individual user, and are not generated server-side.
- In Infdev, clouds had a texture instead of being completely white.
- In Pocket Edition, clouds are completely flat and 1 pixel thick.
- If a cloud floats through an enclosed area, (e.x. a sky home with a roof) and the sun is above the cloud, you can see the sun through the cloud and roof.
- On Fancy graphics, where clouds are 3-dimensional, signs inside a cloud will be invisible on the outside.
- Clouds are not interactive in any form.
- Rain is generated above Clouds
