This is a list of Half-Life: Alyx skies, along with pictures of each skybox. Sun Angle, Color, Brightness, Indirect Light Multiplier, Sky Color, Sky Intensity, Sky IBL Scale, and Skybox Bounce Multiplier are all settings found in the light_environment of the map referenced in Example Map

Skybox Material is the name of the skybox vmat used by the env_sky of the map referenced in Example Map. Image shown does not necessarily represent actual skybox but is the image found using Source 2 Viewer and decompiling the VTEX.

For most of the example maps, the env_sky is used as the Sky IBL Source inside of the light_environment which is then used to "Estimate Lighting from HDR Skybox" (Done by Right Clicking the light_environment, and going to Selected Entities>Estimate Lighting from HDR Skybox)

Note:Estimate Lighting from HDR Skybox requires the source files of the given skybox

For more information on the light_environment entity in HL: Alyx as well as the env_sky entity, please visit the Source 2 Lighting Page

Warning: The images on this page only show the skybox sides (left, right, front, back). Skyboxes have much more detail on the top, which may not be accurately reflected on this page; view the skybox in-game or in Hammer to get a better idea of how a sky looks.
