Mass Effect 2[]

  • Surface Temperature: 34 Celsius (temperate zone)

With over 90% of its surface covered in oceans, Yamm is a habitable nitrogen-oxygen world but its extremes can be quite hostile to sapient life. The heat from its extremely long days reaches dangerous levels, ranging from 44 Celsius at night to 53 in the afternoon in the temperate zones. Hurricanes run unchecked across the oceans, with winds reaching up to 250 km per hour.

While there are some arthropod-like animals, the predominant forms of life are various kinds of toxic algae blooms that stretch hundreds of kilometers cross. However, other biohydrocarbon algae blooms are suitable for use as biofuel, and farming the "green gold" forms the backbone of Yamm's economy.
