The tundra has two main seasons.

During the cold season, winter, which lasts from late fall through winter, and into early spring. The temperatures during the cold season is around 18 F, 28 C, below zero, and it can be dark for much of the cold season without any daylight, depending on how close you are to one of the poles.

In the warm season, summer, temperatures are around 12 C, 54 F. This isn't warm enough to thaw the permafrost layer, however. During the summer, plants like lichens, small berries, grasses, and moss can grow. And because the tundra is so close to the poles, for a portion of summer there is 24 hour daylight for several weeks.

Briefly during the summer period, temperatures warm up to a maximum of 10 degrees Celsius (which is still very cool) and there is a small amount of rainfall; the snow and ice on the ground also melt. You will also see ground vegetation (shrubs, herbs and mosses) emerging. There are long periods of sunlight in the spring (if there is a spring) and summer (in the summer, it is daytime for 24 hours).

Outside of summer, especially in winter, the temperature dips below freezing, there is only snowfall (or no precipitation at all), and there is little to no vegetation. In autumn (if there is an autumn) and winter, it is dark most of the time....
