The Arctic tundra is famous for being the coldest of all the biomes. Bitter temperatures and windy conditions dominate the region. Its climate boasts average temperatures that are below freezing! Climate is the average weather over a long period of time. When we look at a biome’s climate, we are looking at the average temperature and temperature ranges as well as precipitation and how it varies throughout the year. In addition, sunlight, humidity, wind and other factors are taken into consideration when describing a region’s climate.
There are basically two seasons in the tundra - summer and winter. Both are quite dry with minimal precipitation falling. Winters may last up to 10 months of the year when it’s common to have temperatures below freezing and some snowfall. Summers last only a few months at best and boast temperatures in the 50’s with both sunny and rainy days occurring. With summer snowmelt creating temporary bogs and ponds, water may evaporate and cause cloudy days toward the end of the season. Even though there is technically a summer season in the tundra, snow and frosty conditions are possible at any time of year. In far northern sections of the tundra, there are even days where the Sun never rises and darkness prevails due to the latitude being close to the polar regions.
