Detailed explanation-1: -Tundra climates vary considerably. The most severe occur in the Arctic regions, where temperatures fluctuate from 4 °C (about 40 °F) in midsummer to –32 °C (–25 °F) during the winter months.

Detailed explanation-2: -The Arctic tundra, where the average temperature is-30 to 20 degrees Fahrenheit (-34 to-6 degrees Celsius), supports a variety of animal species, including Arctic foxes, polar bears, gray wolves, caribou, snow geese, and musk oxen.

Detailed explanation-3: -The Arctic Tundra: Located in the northern hemisphere, the arctic tundra is, quite literally, the world’s North Pole. It spans almost 20% of the earth’s surface, and is located at latitudes 55° to 70° N. It is extremely cold, and one of the world’s least populous areas.

Detailed explanation-4: -The highest temperature can get to 45° F and the coldest temperature can get to 10° F below 0. That makes it one of the coldest regions on earth. This biome feels freezing most of the year. The average precipitation per year is more than 18 inches, and most of it falls as the snow.
