Here you can find information on the climate of the Tundra. The winter temperatures average about -30 F throughout most of the true Arctic including the North Pole. The coldest weather occurs in northeastern Siberia. The warmest summers occur in the inland regions of Siberia, Alaska, and Canada. July temperatures there average around 60 F. Weather stations have recorded temperatures of 90 F and above in these regions.
Winter storms develop chiefly in two areas where the barometric pressures remains low.
One of these areas, called the Aleutian low, extends from eastern Siberia to the Gulf of Alaska. The other, the Icelandic low, covers central Canada, half of the Arctic Ocean, and parts of the North Atlantic Ocean and northern Europe. Storms beginning in these areas tend to travel from northwest to southwest. Rainfall in many arctic regions totals six to ten inches a year, including melted snow. Much of the arctic has rain and fog in the summer.
