Weather conditions: |
| The winter was characterised by frequent, large snowfalls, especially in the forest-tundra, mountains and southern parts of the tundra, where the last snow fell on the 20 June. The snow melted slowly, with many snow patches still remaining in mid-August. Summer was cold, with rain and wind.

Breeding conditions:
|
| There were extremely low numbers of mosquitoes. Arctic Foxes probably did not reproduce at all and were moving long distances. Rough-legged Buzzards and skuas (particularly Pomarine Skua and Arctic Skua Stercorarius parasiticus) were scarce, occurring mainly in river valleys. None of the twenty Rough-legged Buzzard nests that were found contained eggs. Ruff, Wood Sandpiper, Temminck's Stint, Common Snipe, Pintail Snipe and Spotted Redshank Tringa erythropus all bred in large numbers. However, wader breeding success was not high due to summer flooding and unfavourable weather conditions. Waders started autumn migration at least five to seven days earlier than usual.
