Weather conditions: |
| Ice broke on the Anabar River on 5 June, and flood was high. Tundra became 60% free from snow by 7 June, but snow cover re-established on 9 June, and reduced to 10-20% by 15 June. Larch greening started by 20 June. Ice on large lakes melted in early July, and snow patches remained until 5 July. Summer was dry and warm, and areas to the south were affected for fires during 2-3 weeks.

Breeding conditions:

Arctic Foxes bred. Wolves and wolverines were not rare. Rough-legged Buzzards and Peregrine Falcons sucessfully nested every 3-5 km. Among skuas only Long-tailed was common. Pair Gyrfalcons and pair of White-tailed Sea Eagle bred near the village.
Ringed Plover, Temminck's Stint and Common Snipe were common in floodplain, while Wood Sandpiper and Ruff were common locally. Pacific Golden Plover and Grey Plover nested in dry tundra, while Grey Phalarope, Ruff and Bar-tailed Godwit occurred in lowlands. Swans were rare. Bean Goose was common among geese, and migrated from 24-30 May. Red-breasted Goose was rare. Common Scoter, Pintail and Long-tailed Duck migrated to the south in small flocks by 20 June. Common and Herring gulls and Arctic Tern were common breeders on lakes. Grouse were common and bred. Pied and Yellow wagtails, Red-throated Pipit, Snow and Little buntings, Redpol were the most common among passerines.
The area was visited during summer by 4-5 large flocks of migrating wild reindeers, which followed waterbodies and trampled bird nests and chicks. Wader numbers did not differ considerably compared with the previous year, while reproductive success was below average.

Rodent dynamics:
|
| Heavy crop of bog bilberry and crowberry stimulated increase of lemming and vole populations. Rodents were frequently seen, and also were seen their tracks. Numbers of mountain hare were increasing.
