Recurring seasons (зимами, вёснами)

The Instrumental Plural for Recurring Seasons

To say something happens "in the winter" or "during spring", Russian uses the instrumental singular (e.g., зимой, весной). But to describe cyclical events that repeat year after year—such as animal migrations or natural rhythms—you can use the bare instrumental plural of the season.

SeasonInstrumental SingularInstrumental Plural
зимазимой (in winter)зимами (in winters)
веснавесной (in spring)вёснами (in springs)
осеньосенью (in autumn)осенями (in autumns)

While you could say каждую зиму (every winter), using forms like зимами gives your speech a natural, traditional, or slightly poetic tone, making it perfect for describing the cycles of nature.

Notice how it pairs with vocabulary for habitual events, like bears falling into hibernation (спячка).

In winters, all bears fall into hibernation.
Зимами все медведи впадают в спячку.
In winters, our rivers freeze and become covered with ice.
Зимами наши реки замерзают и покрываются льдом.

Autumn and Spring Cycles

The same pattern applies to the transitional seasons. We use осенями and вёснами to describe the habits of migratory (перелётный) birds setting off (отправляться) south and returning to nest (гнездиться).

The Arrival of the Seasons

When talking about a season "arriving" or "setting in", Russian uses the verb наступать. This often sets the stage for discussing how animals survive (выживать) harsh conditions by finding food (пища).

In winters, they survive by getting food from under the snow.
Зимами они выживают, доставая пищу из-под снега.

Emphasizing the Timing

To emphasize that a natural event happens in one specific season and not another, you can place focus words like именно (precisely) or как раз (exactly) right before the instrumental plural noun.

Precisely in autumns, bears look for food, preparing for hibernation.
Именно осенями медведи ищут пищу, готовясь к спячке.
