The climate conditions of Krasnoarmeysky District sharply differ from those on the coast.

The Sikhote-Alin mountain range is a natural barrier which blocks the penetration of the monsoonal winds from the south and the east, forming a specific microclimate of the district.

Frosts of −40 to −42 °C (−40 to −44 °F) are very frequent in winter, while in summer the heat exceeds +30 °C (86 °F).

Despite the climate conditions, however, the population of the district grows apples, plums, cherries, and watermelons.
