Moscow time+2 (Yekaterinburg time)

Nizhnevartovsk, like the entire district, is located in the Moscow time zone+2 (Yekaterinburg time). The offset of the applied time relative to UTC is +5: 00[13]

The main watercourse of the city is the Ob river, from the mouth of the Svitlaya Bayou to the Lokosovskaya Bayou. Within the Nizhnevartovsky district, the section of the middle Ob river is 134 km long and the floodplain is 18 to 20 km wide. By the nature of the water regime, it belongs to the type of rivers with spring and summer floods and floods in the warm period of the year. The duration of the flood is on average 60–130 days. The appearance of ice formations on rivers is typical for the second half of October—early November. The average duration of ice build-up is 180–200 days. In hydrographic terms, the taiga zone of the Ob river differs sharply from the forest-steppe zone adjacent to it from the South; this difference is primarily due to a change in the ratio of water balance elements. With a noticeable increase in precipitation, with a decrease in their losses to evaporation, surface runoff increases sharply here.

In 2015, the largest flooding of territories adjacent to Nizhnevartovsk in thirty years occurred, including numerous dachas and gardening associations. The reason for the dynamics of water level rise was the climatic features of the spring period.[14]

Nizhnevartovsk is located in the continental climate zone. The climate is characterized by a long winter, long snow cover (200–210 days), short transitional seasons, late spring and early autumn frosts, short frost-free period (100–110 days), and short summer (10–14 weeks). Winter is characterized by significant inter-day variability in air temperature, the average value of which is 5 °C.

The annual precipitation rate is of the continental type. During the cold period, about 20% of the annual amount falls. Most of them fall in the first months of winter. The maximum annual precipitation falls in the summer months of the year — from June to August. In some years, the amount of precipitation may deviate significantly from the norm. The annual minimum precipitation is observed in February. Snow cover is formed in October—early November, and its descent is observed in late April-early may.

As the entire district is equated to the regions of the Far North.

• Average annual air temperature: −0.9 °C
• Relative humidity: 73.7 %
• Average wind speed: 3.1 m/s

In the Nizhnevartovsky district, as well as throughout the entire territory of the Middle Ob region, cedar (people in Russia called "cedar" some species of pine, in this case – Siberian pine) forests are indigenous, and birch and aspen trees that have arisen in their place are derived. The basis of the district's forests is made up of three species: pine, cedar and birch. Among the forest formations, the area is dominated by pine trees. Cedar forests cover less than a quarter of the forested area. A third of the area is occupied by small-leaved forests.

Pine trees are found on sandy and sandy loam strongly podzolic soils and are confined to elevated terrain areas. The most common types are lichen and cranberry pines.

For cedar trees, a good development of the grass-shrub layer is characteristic, in which the dominant value belongs to forest shrubs (blueberries, cranberries, watermelons, marsh bagulnik) and taiga smallgrass (Linnea Severnaya, kislitsa, maynik dvulistnogo). Shrubs are represented by Siberian mountain ash, individual specimens. Green mosses are always present in these forests.[15]
