Dak Nong lies on the M'Nong Highland, with an average elevation from 600m to 700m above sea level; some place is up to 1.982m (Ta Dung). Overall, Dak Nong terrain looks like two roofs of a house that line of curb roof is Nam Nung mountain chain, stretching from East to West; With an average elevation about 800 meters, some place is up to more than 1.500m. The terrain has gradual low direction from East to West. Dak Song, Dak Mil, Cư Jut and Krong Nô districts belong to the basin of Krong Nô river and Serepok river. So, it is here gradually slow from South down North. Tuy Duc district, Dak Rlap district, Dak Glong district and Gia Nghia town belong to the upstream of basin Dong Nai river. So, it is gradually slow from North down South.
Therefore, Dak Nong has diversified and abundant terrain, to be dissected strongly; there is a alternation among craggy and majestic high mountains with vast plateau. In addition, the terrain is sloppy, corugated and fairly flat alternating strips of low-lying plains. Low valley terrain; there is a slope from 0-30 mainly distributing along Krong Nô and Sêrêpok river which belong to districts such as: Cư Jut, Krong Nô. The terrain of the basalt soil plateau mainly in Dak Mil, Dak Song, with an average elevation of from 600 to 800 m, its slope is about 5-100. The terrain is strongly dissected and its slope is larger than 150mainly distributing in areas of districts: Dak Glong, Dak R'Lap.
Dak Nong is a transitional zone between two sub-climates in Central Highlands and South East; climate condition brings general characteristics of subequatorial tropical monsoon climate. There is an elevation of topography; So, it has charateristic of humid tropical highland climate; and affected by dry-hot southwest monsoon. There are two distinct seasons each year: the rainy season lasts from April to the end of November, focusing on over 90% rainfall of the whole year ; the dry season begins from December to the end of March next year, rainfall is negligible.
The annual average temperature is 22-230C; the highest temperature reaching 350C; the hottest month is in April. The lowest temperature is 140C; the coldest month is in December. The total of sunshine hours on average in year is from 2000 to 3200 hours.
The annual average rainfall is 2.513mm; the highest rainfall is 3.000mm. The wettest month is in August and September; the least rainfall is in January and February. The average air humidity is 84%; the dry season evaporation from 14.6 to 15.7 mm per day.
Prevailing wind direction in the rainy season is southwest; Prevailing wind direction in the dry season is northeast; the average wind speed from 1.5-5.4 m per second; it's almost no storm so that it doesn't affect socio - economic development.
However, unfavorable climate is imbalance of rainfall in year and great fluctuation in heat amplitude of day-night and seasonal temperature. So, decided factors in producing and living are to supply water, preserve water and layout seasonal crops.
Dak Nong has a system of rivers, lakes, dams which are evenly distributed. These are favorable conditions for exploiting water resources serving agricultural production, industry, construction of the hydroelectric projects and serving local resident's demand.

+ Serepok river is combined by two branches of confluence river Krong Nô and Krong Ana crossing-over at Buon Dray waterfall. When flowing through the territory of Cu Jut district in Dak Nong province. Due to the complicated geologic tectonics, the river-bed becomes narrow and sloppy creating majestic big waterfalls; Serepok river has both beautiful natural scenery and hydroelectric potential bringing economic value such as: Trinh Nu waterfall, Dray H'Linh waterfall, Gia Long waterfall, Dray Sap waterfall. The Dak Gang, Dak Nir, Dray H'Linh, Ea Tour, Dak Ken, Dak Klou and Dak Sor streams are also the upstream of Serepok river.
