December in Niger marks the full onset of the hot dry season, with significantly reduced rainfall and consistently high temperatures. Average temperatures during this month range from 20°C (68°F) to 30°C (86°F).

However, the weather during this month is still much cooler than during the peak of the hot dry season, which occurs in the first half of the year.

Rainfall in December is virtually non-existent across the country, with both the southern and northern regions remaining dry. The lack of rainfall, coupled with the high evaporation rates, further exacerbates Niger's overall water deficit.

Niamey, the capital city, sees a continuation of the hot dry season in December, with average temperatures ranging from 19°C (66.2°F) to 29°C (84.2°F). The absence of rainfall, combined with the consistently high temperatures, underscores the dominance of the dry season in the city's climate.

Daylight hours in December remain constant, with an average of 11 to 12 hours of daylight per day. The month is characterized by clear skies, high temperatures, and low humidity levels, reflecting the hot dry season's progression. The dusty and hazy conditions associated with the Harmattan winds reach their peak, providing a distinct characteristic to December's weather. The arid conditions and high temperatures in December set the stage for the continued dominance of the hot dry season in the upcoming months.
