Following this peak, the rainfall begins to taper off slightly in September and October, though totals remain significant at 176 mm (6.9 in) and 170 mm (6.7 in). As the rainy season concludes in November with 73 mm (2.9 in), the region winds down towards the drier months of December, which sees a steep drop to 29 mm (1.2 in). The number of rainy days mirrors this pattern, increasing from just 1 day in January to a maximum of 21 days in August, demonstrating a strong relationship between the seasonal distribution of rainfall and agricultural cycles in the region.
In the Northern Region of Uganda, sunshine duration exhibits a notable seasonal trend characterized by a gradual increase during the early months of the year. January begins with 280 hours of sunshine, which rises steadily through February to reach 312 hours. By March, sunshine peaks at 342 hours, marking the transition toward the warmer months ahead. This period is optimal for sunlight exposure, benefiting both agriculture and the local populace who rely on sunlight for various activities. Although sunshine hours slightly decline in April to 323 hours, the region maintains a strong average throughout the rainy season, with May recording 337 hours of bright days, ensuring an abundant and productive period for crop growth.
As the region moves into the latter half of the year, sunshine hours remain consistent, with July and August showcasing impressive totals of 335 hours and 342 hours, respectively. September follows closely with 334 hours, while October and November maintain this trend with 338 hours and 331 hours, respectively. Notably, December stands out as the month receiving the highest sunshine duration at 345 hours, indicating a remarkable end to the year and signaling the return of sunnier days. This consistent pattern of abundant sunlight, particularly in the last quarter of the year, highlights the region's favorable climate for agriculture and encourages year-round outdoor activities, further supporting the community's economic and social well-being.
The UV Index in the Northern Region of Uganda highlights an alarming trend of extreme levels of ultraviolet radiation throughout the year. Starting in January, the UV Index registers at 15, indicating an extreme exposure category, with a recommended burn time of just 10 minutes for unprotected skin. This extreme level persists as the months progress, peaking in March at 17 before slightly declining to 14 in May.
