North-West Botswana experiences a BSh climate classification, characterized by semi-arid conditions that shape its unique weather patterns. The region showcases a significant temperature range, with a minimum of 1°C (33°F) recorded in July, the height of winter, while average temperatures hover around 23°C (74°F). This region can also experience extreme heat, particularly in November, where maximum temperatures can soar to 41°C (107°F). Such climatic extremes influence both the local ecosystem and the lifestyles of the inhabitants in this diverse part of Africa.
In North-West Botswana, temperature patterns reveal a distinct seasonal cycle characterized by a notable contrast between the warmer and cooler months. From January to March, temperatures remain relatively high, with minimums ranging from 15°C to 16°C and average highs peaking at 40°C (104°F) in January. As the region transitions into April and May, temperatures begin to cool, reaching minimums of 11°C and 3°C, while averages dip to around 20°C (68°F) by May. The peak of winter occurs in July, marked by the lowest temperatures, including a minimum of 1°C (33°F) and an average of 17°C (63°F). As the winter months give way to spring, temperatures gradually rise again, culminating in November where maximums reach 41°C (107°F), indicating a hot end to the year. This fluctuation not only influences the local climate but also significantly impacts the ecology and agricultural practices in the region.
Maun experiences a significant temperature range throughout the year, with a minimum of 1°C (34°F) in July and a maximum of 41°C (105°F) in October. This variation highlights the extreme climate conditions that can be faced in the region. For a detailed look at the monthly temperatures in Maun, visit monthly temperatures in Maun.
North-West Botswana experiences a pronounced wet season from January to March, with precipitation peaking in February at 193 mm (7.6 in), followed closely by January with 176 mm (6.9 in). This time frame typically sees a higher frequency of rainfall, averaging 16 to 19 days of precipitation each month, contributing significantly to the region's water resources. By March, rainfall begins to decline dramatically, dropping to 80 mm (3.1 in), a trend that continues into April where only 23 mm (0.9 in) is recorded over just three days of rain.
As the dry season unfolds from May through September, precipitation dwindles to minimal amounts, with May and the subsequent months often recording no significant rainfall at all. This absence of rain continues through August and September, with October marking a slight uptick at 8 mm (0.3 in). The onset of the wetter conditions returns in November, where 41 mm (1.6 in) is recorded over seven days. December reinstates the rainy season with 99 mm (3.9 in), setting the stage for another cycle of heavy rainfall and rejuvenation of the landscape as the year concludes.
In North-West Botswana, sunshine duration exhibits a clear seasonal trend, with the months of October, November, and December boasting the highest levels of sunlight. December stands out as the pinnacle of sunshine, recording 366 hours, closely followed by November at 363 hours. This rise in sunshine hours from late spring through summer aligns with the region's transition into the warmer months, providing ample daylight for both natural ecosystems and agricultural activities. The increasing hours of sunlight during these months not only enhance the region's biodiversity but also boost the overall warmth, contributing to the semi-arid climate.
Conversely, as the year begins with the cooler months of January and February, sunshine duration is somewhat lower, with 286 hours and 288 hours, respectively. However, even during these months, the sunshine builds steadily, peaking in March at 343 hours before gradually tapering off in April. Despite the cooler temperatures of winter, sunshine remains relatively consistent, with 313 to 332 hours recorded from June through September. This consistency in sunlight during the cooler months underscores North-West Botswana's unique climate dynamics, a characteristic that shapes the region's ecology and the lifestyles of its inhabitants throughout the year.
The UV Index in North-West Botswana reflects a significant seasonal variation, particularly highlighting the extreme levels of ultraviolet radiation from January to April. During these months, the UV Index peaks at 17 in January and remains above 14 through March, categorizing the exposure as extreme and resulting in a burn time of just 10 minutes. This intensity demands strict sun protection measures for residents and visitors alike, as prolonged exposure can lead to severe skin damage. Awareness of these conditions is essential for outdoor activities, especially during the height of summer when the sun’s rays are most potent.
As the year progresses into May and June, the UV Index experiences a slight decline, dropping to 10 and 8 respectively, shifting to a very high exposure category with a burn time of 15 minutes. Although still significant, the risk of harm from UV exposure decreases slightly during these cooler months, with the index occasionally rising again in August at 10. In September and October, the index returns to the extreme category with values of 12 and 13, suggesting ongoing caution is needed. Notably, November and December see a resurgence of the extreme levels at 15, reinforcing the need for vigilance against UV exposure year-round in this sun-drenched region.

In North-West Botswana, daylight duration follows a predictable yet captivating seasonal pattern, beginning with the longest days in January, when daylight lasts approximately 13 hours. As the year progresses into February and March, the duration remains relatively consistent at 12 hours, providing ample light for both agricultural and daily activities. This extended exposure to sunlight supports the region's natural ecosystems and influences the local lifestyle, promoting outdoor engagement during the warmer months.
As the year transitions into winter with June, daylight dwindles to a minimum of 10 hours, which is brief compared to the earlier months. This reduction persists through July before gradually increasing again, as daylight returns to 11 hours in August, September, and October. Notably, November and December see daylight extend back to 13 hours, heralding the onset of summer once again. This cyclical nature of daylight duration not only affects the wildlife behavior in the region but also impacts farming schedules and outdoor events, aligning the rhythms of life with the changing seasons.
Maun, Botswana experiences a tropical climate characterized by hot summers and mild winters. January and February are the wettest months, with temperatures reaching up to 40°C (104°F) and substantial rainfall of 168 mm (6.6 in) and 194 mm (7.6 in) respectively. The dry season from May to August sees minimal precipitation, with July recording only 1 mm (0.1 in) of rain and temperatures ranging from 1°C (34°F) to 29°C (85°F). With abundant sunshine, particularly in October and November, Maun boasts over 360 hours of sun during these months, making it a warm and inviting destination year-round.
