Precipitation in Western Ghana exhibits a pronounced seasonal pattern, aligning with the region's tropical monsoon climate. The year begins relatively dry with 38 mm (1.5 in) of rainfall in January, but moisture levels steadily increase from February to March, culminating in significant rainfall of 136 mm (5.4 in) in March as the region transitions toward the rainy season. April follows closely with 137 mm (5.4 in), paving the way for the peak of the rainy season in May and June, where precipitation dramatically rises to 229 mm (9.0 in) and 290 mm (11.4 in), respectively. These months signify a critical period for agricultural activities and natural ecosystems, fostering lush vegetation and biodiversity.
As the rainy season progresses, the precipitation begins to taper off. July experiences a decrease to 184 mm (7.2 in), heralding a gradual decline in rainfall through August with 92 mm (3.6 in), before spiking again in September at 198 mm (7.8 in) and peaking in October with 206 mm (8.1 in). The transition into the dry season becomes evident in November, where precipitation falls to 146 mm (5.7 in), and further reduces to 69 mm (2.7 in) in December. Notably, rainfall distribution is accompanied by varying number of rainy days; for instance, May sees the highest number of rainy days at 27, emphasizing the intensity of the wet season, while the dry months like January and December average around 10 to 17 days, indicating a shift towards more arid conditions. This intricate interplay of precipitation and rainy days underscores the climatic dynamics central to the region's ecological and economic frameworks.
In Western Ghana, sunshine duration follows an intriguing seasonal pattern, showcasing a steady increase during the earlier months of the year. Beginning in January, the region receives 247 hours of sunlight, which gradually rises through February to 273 hours. March and April mark the highlight of this upward trend, with sunshine peaking at 290 hours in March and 291 hours in April. As the rainy season approaches, there is a slight decrease in sunlight hours, dropping to 282 hours in May and continuing down to 238 hours in June. This reduction coincides with the onset of the rainy season, during which cloud cover increases, impacting overall sunshine availability.
However, as the rains begin to diminish, sunshine duration rebounds through the second half of the year. July experiences a resurgence with 275 hours of sunlight, leading into relatively sunny August at 281 hours. September and October maintain respectable totals, with 264 hours and 275 hours respectively. The year concludes with a remarkable increase in sunshine, with November reaching 295 hours and December boasting the highest total of 307 hours. This trend illustrates a fascinating shift from significant sunlight during the first half of the year to a slight dip during peak rainy months, followed by a resurgence in the latter half, highlighting the dynamic interplay between seasonal changes and solar exposure in this tropical region.
In Western Ghana, the UV Index consistently reaches extreme levels throughout the majority of the year, posing significant risks for skin damage and health. Beginning in January, the UV Index registers at 11, categorized as extreme, where even brief exposure—just 10 minutes—can lead to sunburn. February and March maintain this trend with values of 12, highlighting the continuous intensity of ultraviolet radiation as the region moves toward the peak of the dry season. April peaks at an even more intense 14, further reinforcing the need for protective measures during outdoor activities as the sun's rays grow increasingly potent.
As the rainy season approaches in May and June, the UV Index remains high at 13, continuing to require vigilant sun protection even as cloud cover increases. July and August see a slight dip to 12, yet still fall within the extreme exposure category with the same burn time of 10 minutes. September rises back to 13, and October returns to 12, sustaining the pattern of heightened UV levels. Transitioning into November and December, the index drops to 10, earning a classification of very high; however, the burn time increases to 15 minutes, suggesting a marginally reduced risk but still necessitating caution for sun exposure. This consistent and elevated UV Index throughout the year underscores the importance of adopting sun safety practices in Western Ghana.

In Western Ghana, daylight duration exhibits a relatively stable pattern throughout the year, influenced by the region's equatorial position. Both January and February experience approximately 11 hours of daylight, providing a consistent foundation as the year begins. As the seasons transition into March, daylight increases slightly to 12 hours, and this duration remains stable through June. The months of April, May, and June benefit from the same amount of daylight, promoting agricultural activities and enhancing outdoor life during this period.
As the year progresses into the latter half, daylight duration remains remarkably consistent, with 12 hours of light persisting from July through September. This stability signifies an ideal climate for various ecosystem activities and agricultural cycles. However, daylight begins to wane in October, reverting back to 11 hours and continuing this reduced duration through November and December. This gradual return to shorter days highlights the subtle changes in light availability while reinforcing the notion of consistency throughout the year, making Western Ghana's daylight duration a vital component of its climate and agricultural calendar.
