Precipitation in the Northern Red Sea region of Eritrea follows a pronounced seasonal trend, concentrated primarily in the cooler months. January and December are the wettest months, receiving 74 mm (2.9 in) and 76 mm (3.0 in) of rainfall, respectively, characterized by 14 and 14 rainy days. February also contributes significantly with 71 mm (2.8 in) spread over 15 days. As the year progresses into spring, precipitation sharply declines, dropping to only 28 mm (1.1 in) in March and further reducing to 16 mm (0.6 in) in April, and a minimal 14 mm (0.5 in) in May, each associated with fewer rainy days.
The summer months witness a stark decrease in rainfall, with June receiving just 1 mm (0.0 in) and July and August each accumulating 7 mm (0.3 in) and 8 mm (0.3 in). By September, rain becomes almost negligible with only 1 mm (0.1 in) recorded. The autumn months see a slight resurgence in precipitation, peaking again in November at 47 mm (1.9 in). Overall, the region experiences a clear seasonal drought during the summer, contrasting with the wetter, more variable conditions typical of the winter months, emphasizing its arid desert climate.
Sunshine duration in the Northern Red Sea region of Eritrea exhibits a notable seasonal progression, marked by an increase from winter to summer months. Beginning with a solid 255 hours in January, the region experiences a steady rise, reaching 278 hours in February. This upward trend continues through the spring, hitting 339 hours in March and peaking at 351 hours in May, which represents the sunniest month of the year. As summer progresses, sunshine remains abundant, fluctuating between 342 hours in July and 335 hours in August, underscoring the region's characteristic bright and arid climate.
As the year transitions into the autumn months, sunshine hours begin to taper off, with September recording 325 hours—still considerable but a drop from the summer peak. October sees a slight increase to 329 hours, while November and December further decrease to 313 hours and 315 hours, respectively. Overall, this annual cycle highlights not only the abundance of sunlight during the hotter months, crucial for solar energy potential and agricultural practices, but also the gradual decline toward winter, suggesting a pronounced shift in climatic conditions as the year progresses.
The UV Index in the Northern Red Sea region of Eritrea reflects a pronounced intensity throughout the year, with values predominantly falling into the very high and extreme exposure categories. Beginning in January, the UV Index registers at 9, categorized as very high, requiring just 15 minutes of sun exposure for potential skin burn. This trend intensifies in February, reaching 10, and peaks in March and April, where it hits 12—indicating extreme levels of UV radiation and a notably reduced burn time of only 10 minutes. May still reflects high UV intensity at 11, reinforcing the notion that spring ushers in some of the highest sun exposure risks.
As the summer months unfold, the UV Index slightly decreases but remains high, recorded at 10 in both June and July, with consistent burn times of 15 minutes across these months. August continues this pattern, maintaining a UV Index of 10 before returning to 9 in October and November, while December sees a mild reduction to 8. Overall, this data emphasizes the importance of sun protection measures year-round, particularly during the spring, when extreme UV levels pose significant risks for skin damage and necessitate swift preventive actions for those engaging in outdoor activities.
