In winter, particularly in January and February, temperatures can drop to a minimum of -4°C (25°F), with average highs reaching around 25°C (77°F), signaling a cool and temperate season. As spring approaches, temperatures rise significantly, peaking in April with averages of 21°C (69°F) and maximums of 39°C (102°F). The summer months of June and July experience extreme heat, with average daily temperatures soaring to 34°C (93°F) and maximums hitting a blistering 47°C (117°F). Autumn brings relief, as temperatures gradually decline, with milder conditions in October and November. This seasonal cycle underscores the region's dynamic and harsh climate, impacting both the environment and human activity throughout the year.
Turaif experiences a temperature range from a minimum of -4°C (25°F) in January to a maximum of 45°C (113°F) in July, as detailed in the monthly temperatures in Turaif. Similarly, Arar has a minimum temperature of -4°C (25°F) in February, with a slightly higher maximum of 47°C (117°F) in July, as found in the monthly temperatures in Arar.
Precipitation in the Northern Borders Region of Saudi Arabia follows a distinct seasonal pattern, primarily concentrated in the cooler months of the year. January and February are the wettest months, receiving 10 mm (0.4 in) and 20 mm (0.8 in) of rainfall, respectively. This early winter precipitation contributes to the region's overall moisture, although it is sparse throughout the year. The spring months, particularly March and April, see further slight rainfall (12 mm and 10 mm, respectively), but as temperatures rise in May, precipitation drops dramatically to only 3 mm (0.1 in).
The summer months of June through September experience a notable drought, with no recorded precipitation during this time, reflecting the region's arid climate. As the season transitions into fall, minimal rain reappears in October and November, bringing 3 mm (0.1 in) and 15 mm (0.6 in) of rainfall, with December contributing 13 mm (0.5 in). This irregular precipitation pattern, characterized by brief rainy periods and extensive dry spells, significantly influences the local ecosystem and agricultural practices.
The Northern Borders Region of Saudi Arabia experiences a significant increase in sunshine duration from winter to summer, reflecting the region's arid climate. Beginning in January with 234 hours of sunshine, the days gradually lengthen as spring approaches, culminating in a peak in sunshine hours during the summer months. Notably, June and July stand out with 386 hours and 397 hours of sunlight, respectively, providing nearly 13 hours of daylight each day. This abundance of sunshine during the summer not only influences the region's temperature but also impacts local agriculture by maximizing photosynthesis during the growing season.
As the summer wanes into autumn, sunshine hours remain substantial but begin to decline, with September still boasting 341 hours. This gradual reduction continues into the late fall and winter months, with November and December recording 284 hours and 285 hours of sunlight. Despite the decrease, these figures still indicate a relatively sunny environment compared to many other regions. Overall, the sunshine duration in the Northern Borders Region illustrates a clear seasonal trend, marked by longer, sun-filled days in the warmer months and a shift towards shorter days as the year progresses.
The UV Index in the Northern Borders Region of Saudi Arabia exhibits a pronounced seasonal variation, reflecting the intense solar radiation typical of desert environments. Beginning in January with a UV Index of 5, categorized as moderate, the risk of harm from unprotected sun exposure is relatively low. However, as winter transitions into spring, the UV Index escalates sharply, reaching a notable 9 in March and peaking at 10 in April, both classified as very high. These months signal a critical need for sun protection, with recommended burn times dropping to just 15 minutes.
The summer months bring the highest UV Index readings, soaring to an extreme 13 in May and June, followed closely by 12 and 11 in July and August, respectively. During this period, the burn time significantly decreases to 10 minutes, highlighting an urgent need for protective measures against sun exposure. As the year progresses into autumn, the UV Index gradually diminishes, settling back to a high level of 6 in November and returning to a moderate 5 in December. This trend underscores the importance of understanding seasonal changes in UV exposure, particularly for residents and visitors in this arid region.
