However, during the night, temperatures can drop significantly, especially during the winter months, when it can reach as low as 10 degrees Celsius (50 degrees Fahrenheit). The humidity levels in Nouadhibou are generally low, with an average of 65% throughout the year. This dryness contributes to the extreme temperature variations between day and night.

Cloud Cover in Nouadhibou

Nouadhibou, situated on the Atlantic coast of Mauritania, experiences a distinctive cloud cover pattern influenced by its coastal location and the prevailing northeast trade winds. During the summer months (June to October), the air is frequently stable and characterized by a high-pressure system. This stability inhibits cloud formation, resulting in clear skies and abundant sunshine. The clear conditions are ideal for outdoor activities and beach-going.

In contrast, the winter months (November to May) bring a shift in cloud cover as the northeast trade winds strengthen and the air becomes more unstable. These conditions promote the formation of low-level clouds, including stratus and stratocumulus. The cloud cover can vary significantly, sometimes leading to overcast skies and intermittent rainfall. The cloud cover during this season can affect visibility and outdoor activities. However, it also brings respite from the intense heat and creates a more comfortable atmosphere.

Seasonal Precipitation Patterns

Nouadhibou, Mauritania, experiences a desert climate with minimal rainfall throughout the year. The annual precipitation averages a mere 12 millimeters (0.5 inches), making it one of the driest cities in the world. The region’s precipitation is heavily influenced by the Sahara Desert, which blocks moisture-carrying clouds from reaching the area.

During the winter months (December through February), Nouadhibou sees slightly higher precipitation than in other seasons. However, these amounts are still very low, typically ranging from 1 to 3 millimeters (0.04 to 0.12 inches) per month. The summer months (June through August) are the driest, with virtually no rainfall recorded.

Annual Rainfall Patterns

Nouadhibou, Mauritania experiences an extremely arid climate, with minimal annual rainfall. The average yearly precipitation is approximately 20 millimeters (0.8 inches), making it one of the driest cities in the world. Rainfall is sparse and sporadic throughout the year, with occasional light showers or thunderstorms during the winter months (November to April).

Rainfall Variability and Influence of Trade Winds

The rainfall patterns in Nouadhibou are strongly influenced by the Northeast Trade Winds. These winds blow from the northeast, bringing dry air from the Sahara Desert. The winds prevent moisture-laden clouds from reaching the city, resulting in the extreme aridity. Furthermore, the cold ocean currents off the coast contribute to the dry conditions, as they suppress cloud formation and precipitation. As a result, Nouadhibou experiences prolonged periods of drought, with little to no rainfall for several consecutive months.

Historical Snowfall Event

Historically, snowfall in Nouadhibou, Mauritania, is an exceptionally rare occurrence due to the city’s location in the subtropics and proximity to the Atlantic Ocean, which moderates temperatures. However, on January 18, 1964, a remarkable winter storm brought a dusting of snow to the city. This event remains the only recorded snowfall in Nouadhibou’s history.

Causes of Snowfall in Nouadhibou

Despite its rarity, the snowfall in Nouadhibou in 1964 can be attributed to a combination of atmospheric conditions. A cold front from the north brought frigid temperatures, while a moisture-laden wind from the Atlantic Ocean provided the necessary precipitation. The convergence of these factors led to the formation of snow clouds that released the historic snowfall over Nouadhibou.

Climatology

Nouadhibou, situated on the Atlantic coast of Mauritania, experiences a hot desert climate characterized by relentless sunshine throughout the year. The sun’s unwavering presence casts a radiant glow upon the city, resulting in long, scorching days with minimal cloud cover. Temperatures soar during the summer months, reaching average highs of 35 degrees Celsius (95 degrees Fahrenheit). However, the coastal location ensures refreshing sea breezes that temper the sweltering conditions, creating a more bearable climate compared to inland areas.

Solar Radiation

The abundance of sunshine in Nouadhibou makes it an ideal location for harnessing solar energy. The city receives an average of 8.5 hours of sunshine per day, providing ample opportunities for solar power generation. The government has been actively promoting the use of renewable energy sources, including solar power, to reduce reliance on fossil fuels and mitigate climate change. Several large-scale solar projects have been implemented in and around Nouadhibou, showcasing the city’s potential as a solar energy hub.

Lunar Appearance and Observation

In the skies of Nouadhibou, Mauritania, the moon presents a captivating spectacle throughout its lunar cycle. During new moons, the lunar orb disappears from visibility, as the sun’s illumination is hidden behind the moon’s far side. As the moon progresses through its phases, its crescent-shaped silhouette gradually emerges, becoming more prominent each night. During full moons, the moon’s entire face is illuminated, casting a brilliant glow upon the city.

Observers in Nouadhibou can witness the moon’s various appearances through naked-eye observation or with the aid of binoculars or telescopes. The city’s location on the Atlantic coast offers clear views of the night sky, allowing for optimal stargazing conditions. Notable lunar events, such as solar and lunar eclipses, can be observed in Nouadhibou with great clarity.

Humidity Patterns in Nouadhibou, Mauritania

Nouadhibou, a port city in northwestern Mauritania, experiences a desert climate characterized by extremely low humidity levels. Throughout the year, the average relative humidity hovers between 20 and 30%, significantly lower than the global average of 65%. This extreme dryness is primarily due to the city’s coastal location on the Atlantic Ocean, as well as its proximity to the Sahara Desert.

The driest months in Nouadhibou are typically from June to October, when humidity levels often drop below 20%. During this period, the lack of moisture in the air can lead to dry skin, chapped lips, and discomfort for residents and visitors alike.

However, even during these months, the city remains considerably drier than most other locations around the world.

Wind Patterns

Nouadhibou, Mauritania experiences consistent wind patterns throughout the year due to its coastal location on the Atlantic Ocean. The prevailing wind direction is from the north-northeast, blowing onshore from the Atlantic. These north-northeast winds are particularly strong during the months of December to March, when the dry and cool Harmattan wind blows from the Sahara Desert. The Harmattan can reach speeds of up to 60 kilometers per hour (37 miles per hour) and can cause hazy conditions and respiratory irritation.

Wind Speed and Variability

The average wind speed in Nouadhibou is moderate, ranging between 15 and 25 kilometers per hour (9 and 16 miles per hour) throughout the year. However, wind speeds can vary significantly from day to day and can reach higher speeds during storms and cyclones. The variability in wind speed and direction is influenced by the interaction between the trade winds and the local topography, which creates complex wind patterns. During the summer months (June to September), the influence of the monsoon winds from the southwest can result in increased humidity and occasional thunderstorms, accompanied by strong gusts of wind.
