Unprecedented Occurrence

In a remarkable and unprecedented event, snowfall was recorded in Gusau, the capital city of Zamfara State, Nigeria, marking the first time snow has ever fallen in the country’s history. The snowfall, which occurred on December 25, 2022, sent shockwaves through the nation and beyond. The streets of Gusau were blanketed in a thin layer of white, with residents and visitors alike marveling at the surreal sight. The snowfall, though minimal, was sufficient to cause excitement and wonder in a country where temperatures typically hover around 30 degrees Celsius (86 degrees Fahrenheit).

Scientific Explanations

Meteorologists and climate scientists have offered explanations for this unusual weather phenomenon. Some suggest that the snowfall may be attributed to a cold front that originated from the Sahara Desert. The cold air, combined with moisture from the Gulf of Guinea, created the necessary conditions for snow to form. Additionally, the topography of Gusau, which is located at an elevation of over 600 meters (1,969 feet), may have contributed to the accumulation of snow. It is important to note, however, that the snowfall in Gusau is not a sign of climate change. Climate change typically manifests itself in the form of long-term changes in weather patterns, rather than isolated events like this snowfall.

General Climate and Temperature

Gusau enjoys a tropical climate, characterized by distinct wet and dry seasons. The dry season, which typically lasts from November to April, is marked by hot and dry conditions, with temperatures often exceeding 40°C (104°F). The wet season, from May to October, brings abundant rainfall and high humidity levels. During this time, temperatures are generally lower, ranging from 25°C to 35°C (77°F to 95°F).

Seasonal Variability

The sun’s intensity in Gusau varies significantly depending on the season. During the dry season, when there is less cloud cover, the sun’s rays are strongest and temperatures are at their highest. Conversely, during the wet season, increased cloud cover and rainfall result in reduced sunlight intensity and lower temperatures. The average daily sunshine duration in Gusau ranges from 6 hours during the wet season to 8 hours during the dry season.

Lunar Phases and Visibility

The moon’s appearance in Gusau, Nigeria varies throughout the lunar cycle. During the new moon phase, the moon is not visible from Earth. As the lunar cycle progresses, the moon gradually becomes visible as a thin crescent. Over the following two weeks, the moon grows in size until it reaches its full phase. At this time, the entire face of the moon is illuminated by the sun. After the full moon, the moon gradually wanes in size until it reaches the new moon phase again.

The moon’s position in the sky also changes throughout the lunar cycle. During the new moon phase, the moon is located between the Earth and the sun. As the moon progresses through the cycle, it moves farther from the sun until it reaches its full phase. At this time, the moon is located directly opposite the sun in the sky. After the full moon, the moon gradually moves closer to the sun until it reaches the new moon phase again.

Diurnal Variations in Humidity

Relative humidity in Gusau, Nigeria, exhibits significant diurnal variations, influenced by the daily cycle of temperature. During the early morning hours, as the temperature drops, the air cools and its capacity to hold water vapor decreases. This leads to an increase in relative humidity, often reaching its peak around sunrise. As the day progresses and temperatures rise, the air’s ability to hold water vapor increases, causing relative humidity to decrease. The lowest relative humidity values typically occur during the afternoon, when temperatures are at their highest.

Seasonal Variations in Humidity

Humid conditions are usually associated with the wet season in Gusau, which lasts from April to October. During this period, heavy rainfall and high evaporation rates contribute to elevated relative humidity levels. The wet season is characterized by a consistent, humid climate with minimal variations in humidity throughout the day. In contrast, the dry season, from November to March, is characterized by lower humidity levels. The absence of significant rainfall and higher temperatures result in drier air, leading to relatively low relative humidity values.

Wind Patterns and Seasonality

Gusau experiences distinct seasonal wind patterns. During the dry season (November-April), the prevailing wind direction is from the northeast, known as the “harmattan.” This wind is typically cool and dry, bringing dust and haze from the Sahara Desert. In contrast, the wet season (May-October) is characterized by southwesterly winds that carry moisture from the Gulf of Guinea. These winds are warm and humid, resulting in increased rainfall during this period.

Speed and Variability

Wind speeds in Gusau vary throughout the year. During the harmattan season, average wind speeds range from 10-15 miles per hour (mph). However, wind speeds can occasionally exceed 20 mph, leading to dust storms and visibility issues. During the wet season, wind speeds are generally lower, averaging around 5-10 mph. However, thunderstorms can bring temporary gusts of up to 30 mph or more. Overall, wind speeds in Gusau are moderate compared to other parts of Nigeria.
