Seasonal Distribution

During the autumn and winter months, the region experiences frequent low-pressure systems that bring heavy rainfall. In contrast, the spring and summer months tend to be more stable, with lighter rainfall and longer periods of sunshine.

Another factor contributing to Derry’s high rainfall is its location in a valley between two mountains, the Sperrin Mountains to the south and the Inishowen Hills to the north. These mountains act as a barrier to moisture-carrying winds, forcing them to rise and condense, resulting in precipitation over the region.

Cause and Characteristics of Snowfall

The snowfall in Derry is caused by several factors, including cold temperatures, the presence of moisture in the atmosphere, and the influence of weather systems. Derry’s proximity to the Atlantic Ocean provides it with ample moisture, which is necessary for the formation of clouds and precipitation. When temperatures drop below freezing, the moisture in the air crystallizes into snowflakes. The size and shape of the snowflakes depend on various atmospheric conditions, such as temperature and humidity.

Impact of Snowfall

Snowfall in Derry can have both positive and negative impacts on the city and its residents. On the positive side, snow can attract tourists and create opportunities for winter sports. It can also enhance the beauty of the city’s landscapes and provide a festive atmosphere during the holiday season. However, snowfall can also cause disruptions to daily life, including transportation delays, power outages, and hazardous road conditions.

Moon Phases

As the moon orbits Earth, the angle at which sunlight strikes it changes, resulting in different moon phases. The main phases of the moon include:

  • Waxing Crescent: A thin crescent of the moon becomes visible as it moves away from the sun and the illuminated portion gradually increases.
  • First Quarter: Half of the moon is illuminated and appears as a half-circle.
  • Waxing Gibbous: The illuminated portion of the moon continues to grow, becoming more than half but less than full.
  • Full Moon: The entire face of the moon is illuminated as it is opposite the sun in the sky.
  • Waning Gibbous: The illuminated portion of the moon gradually decreases, becoming more than half but less than full.

Humidity in Derry, United Kingdom

Derry, located in Northern Ireland, United Kingdom, experiences a temperate oceanic climate with relatively high levels of humidity throughout the year.

During the summer months, humidity levels tend to be higher, often reaching 90% or more, particularly during periods of prolonged rainfall. Conversely, winter months typically see lower humidity levels, averaging around 70%, as the air is generally colder and drier.

The high humidity levels in Derry are primarily attributed to its proximity to the Atlantic Ocean and prevailing wind patterns. The moist air from the ocean is carried inland by westerly winds, contributing to the overall humidity of the region. Additionally, the presence of the Sperrin Mountains to the south of Derry acts as a barrier, preventing drier air masses from reaching the city. As a result, Derry experiences a consistently humid climate, which can sometimes lead to feelings of discomfort and stuffiness, especially during the summer months.
