During the summer months, when the days are longer, the moon may rise and set later, while during the winter months, when the days are shorter, the moon may rise and set earlier.

Seasonal Variations in Humidity

Cardiff experiences significant seasonal variations in humidity levels. During winter months (December to February), humidity tends to be higher, with average relative humidity values ranging from 80% to 85%. This is primarily due to increased precipitation and lower temperatures during this time of the year. As spring approaches (March to May), humidity levels gradually decrease, reaching an average of 75%-80%. The summer months (June to August) are typically characterized by lower humidity, with average values between 65% and 70%. This is because warmer temperatures and reduced rainfall contribute to drier air.

Long-Term Trends and Climate Change

In recent years, Cardiff’s average humidity levels have shown a slight upward trend. While the city still experiences seasonal variations, the overall humidity has been increasing gradually over the past decade. This trend is consistent with global observations of increasing humidity levels in many parts of the world. Experts attribute this trend to climate change, which is leading to warmer temperatures and changes in precipitation patterns. The increase in humidity levels can have various implications for local ecosystems, human health, and infrastructure. For instance, higher humidity can promote the growth and proliferation of certain mold and fungus species, potentially affecting air quality and human health. Additionally, increased humidity can impact building materials and structures, potentially leading to damage and increased maintenance costs.
