4. Rainfall
Rainfall is an important component of Charleston, South Carolina's average temperature. The amount of rainfall a city receives can affect its temperature in several ways.
1. Evaporation: When rain evaporates, it takes heat from the surrounding environment. This can help to cool down the air and lower the temperature.
2. Cloud cover: Clouds can block sunlight, which can help to keep the air cooler. Rainfall can increase cloud cover, which can help to lower the temperature.
3. Soil moisture: Wet soil can release heat more slowly than dry soil. This is because water has a higher specific heat capacity than soil. As a result, cities with more rainfall tend to have cooler temperatures than cities with less rainfall.
4. Latent heat release: When rain condenses, it releases latent heat. This heat can help to warm the air and raise the temperature.
The relationship between rainfall and temperature is complex and can vary depending on the specific climate. However, in general, cities with more rainfall tend to have cooler temperatures than cities with less rainfall.
The average rainfall in Charleston is 45 inches per year. This is higher than the national average of 38 inches per year. The high rainfall in Charleston helps to keep the city's temperature relatively cool, even during the summer months.
Here are some examples of how rainfall can affect temperature in Charleston:

- During the winter months, rainfall can help to keep the ground warm and prevent the temperature from dropping too low.
Overall, rainfall is an important factor in determining Charleston's average temperature. The high rainfall in Charleston helps to keep the city's temperature relatively cool and comfortable year-round.
5. Hurricanes
The location of Charleston on the Atlantic coast makes it prone to hurricanes, which can have a significant impact on the city's average temperature. Hurricanes are large, rotating storms that form over warm ocean waters. They can bring high winds, heavy rain, and flooding to coastal areas. When a hurricane makes landfall, it can cause widespread damage and power outages. The average temperature in Charleston can be affected by hurricanes in several ways:
- Wind: The high winds associated with hurricanes can cause trees and power lines to fall, which can lead to power outages. Power outages can disrupt air conditioning and heating systems, which can make it difficult to maintain a comfortable temperature inside homes and businesses.
