Factors Contributing to Phoenix’s High Temperatures
Phoenix’s geographic location and unique weather patterns contribute to its consistently high temperatures, especially during the summer. Several factors contribute to this:
- Desert Environment: Located in the Sonoran Desert, Phoenix experiences intense solar radiation and low humidity.
- Urban Heat Island Effect: Concrete and asphalt absorb and retain heat, raising temperatures in urban areas.
- Monsoon Season: While monsoons bring rain, they also increase humidity, making the heat feel even more oppressive.
- High Pressure Systems: Persistent high-pressure systems during the summer months create stable atmospheric conditions, leading to prolonged periods of sunshine and heat.
