When we have direct sunlight, the temperature is higher compared to indirect sunlight.
Direct sunlight is usually overhead whereas indirect sunlight is at an angle to the surface.
- Direct sunlight impacts the surface with more energy concentrated on a smaller surface area.
- This warms the surface more.
- Indirect sunlight is diffuse and spreads over a wider area.
- This leads to a reduction in temperature.
