  • Heat waves commonly occur during the summer when weather patterns are slower to shift.
  • Most often heat waves happen when a ridge of high pressure sits over an area for an extended period of time.
  • Dry air moves down, compresses and warms, quickly heating the ground.
  • This raises the air temperature, and since high pressures are typically cloud free, the increased sunlight also contributes to the warming air.
