Why is it not hot in dog days this year?

Climate change may lead to abnormal weather, including increased rainfall and decreased temperature. The change of atmospheric circulation pattern may lead to the failure of hot air to effectively conduct to the ground, thus reducing the feeling of heat. Other natural factors, such as abnormal sea surface temperature and the activity of meteorological system, may have an impact on the heat in dog days.
