Short summary
Extreme weather conditions can strongly affect arable crop growth and final yields. Early heat waves over Italy from 1995 to 2013 are identified and characterised, and their impact on durum wheat yields is investigated. Results confirm the impact of the 2003 heat waves and highlight a high percentage of concurrence of early heat waves and significant negative yield anomalies in 13 out of 39 durum wheat production areas. In the most important area of production this percentage exceeds 80%.
