From 2000 to 2020, data from 49 weather stations were used, which also incorporated a unique 69-year series of soil temperature measurements from the Doksany station, where measurements have been obtained since 1952. First, climatological statistics for the observed soil temperatures at various depths and time scales were calculated. Second, a comprehensive analysis of soil temperature trends and their links with atmospheric variables was performed. Third, daily soil temperature anomalies (DSTs) at various depths were calculated through the use of standardized values (z‐DST scores). To demonstrate that precipitation triggered a drop in DSTs, we also applied a quantile-based analysis to rainfall-DST-coupled datasets. Compound air–soil heat events in the warm half-years were quantified. Finally, three critical soil temperature thresholds were established, and three minimum soil temperature, namely, lower than − 3 °C, − 5 °C, and − 7 °C were designated as being critical for wheat plants with low, moderate, and high frost tolerance, respectively. We found that the effects from soil warming at all depths and seasons have increased and that the risk of critical winter soil temperatures that cause stress-induced damage in wheat surprisingly increased over the study period. The risk of winterkill is between 28 and 39% in most wheat-planting areas. The most frequent intense long-lasting heat waves occurred in the postheading stage of winter wheat.
