Editing Ancona (section)

=== Climate ===
The climate of Ancona is [[humid subtropical]] (Cfa in the [[Köppen climate classification]]) and the city lies on the border between mediterranean and more continental regions. Precipitations are regular throughout the year. Winters are cool (January mean temp. {{convert|5|°C|0|disp=or|abbr=on}}), with frequent rain and fog. Temperatures can reach {{convert|-10|°C|0|abbr=on}} or even lower values outside the city centre during the most intense cold waves. Snow is not unusual with air masses coming from Northern Europe or from the Balkans and Russia,{{citation needed|date=September 2024}} and can be heavy at times (also due to the "[[Lake-effect snow|Adriatic Sea effect]]"), especially in the hills surrounding the city centre. Summers are usually warm and humid (July mean temp. {{convert|22.5|C|F|1|disp=or|abbr=on}}). Highs sometimes can reach values around {{convert|35|and|40|C|F}}, especially if the wind is blowing from the south or from the west ([[föhn wind|föhn effect]] off the [[Apennine Mountains]]). Thunderstorms are quite common, particularly in August and September, and can be intense with occasional flash floods, damaging winds and even large hail. Spring and autumn are both seasons with changeable weather, but generally mild. Extremes in temperature have been {{convert|-15.4|C|1}} (in 1967) and {{convert|40.8|C|1}} (in 1968) / {{convert|40.5|C|1}} (in 1983).
