Hot here means 34.9 °C or above, a level about one summer day in twenty used to reach at this station between 1971 and 2000. The bar has not moved; the number of days clearing it has. Every year counted over the whole window; this season is complete, so no year is cut short. That threshold is Rome's own. It is not a national standard and it is not comparable with another city's: every figure on this page is measured against this station and nothing else.
76 nights that never dropped below 20 °C, against 7.9 in a typical 1961-1990 summer. That is 1st of its 73 summers.
Rome's hottest day this year, 39.6 °C, is 6th on this record. The previous best is 40.6 °C in 1981, the dot on the drop line. A typical summer here peaks at 36.8 °C. Its hot-day count is the most on record in its 2026 summer: a count and a peak are different claims, and neither borrows the other's rank.
