Hot here means 33.7 °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 Mar del Plata'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.
4 nights that never dropped below 20 °C. No multiple is quoted here. Mar del Plata averages about 3.1 a year, and dividing by a base that thin produces a large number and no evidence. 28 of the 54 cities are gated this way.
Mar del Plata's hottest day this year, 38.7 °C, is 7th on this record. The previous best is 42.4 °C in 2021, the dot on the drop line. A typical summer here peaks at 35.8 °C. Its hot-day count is 15th of 70: a count and a peak are different claims, and neither borrows the other's rank.
