October begins with the Ottobrata: sunshine and temperatures up to 29°C.

October 1, 2026, begins with the arrival of the "Ottobrata," a period of fine weather typical of early autumn. High pressure, extending from North Africa and linked to an anticyclonic area between Russia and Eastern Europe, ensures stable and sunny conditions across much of Italy. In central-southern regions and the Northeast, daytime maximum temperatures reach up to 28–29°C, about 4°C above the climatological averages for this period.

The pressure configuration places Italy at the center of a high-pressure corridor, guaranteeing predominantly fine weather for the coming days as well. Only some areas, such as the western Alps and Sardinia, may experience variability with some harmless cloud cover and local drizzle. Temperatures remain at late-summer levels, with highs generally between 24 and 26°C in many areas, and coolness limited to the early morning hours.

Ottobrata is a typical meteorological phase of early autumn, characterized by atmospheric stability, a lack of significant wind, and temperatures above the norm. The term precisely describes these periods of unusually warm, fine weather occurring in October. The current situation originated from the expansion of a high-pressure field from the central-western Mediterranean toward Eastern Europe, with barometric highs reaching up to 1035 hPa over the Baltic Republics and Western Russia.

This anticyclone merged with another high-pressure area rising from North Africa, creating a vast, stable corridor right over Italy. This configuration blocks the entry of Atlantic disturbances, which are diverted toward more northern latitudes. The result is an October start with characteristics more akin to late summer, delaying the establishment of typical autumn weather. The immediate consequences are predominantly sunny and mild days, with temperatures in some locations peaking at 30°C.
