Global weather shifts: El Niño strength and regional temperature extremes
Global weather patterns are undergoing significant shifts. In Australia, Sydney and surrounding areas experienced extreme heat over the weekend, with temperatures in Richmond reaching 35.4 degrees Celsius, followed by a sharp 10-degree drop due to a cool air front.
In Italy, the expansion of the Azores High is bringing stability and temperatures 4 to 5 degrees above seasonal averages to much of the country. However, southern regions, including Calabria and Sicily, face continued instability and potential thunderstorms due to residual low-pressure systems. A broader shift toward cooler, more seasonal temperatures is expected around September 23, coinciding with the autumn equinox.
On a global scale, NOAA reports a greater than 90% probability of a very strong El Niño event occurring between the boreal autumn and winter. There is a 75% chance that the October-December phase will be the most intense recorded since 1950. This phenomenon is expected to impact global temperatures, with estimates suggesting 2027 could see averages approximately 1.7 °C above pre-industrial levels.
