A significant heatwave is expected to sweep across Europe this week, with temperatures soaring into the mid-30s Celsius in many regions. A mass of hot air originating from the Sahara has settled over the Iberian Peninsula and is spreading into southern and western France, pushing temperatures widely into the low to mid-30s.
Heat Spreads North and East
By midweek, this hot air mass is forecast to extend northeastward across the continent. On Friday, maximum temperatures are predicted to reach the mid-30s in several countries, including Germany, Italy, and Czechia. Depending on the location, these readings are expected to be 9–13°C above the 1991–2020 climate average.
The United Kingdom is not expected to be completely spared. Forecast models indicate that occasional plumes of warm air could move north from the continent on Thursday and Friday, potentially pushing temperatures into the mid- to high-20s across southern and eastern England.
Heatwave Conditions and Duration
In some areas, up to five consecutive days of mid-30s temperatures could meet the official definition of a heatwave. However, the heat is expected to ease for most regions by early next week.
Australia Experiences Mild Winter Start
Europe is not alone in experiencing above-average temperatures. Parts of Australia are likely to continue their mild start to winter. A slow-moving low-pressure system south of South Australia is drawing warm northerly air across the eastern half of the country, while also bringing gusty conditions.
In Melbourne, temperatures are forecast to reach the high teens Celsius on Tuesday and Wednesday, about 3–4°C above average. Overnight temperatures are expected to show a similar departure, nearing the mid-teens—typically 5–6°C above average.
Recurring Pattern Linked to El Niño
While these conditions are not considered extreme, they are expected to remain a recurring feature of the Australian winter. The national Bureau of Meteorology has linked the pattern to developing El Niño conditions in the Pacific Ocean, which typically bring warmer than average daytime temperatures to much of the country.
