A formidable heatwave, born of an African anticyclone, is tightening its grip on western and central Europe, bringing the second bout of extreme temperatures in less than a month. French forecasters warn that the mercury could locally reach 38 to 40°C in the south-west, with widespread highs above 35°C across many regions from Wednesday. Italy, too, is bracing for a furnace-like weekend, with the Po Valley and inland areas expected to swelter under peaks of 38-39°C and oppressive humidity making nights particularly gruelling. The rapid succession of heat episodes, barely weeks after a punishing May scorcher, underscores a pattern of intensifying early-summer extremes that is taxing public health systems and energy grids.

Germany finds itself squarely in the path of the advancing hot air mass. The national weather service has issued heat warnings for the south and central states, where temperatures are forecast to climb to 32-35°C by Friday, with isolated spots in Saxony, Saxony-Anhalt and Thuringia possibly hitting 38°C. Tropical nights, in which the temperature fails to drop below 20°C, are expected to compound the stress on urban populations. Forecasters caution that the heat will also prime the atmosphere for violent thunderstorms, a volatile cocktail that could bring localised flooding and disrupt transport networks just as the weekend begins.

As the warm front pushes northeast, it is delivering a timely meteorological gift to Scandinavia. After a cool, rain-soaked start to the summer holidays, Swedish meteorologists say the country is set for a dramatic turnaround. The same heat that has baked France and Germany will arrive in a weakened but still potent form, lifting temperatures to around 30°C in many areas for midsummer celebrations. While a few afternoon showers may drift across Halland and other western counties, the overall picture is one of sunny, stable conditions—a reprieve that forecasters are calling the most important weather weekend of the year for outdoor gatherings.

Viewed from a wider lens, the heat is not confined to Europe. Iranian climate experts note that summer across much of the country is projected to be 0.5 to 2°C above the long-term average, with central provinces and the Zagros mountain fringe feeling the greatest anomaly. The persistence of hot conditions well into September challenges any notion of a shortened summer. Back in Europe, the immediate outlook suggests the heatwave will hold through the weekend before a possible thundery breakdown early next week. For a continent still adapting to the rhythm of recurring heat extremes, the episode is a reminder that high summer is arriving earlier and with greater ferocity.
