The "subtropical phase" that began on May 24th is now numbered, and we can finally glimpse the epilogue of the scorching Summer of 2026, the hottest in Italy's history.

Lorenzo Tedici, meteorologist and media manager at iLMeteo.it, confirms that, in the next few hours, a strong Atlantic disturbance will push the North African dome away from the northwest, causing temperatures to drop by up to 8 degrees.

Tuesday, September 8th will be the last real heat wave: in the North, temperatures will once again reach 35°C, while in the Center-South, thermometers will reach peaks of 36-37°C. By the weekend, all of Italy will return to normal temperatures with highs of 28-30°C everywhere, a value that just a few weeks ago represented the minimum nighttime temperature in Sardinia , Sicily, and along the Tyrrhenian coasts.

Regarding the forecast for the island, according to Arpas, "Thursday is expected to see worsening conditions with possible precipitation, with more clear spells the following day . Temperatures will drop significantly on both sides of the Atlantic on Thursday and remain stable the following day. Winds will blow from the west on both days, with locally moderate strength. Seas will be rough to very rough in places."

This new atmospheric configuration, however, will bring with it the risk of heavy rainfall: the impact of cool Atlantic air on a region still recording a temperature anomaly of +7°C, combined with Italian seas 4°C warmer than the September average, will provide enormous energy for the development of heavy showers and thunderstorms. Rain will begin as early as Tuesday evening in eastern Liguria, Lombardy, and the Alps. On Wednesday and Thursday, the low pressure system will hit the rest of the North more intensely and widely, extending to the central regions on Friday. In this initial phase, Southern Italy will be mostly spared from the most abundant rainfall, then from the weekend the worsening conditions will also affect the South.<br/> <br/> But after the rain and the drop in temperatures, what will happen? Will the heat return? At the moment, the models indicate that we won't have a temporary respite, but a lasting cooldown: although the projections don't rule out some summer-like peaks in the South until mid-month, we can start putting away the fans. We'll go back to sleeping soundly, turning off the air conditioning and being able to throw open the windows at all hours, rediscovering an atmospheric normality that we've been waiting for uninterruptedly for almost four months.<br/> <br/> </p> <p>CTR</p>
