The heat wave is once again looming over Paris and the Île-de-France as July 2026 gets underway. Just a week ago, the capital was gasping for air: ten straight days above the symbolic 35°C mark, with two record highs of 40.6°C on June 24 and 40.1°C on June 25. Since then, the mercury has eased to a far more tolerable level, so much so that it barely reached 25°C this Wednesday. But this respite looks short-lived, according to the latest projections shared by Meteored.
A fresh heat wave is headed for the south of France in the coming days, with a very likely return of scorching conditions in several departments. The question on everyone's lips now: will the Île-de-France region manage to dodge it?
Under the influence of a high-pressure system, sun and heat are settling in for good across the country, at least until the end of next week, with not a drop of meaningful rain in sight (a development that could seriously worsen the drought in the meantime). In Paris, temperatures are rising gradually, and Thursday looks set to be the coolest day of the next ten. So make the most of it.
Here are the temperatures expected for Paris, according to projections from the European ECMWF model:
All weather models are flashing red, but not in the same way. Where the European model foresees heat that grows but remains contained, the American GFS is markedly more alarming: it projects from the start of next week temperatures around 34 to 35°C in Île-de-France, and its most pessimistic scenario even points to peaks near 38°C midweek.
On its side, Météo-France confirms the trend: France will probably face a new heatwave starting this weekend, though the duration and intensity remain to be determined. You can read more about what to expect in our piece on the return of the heat to Île-de-France this weekend. A new orange heatwave alert, or perhaps red, cannot be ruled out in the coming days.
As we await more details, here’s a quick guide to beating the heat: our ideas for refreshing outings in Paris when it’s scorching, plus a roundup of swimming spots in Paris and Île-de-France this summer 2026, along the Seine and the Marne.
