Despite the drop in temperatures, they should remain above seasonal norms in early July. Temperatures are then expected to rise further around July 10, when the atmosphere becomes increasingly heavy and stormy.
Week from June 29 to July 5: towards calm and always warm weather
The heat wave is gradually ending due to the weakness of the anticyclone. Instability increases as thunderstorms pass through early in the week and temperatures drop after those thunderstorms pass. However, temperatures will continue to remain above seasonal norms nationally, especially in the Southeast, where the heatwave is expected to continue.

Week from 6 to 12 July: to a new rise in temperature?
Subsequently, temperatures should rise again with widespread warmth returning across the area thanks to southerly flow and the return of sub-Saharan air masses. The return of the anticyclone will provide more stable and drier weather. This increase should be particularly noticeable in the second half of the week, even as this heat becomes increasingly wetter and stormier weather returns, especially in the south.
Week of July 13 to 19: Strong and humid heat?
Reliability becomes more limited, but the dominant scenario is continued warm but very unstable weather. Indeed, a cold drop may enter the Bay of Biscay with the arrival of more ocean air, which opposes the warm air. This could lead to the development of daily thunderstorms, especially along the southwest/northeast axis where they could be numerous and severe.

Week of July 20 to 26: Hot and humid weather will continue.
Reliability is very limited, but the heat wave may well continue and temperatures will remain above seasonal norms. Regardless, the unsettled weather is expected to continue with frequent thunderstorms possible.
This 4-week trend, updated every Thursday around 5:00 pm, is likely to change significantly with each update.
