General Weather Evolution for the Next 6 Days

Europe: Analysis & Forecast maps (6 days)

Update – 21 July 2025 at 120 AM – Evolution of the Weather Pattern

Atmospheric evolution

A fresh and unstable oceanic airflow from the west to southwest is currently shaping our weather, resulting in a mix of bright spells and occasional, sometimes intense, showers.

From Wednesday onwards, this rather humid flow will veer more towards the west or northwest, remaining unstable — particularly inland — but gradually bringing milder conditions by Friday and Saturday.

Over the weekend, a ridge of high pressure may develop over the British Isles, leading to a more stable atmosphere. However, a weak disturbance could still brush past on Sunday, bringing the risk of a few scattered showers.

Weather Outlook for Summer 2025: a very warm, often stormy quarter

Following a historically warm June (around +3°C above average), the summer is expected to continue under generally warmer-than-normal conditions, with a seasonal temperature anomaly of +1 to +2°C. Here’s what to expect by month:

July 2025: the hottest month of the summer
Temperatures are forecast to be well above average, with anomalies of +2 to +2.5°C, according to most models.
It is likely to be the hottest month of the summer, with frequent heat spikes and potential heatwaves.
Storm activity may be less pronounced than in June, with strong regional disparities.
Models such as ECMWF and the UK Met Office point to a significant rainfall deficit, worsening the impacts of heat.

August 2025: still warm, but stormier
The heat will persist, with a thermal surplus of +1 to +1.5°C.
A shift toward a more oceanic flow may increase instability, leading to more frequent thunderstorms and rain showers.
Storms are expected to become more common.
The month will remain warm, though somewhat less extreme than July.

September 2025: increased instability
Temperatures should remain above seasonal norms, but more moderately (+0.5 to +1°C).
Weather patterns may become more unsettled, with a return to Atlantic-driven circulation and more regular rainfall.
Wetter episodes are likely.
This setup may mark a transition toward a more active start to the meteorological autumn.
