Overview

• Météo-France extended its orange heatwave alert to 84 departments for June 30, the widest coverage since the alert system was introduced.
• Forecasts call for daytime highs of 30–34°C in northern regions, 34–38°C in central areas and up to 41°C near the Mediterranean, with overnight lows remaining above 20°C in many locales.
• A powerful anticyclonic “dôme de chaleur” is blocking cooler air and is expected to sustain the heatwave until at least Tuesday, with peak intensity around midweek.
• The government has ordered about 200 public schools to close through midweek, convened an interministerial crisis meeting and reactivated the national heat-health hotline.
• This marks France’s 50th national heatwave since 1947 and follows red alerts in Italy and warnings in Portugal and Spain as Europe records escalating extremes.
