Cool morning with fog expected

A cool morning with some fog is expected on Saturday, October 31st, as the day begins under an autumnal atmosphere marked by cool conditions. In many regions, temperatures will register only a few degrees above zero at dawn.

Fog and frost in some areas

Fog and low clouds may form locally in valleys and plains before gradually dissipating during the morning. In some inland areas, light white frosts could even be observed before the return of the sun.

Sunny afternoon ahead

The sun is expected to dominate much of the afternoon once any potential fog has dissipated. An anticyclone will favor dry, stable, and bright weather, offering good conditions for outdoor activities or Halloween celebrations planned in the evening.

Weather in Île-de-France

In Île-de-France, the sky should alternate between sun and some cloudy passages. Temperatures will reach approximately 12 °C to 15 °C in the afternoon, values slightly lower than those observed at the beginning of the month.

Autumnal temperatures across regions

Maximum temperatures should generally fluctuate between 12 and 18 °C depending on the regions, with the most temperate temperatures near the Mediterranean and in the Southwest. The feeling can be accentuated by a northeasterly wind sometimes noticeable, especially on the coasts of the English Channel.

Ideal conditions for Halloween

An ideal evening for Halloween. Children and families participating in traditional Halloween trick-or-treat events should benefit from generally dry weather across much of the country. Although temperatures will drop quickly after sunset, precipitation will remain rare and the sky often clear.
