After an extraordinary September, should we bring out the lighter clothing again? France emerges from a weather pattern marked by exceptional heat and troubling drought. And now a new shift appears, with sun and milder air returning as early as next week. Between record values and forecasts for the next two weeks, here is what this change could mean for your region.
- A warming trend takes hold from October 12, with nights not dropping below 8 °C in major cities
- Aquitaine could reach 25 to 28 °C on Tuesday October 13, while the north and areas near the Channel stay cooler and under the influence of weakened disturbances
- This warmth does not solve the water deficit, with soil dryness and groundwater reserves remaining at concerning levels according to BRGM
- A warm spell is forecast across France starting Monday, October 12
- Aquitaine could flirt with 25 to 28 °C on Tuesday the 13th
- Will the North and areas near the Channel escape the disturbances?
A Warm Spell Is Forecast Across France Beginning Monday, October 12
The weather is taking on a new look. In its October 7 forecast issued at 7:04 a.m., Meteored forecaster Alexandre Slowik anticipates a warming from Monday the 12th, intensifying on Tuesday the 13th, with a return of high pressure and milder air. The Azores anticyclone should push a ridge toward France, then settle over the entire week, spanning from the Azores to Italy via our country. This classic weather pattern, unusually pronounced this time, confirms a trend already observed: nights should not fall below 8 °C in major cities by October 13. It is a clear signal that fits with a September that was already off the charts, since Météo-France ranked it as the second warmest September on record since 1900, with an anomaly of +3.1 °C. Only September 2023 was warmer, at +3.6 °C. This marks the fourth consecutive month with an anomaly above +3 °C, a stretch not seen for so long in the data.
Aquitaine Could Approach 25 to 28 °C on Tuesday the 13th
The warmth is expected to be felt most in the southwest. Some models project values between 25 and 28 °C in Aquitaine, with a peak anticipated on Tuesday, October 13. The region remains the most exposed to high temperatures for October, continuing a summer that stretched far beyond the usual calendar. Remember that on September 6, Lavaur, in Tarn, set a national September record with 40.3 °C on the thermometer. While such extreme levels aren’t anticipated this week, the forecasted warmth reinforces a broader trend: the southwest remains particularly vulnerable to late-season heat events. For locals, a few simple precautions are wise: air out homes early in the morning, limit vigorous activity to the cooler parts of the day, and monitor hydration, especially for the elderly or more fragile individuals. This context adds to a drought of soils already described as unprecedented for this part of the year, with a southwest/north-east axis especially affected.
Will the North and Areas Near the Channel Escape the Disturbances?
Not all regions will experience this warm spell in the same way. If the southwest looks set to be the most exposed to higher values, the northern scenario remains different. Elsewhere in the country, the outlook is more for mildness than summertime heat, according to Slowik’s analysis. Regions near the Channel and Belgium could stay under the influence of weakened disturbances, which will nuance the overall sunny picture. Nothing alarming, but enough to keep a rain umbrella handy if you live in those areas. Based on the 15-day forecasts released by Météo-France on September 29, temperatures are expected to stay near seasonal norms through October 25, with no cold snap announced at this stage. A mild autumn is on the horizon, but it’s important not to forget the drought: BRGM noted in early October that groundwater conditions have changed little, meaning this warm spell will not resolve the accumulated hydrological deficit since summer.
This return of milder weather offers welcome relief before the chill of winter, but it should not obscure the broader context: soil dryness, groundwater under strain, and a climate that continues to set records. Enjoy the gentler days, but keep an eye on water consumption and on the usual safety guidance, especially if you live in the southwest. The week looks pleasant, yet it does not erase the long-term climatic challenges that are taking hold.
