National Thermal Indicator
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 7 March 2026
Over the coming days, the national thermal indicator is expected to gradually return to values between +6 and +3.
Under these conditions, daytime temperatures may still reach 13 to 20°C on the mildest days, although they will most often range between 10 and 17°C.
From 14 March onward, the trend would indicate a renewed decline in the national indicator, which could fall between +3 and –1.
Maximum temperatures would then range between 8 and 15°C on the milder days, while cooler periods would limit highs to around 7 to 13°C.

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
UPDATE – 6 March 2026
A 1029 hPa high-pressure cell will reach the North Sea on Saturday, temporarily directing more humid maritime air toward the north-western part of the country.
On Sunday, this high will merge with the main anticyclone of 1034 hPa, centred over Belarus.
This pattern will maintain a still very mild continental flow across the country until early next week. From Tuesday onward, however, conditions will become more unstable with the passage of a weak cold front approaching from the west.
By mid-week, the south to south-westerly flow ahead of a new disturbance will strengthen. The incoming air, originating from western France and the Bay of Biscay, will gradually become less mild.
Further rain-bearing frontal systems are expected to cross the region toward the end of the week and during the following weekend, within an increasingly cooler maritime air mass.

Trend of 500 hPa anomalies (around 5500m) across Europe and the Atlantic Ocean
Maps
Update – 5 March 2026
Trend for late March and early April
Medium-tropospheric guidance indicates a persistent high-pressure regime over northern Europe and the north-eastern Atlantic, while low-pressure systems are expected to remain focused mainly over the southern Mediterranean Basin and the Maghreb.
For our regions, this pattern implies a sustained influx of dry continental air. Temperatures are likely to remain generally above seasonal averages, with predominantly calm conditions and limited significant precipitation.

Weather Outlook for 3-4 weeks
Update – 6 March 2026
Week of 23–29 March: dry weather and possibly cooler conditions
The currently favoured scenario in the models maintains a dominant high-pressure system over northern Europe. Under such a pattern, disturbances would remain scarce across our regions and the general atmospheric flow would stay rather weak.
This setup would favour mostly dry conditions. It could also lead to marked daily temperature ranges, with rather cool mornings under often clear skies followed by mild and distinctly spring-like afternoons.
Week of 30 March to 5 April: a last potentially damaging frost for crops?
During this transitional week between late March and early April — approaching the Easter period — weather conditions should remain generally calm and rather dry.
However, an intrusion of cooler air from the north cannot be ruled out. In such a scenario, attention will need to be paid to the risk of spring frost. Following a very mild end to winter and advanced vegetation growth, a return of frost could locally cause significant damage to crops.
At this stage, the reliability of this outlook remains limited and will require confirmation in the coming days.
***************
Weather Outlook for 3 months
Update 11-2-26
March: slightly drier, more often under high pressure influence
Temperatures:
The most likely scenario points to values near or slightly above the seasonal average. The projected anomaly is around +0.7°C, with fairly good confidence. Short-lived cooler spells remain possible.
Precipitation:
No clear nationwide signal. Alternating unsettled and quieter phases may produce marked regional contrasts. The expected anomaly is around -5%, but with low confidence.
General pattern:
The circulation remains fairly mobile, with a low-pressure axis still extending from the Atlantic towards Spain, gradually weakening. This may evolve into a typical late-winter/early-spring regime, with rapid shifts between mild westerly/southwesterly flows and cooler incursions.
April: broadly seasonal
Temperatures:
Close to average or slightly above, depending on the region. The anomaly is estimated at +0.6°C, with fairly good confidence — a moderate deviation close to normal. Cold, occasionally frosty nights remain possible during calm high-pressure periods.
Precipitation:
A slightly drier tendency during anticyclonic phases (-7%), though confidence is limited.
General pattern:
The Benelux is often positioned between low-pressure systems over southern Europe and the Mediterranean and more persistent high pressure over eastern Europe.
May: variable, without significant anomaly
Temperatures:
Near-average values, around +0.5°C (not statistically significant). Under clear skies and northerly high-pressure flow, cool or locally frosty nights remain possible, despite generally mild daytime conditions. Confidence is limited.
Precipitation:
A slightly drier signal (around -10%), but with very large scenario spread. Typical spring showers, sometimes thundery, cannot be ruled out.
General pattern:
The Atlantic high may at times promote northerly flows, favouring cooler nights and reduced precipitation.
