National Thermal Indicator
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 8 March 2026
Over the next two days, the national thermal indicator is expected to remain between +5 and +6.
Under these conditions, daytime maximum temperatures could still reach 13 to 20°C across many parts of the country.
From Tuesday 12 March, however, the trend points to a slight decrease in the thermal indicator, which may settle between +2 and +5.
Maximum temperatures would then range between 9 and 16°C.
From 14 March onward, the index, continuing its decline, should fluctuate around neutrality (+1/-1), corresponding to temperatures closer to seasonal averages, generally between 6 and 14°C depending on the day and the region.

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
UPDATE – 8 March 2026
Very mild air will still flow across our regions on Monday, but the atmosphere will gradually become more unstable with an increasing risk of local showers.
On Tuesday and Wednesday, an unstable flow will establish itself from western France and the Bay of Biscay. The air will become slightly less mild ahead of a moderately active cold front bringing rain.
On Thursday, this disturbance will be followed by a temporary lull in the weather. However, this improvement will be short-lived, as another fairly active rain band is expected to cross our regions on Friday.
During the weekend and at the beginning of next week, weather conditions are expected to remain unsettled. At times it will turn rather cool, with showers or wintry showers in an oceanic flow gradually veering to the west and later to the northwest.

Trend of 500 hPa anomalies (around 5500m) across Europe and the Atlantic Ocean
ALL Maps
Update – 7 March 2026
Outlook for late March
Projections at the mid-tropospheric level indicate the development of a broad anticyclonic area extending from northern Scandinavia towards the Atlantic Ocean, while a low-pressure system would remain established over the Mediterranean Basin.
In this pattern, our regions would experience a continental airflow bringing relatively mild and fairly dry air, favouring generally stable conditions with limited precipitation.
Early April
At the beginning of April, the anticyclonic area is expected to shift further west towards Iceland, while the Mediterranean low would remain centred near Tunisia.
Such a configuration would generate a northerly to north-easterly flow over our regions. The air mass would remain rather dry, although temperatures would tend to return to values closer to the seasonal average.

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.
