National Thermal Indicator
MULTIMODEL BMCB
(These forecasts are generally updated daily)
Update – 4 March 2026
Over the coming days, the national thermal index is expected to remain mostly between +6 and +7, confirming the persistence of markedly milder-than-average conditions for early March.
In this context, maximum temperatures will reach remarkable levels for the season, frequently ranging between 13 and 21 °C across the country.
From 8 March onwards, a gradual change is set to begin.
The thermal index is then projected to decline towards values between 0 and +4.
This shift will result in more moderate daytime temperatures: initially between 11 and 18 °C at the start of the period, then between 7 and 14 °C by mid-March.
Even so, these values are expected to remain slightly above climatological averages.

General Weather Evolution for the Next Days over the Ocean and Europe
Europe: Analysis & Forecast maps
UPDATE – 4 March 2026
A strong high-pressure system at 1027 hPa, centred on Thursday over northern Poland, will further intensify over the weekend. It will extend from southern Scandinavia to the Black Sea, with a core pressure reaching 1038 hPa.
Our regions will remain under the influence of a dry and very mild south-easterly to easterly airflow advecting Mediterranean air.
Early next week, frontal systems are expected to move across the British Isles and France, producing scattered showers. These disturbances will increasingly affect our weather, within an air mass that remains mild, though less exceptionally so for the season.

Trend of 500 hPa anomalies (around 5500m) across Europe and the Atlantic Ocean
Maps
Update – 2 March 2026
Likely trend for the second half of March
Current projections indicate the establishment of a vast high-pressure system extending initially from Scandinavia into eastern Europe. This pattern would promote a south-easterly airflow across our regions, bringing predominantly calm, dry and seasonally mild conditions.
At a later stage, this high-pressure area is expected to shift gradually westwards, extending from Scandinavia across the North Sea towards the British Isles. Such an evolution would favour a prevailing north-easterly flow over our areas, while maintaining stable and dry weather. Temperatures would generally remain above seasonal averages, confirming a persistently settled and mild end to March.

Weather Outlook for 3-4 weeks
Update – 27 February 2026
Week of 16–22 March: continued dry conditions, slightly cooler
The prevailing high-pressure system is expected to persist, maintaining calm and dry weather across the country. However, a gradual shift to a northerly airflow may lead to a slight decrease in temperatures. Even so, values are likely to remain near or slightly above seasonal averages.
Under these stable conditions, marked daily temperature ranges are expected, with cool mornings followed by milder afternoons, a typical feature of March weather.
Week of 23–29 March: possibly more unsettled towards the end of the month
Forecast confidence decreases at this range. The dominant scenario still supports continued high-pressure influence, resulting in largely dry and stable conditions.
However, alternative scenarios suggest a weakening of the high-pressure system, allowing Atlantic disturbances to return towards the end of the month, bringing temporarily more unsettled weather.
In all cases, temperatures are expected to remain above seasonal normals, confirming an already well-established spring-like trend.
***************
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.
