Weather Outlook: Towards Brighter and More Summery Conditions

A south-westerly oceanic flow is currently bringing mild, temperate air across our regions. This precedes a weakening cold front, which is expected to gradually dissipate on Friday over the northern and western parts of the country, bringing at most some marked cloud cover to those areas.

Starting Saturday, the arrival of a well-structured anticyclone (1026 hPa) west of Brittany will mark a turning point. This high will quickly move towards England and the southern North Sea, strengthening slightly to 1028 hPa, and establishing stable, dry and increasingly sunny conditions.

🔆 From Sunday onwards, this system will set up a dry continental flow, ushering in a promising spell of summer weather. Early next week, temperatures will rise further under the influence of a thermal low moving from south-west France towards England. This will draw a surge of very warm Mediterranean air into our regions.

🌩️ On Tuesday evening, a storm front is forecast to cross the Benelux. However, its intensity may remain limited due to the dry air mass ahead of the system, reducing its thunderstorm potential.

METEOCONSULT

BENELUX:

🔎 3–4 week outlook

Update: 31/07/2025 

Late August under tension: heavy heat, then a stormy turn?

🔶 August 16 to 24:
A persistently warm, at times muggy spell may set in, amid growing atmospheric instability. Although the forecast models diverge significantly, one signal remains consistent: a warm air mass lingering over our regions.
Atlantic disturbances might try to edge in from the west, sparking a thunderstorm risk later in the period – a possibility to monitor closely.

🌩️ Week of August 25 to 31:
A sharp shift in weather is looking increasingly likely. Most models suggest a rapid cool-down from the Atlantic, with fresher air clashing with the residual heat. This could trigger intense thunderstorms and mark a turbulent, dramatic end to the meteorological summer.

Update 25-7-25 

Weather Outlook for 3 months

August:  warmth, without extreme peaks

August is expected to remain decidedly summery, with temperatures regularly exceeding seasonal norms, especially from mid-month onwards.
While extreme heat spikes will be less intense than earlier this summer, frequent warm spells are still likely.
A slight rainfall surplus (+10%) is expected, mainly due to isolated thunderstorm episodes, typical of occasional atmospheric instability.
This outlook aligns well with both our earlier forecasts and the latest ECMWF seasonal projections, which favour moderate warmth with intermittent instability.
🔶 Probability of a warm scenario: 70%.

September: Gradual transition to a drier, slightly cooler early autumn

Residual warmth will gradually ease off, although temperatures should still remain slightly above average.
A 10% rainfall deficit suggests drier and more stable weather, under the influence of moderate oceanic air masses.
🔶 The warm scenario remains dominant (55%), though the likelihood of a more normal scenario increases as autumn takes hold.

October: Mild and dry under high pressure influence

October should bring calm, autumnal weather, with temperatures near or slightly above average.
A significant rainfall deficit (−20%) points to a dry and anticyclonic pattern, with weak weather systems crossing the region.
🔶 The warm scenario remains slightly ahead, but normal (40%) and cooler (15%) alternatives cannot be ruled out.
