General Weather Evolution for the Next 6 Days
Europe: Analysis & Forecast maps (6 days)
Update 13-8-25 at 12 AM – Evolution of the Weather Pattern
Atmospheric evolution
In the coming hours, a small thermal low-pressure core – 1014 hPa – will move from the southwest of France towards central Germany. In its wake, it will carry a few thunderstorm cells, which could already bring isolated showers or a solitary heat storm to our regions this evening.
Behind it, by Thursday afternoon, a high-pressure system (1022 hPa) will form to the west of the English Channel, joining on Friday with a powerful 1031 hPa system near the Scottish coast. Together, they will set up a northerly airflow from the North Sea, pushing the very hot air back towards France.
The weekend will be under their control, with a broad dome of high pressure – 1030 to 1028 hPa – over the northern North Sea, bringing stable, dry air from the north to north-east. Temperatures will remain pleasantly mild, though no longer reaching the heights of recent days.
Then, at the start of next week, the pattern will reverse. From the southwest of France, a new thermal low will develop, gradually dropping to around 1012 hPa and heading for the Channel. It will bring with it a warmer southerly flow, once again enveloping the Benelux. This time, however, the unstable air could trigger a more pronounced outbreak of thunderstorms by midweek.

BENELUX:
🔎 3–4 week outlook
Update: 8-8-2025
22–31 August: return to seasonal conditions
Late August is expected to align closely with seasonal averages, with no major heat spikes. A few disturbances arriving from the English Channel may bring occasional spells of unsettled weather.
1–7 September: possible late-summer resurgence
Early September may see a return to dry and warm conditions, continuing the fine spell of August. While this scenario is not yet certain, there is potential for the first week of September to carry a distinct late-summer feel.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------
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.
