Overview of the Pink Fog Phenomenon
On Wednesday, December 17, 2025, many residents in London and the southeast of England experienced a rare weather phenomenon known as "pink fog." This occurs when sunlight passes through layers of fog, scattering shorter wavelengths of light and allowing longer red wavelengths to dominate, resulting in a pinkish hue in the sky. Graham Madge, a spokesperson for the Met Office, explained that this effect is akin to a sunrise filtered through the atmosphere and fog, dependent on local conditions.
Impact on Travel and Weather Warnings
The pink fog coincided with significant weather disruptions, as the Met Office issued yellow weather warnings for fog and rain across various regions. Visibility was reported to be as low as 100 meters in some areas, leading to the cancellation of seven flights at London City Airport and delays for flights inbound to Southampton. The Met Office warned that the fog could lead to difficult travel conditions, particularly in the east Midlands and Cambridgeshire.
In addition to fog, heavy rain warnings were also in effect. The Met Office predicted that rain would push eastward on Thursday, with yellow warnings for rain across south-west England and south Wales until 7 PM. Accumulations of 15 to 25 mm were expected widely, with localized totals of 40 to 60 mm possible over the Downs.
Broader Weather Context
The unusual weather patterns are attributed to low-pressure systems moving across the UK, bringing unsettled conditions. Neil Armstrong, chief forecaster at the Met Office, indicated that the week would remain unsettled, with further rain likely leading to increased flooding risks. The Environment Agency has issued multiple flood alerts, particularly in areas like Cumbria and south Wales, where homes and businesses are at risk of flooding due to heavy rainfall.
Criticism and Concerns
While the pink fog provided a visually stunning spectacle, it also raised concerns about the potential dangers associated with reduced visibility and flooding. The Environment Agency urged the public to avoid driving through floodwaters, emphasizing that even shallow water can pose significant risks.
