A new Met Office yellow weather warning for fog comes into force across Bristol and the wider South West at midnight on Saturday 7 November, running until around 10am on Sunday 8 November, with forecasters warning that flights, buses and trains could face delays or cancellations.
This is a separate warning to the one that covered Friday night into Saturday morning, which affected London, the South East and the Midlands but did not extend to the South West. Bristol was not under a fog alert for that earlier spell.
According to the Met Office's official warning, "Patchy, dense fog is expected to develop during Saturday night with the visibility falling to less than 50 metres in places. Fog is expected to become increasingly widespread within this area during the second half of the night before only slowly clearing during Sunday morning; slowest across parts of the West Country and central southern England."
The warning lists Bristol by name among the South West areas affected, alongside Bath and North East Somerset, Bournemouth Christchurch and Poole, Devon, Dorset, Gloucestershire, North Somerset, Somerset, South Gloucestershire, Swindon and Wiltshire. Parts of the East Midlands and West Midlands are also covered.
Bristol Live, which spoke to the Met Office directly, reported on Saturday afternoon that the fog is expected to be "patchy" and "dense in places," with visibility potentially dropping below 100 metres in the worst-affected spots before clearing through Sunday morning.
Fog is one of the most common causes of knock-on delays at airports because reduced visibility forces air traffic control to space aircraft further apart on approach and departure, cutting the number of movements an airport can handle per hour. Even where flights are not cancelled outright, a warning like this one can produce delays that ripple through Sunday's schedule as aircraft and crews fall behind their normal rotations.
As of Saturday afternoon, Bristol Airport's own published schedule was running as normal and no cancellations tied to this warning had been confirmed by the airport or individual airlines. The Met Office's "moderate impact" rating reflects a 50 to 75 percent likelihood of disruption rather than a certainty, and the forecaster has said it will keep the warning under review as conditions develop overnight.
Passengers flying from or into Bristol Airport on Sunday morning should check their flight status directly with their airline before setting off, since fog-related delays can appear, worsen or clear within a short window overnight.
What this means for your journey: if you are driving to Bristol Airport on Sunday morning, build in extra time in case of fog on the roads and reduced visibility, and check your airline's app before you leave.
