Last updated: 30 October 2026, 09:40 GMT. Warning status rechecked: Brighton remains outside the separate alert affecting journeys further north.
Our Brighton fog warning check on Friday 30 October found no warnings in force for the city, while a yellow fog warning covering parts of England, including Surrey and Hampshire, was scheduled to run until 10am GMT. For Brighton residents travelling out of Sussex this morning, the useful check is the whole journey, rather than the weather at the front door.
Brighton fog warning check: where the alert applies
The Met Office’s UK warning, issued at 04:18, describes fog with visibility below 100 metres in places. It says the most extensive disruption is expected during the morning rush hour, with fog thinning later in the morning and potentially lingering into the afternoon in some rural eastern areas.
The published affected-area list includes Surrey, Hampshire and several counties further north and east. An area’s inclusion does not establish poor visibility on every road within it. Conversely, the absence of a Brighton warning is not a guarantee of clear conditions at every point locally.
What travellers should do
Open the warning map and check the places your journey passes through. If travelling by train or flying, check your operator’s live departure information before leaving; this report does not establish that a particular service is delayed.
The Department for Transport’s Highway Code, rules 226 and 234–236, says to slow down before entering fog and use headlights when visibility is seriously reduced, generally below 100 metres. Fog lights must be switched off when visibility improves.
Brighton Locals’ view
A warning boundary is useful information, but a poor substitute for checking a journey. Calling this a Brighton fog warning would overstate the evidence. Ignoring it simply because Brighton is outside the alert would be equally unhelpful for someone heading into an affected area.
What happens next
The next checkpoint is the scheduled 10am expiry. Use the live Met Office page for any extension or change; an expiry time should not be treated as a promise that all fog instantly disappears. Our half-term weather report provides the separate local outlook.
Bottom line: Brighton is outside this alert, but a journey from Brighton may still cross it.
