Londoners heading out for Halloween on Saturday, October 31, can look forward to a largely dry night, according to the Met Office forecast for the capital.
Halloween falls on a Saturday this year, and the forecast suggests a mixture of sunshine, mist and cloud across London through the day, with no widespread rainfall currently expected.
The chance of rain on October 31 is currently put at less than five per cent throughout the day. In other words, the forecast leans firmly dry — though, as with any outlook several days ahead, it remains subject to change.
How the day shapes up
Some fog could develop early in the morning, the Met Office says, before conditions brighten through the day. Mist early on is expected to give way to sunshine by late morning, with sunny spells continuing into the afternoon.
By the evening, the picture turns partly cloudy, and temperatures fall again as the night goes on. That matters for anyone spending hours outdoors, whether at a party, an outdoor event or out trick-or-treating with children.
Afternoon highs are expected to reach around 13C, with overnight lows of around 8C. A daytime high of 13C is relatively typical for late October, but the cooler evening could feel chilly for families out for a long stretch, so a warm layer beneath a costume would be a sensible choice.
Fog possible across the wider weekend
The Met Office has also warned that fog could develop across parts of England and Wales over the Halloween weekend. Its weekly outlook points to high pressure keeping much of southern England dry, with light winds allowing mist, low cloud and fog to form, and reduced visibility possible, particularly in the mornings.
That is worth keeping in mind for anyone travelling early in the day, as well as for drivers heading home late after Halloween events.
It is worth noting that other weather providers indicate a possibility of morning showers. That is not the Met Office position, which keeps the chance of rain below five per cent all day, but it is a reminder that the forecast can still shift before Saturday.
Planning the night
For families planning trick-or-treating, the evening looks set to be dry but chilly and partly cloudy — good news for costumes, less good news for anyone out without an extra layer. Torchlight and reflective details will help children stay visible if mist or fog lingers into the evening.
Anyone travelling across London over the weekend should also check their route in advance: the Piccadilly line is shut all weekend, which could affect journeys to and from Halloween events.
And for those looking for somewhere to go, a Coulsdon home turned into a Victorian graveyard — complete with a haunted woods walk — is one of the capital’s more elaborate Halloween displays this year.
Because Halloween falls on a Saturday this year, parties and events are spread across the weekend rather than squeezed into a school night — which also means the Saturday-evening forecast matters more than usual for organisers and families alike.
The forecast remains subject to change, so it is worth checking again closer to Saturday before making firm plans.
