London forecast, Met Office

Will it rain on Armistice Day?

Wednesday 11 November looks like the wettest day of the week, with light rain most likely early in the morning. It should be easing by 11am, when people stop for the two-minute silence.

When will it get colder?

From Thursday night, clearer skies mean temperatures will drop to around 4–5°C overnight. Days will stay at about 9–10°C, so it is time for a warmer coat in the mornings, especially at the weekend.
