After a dry spell, Friday 21 August brings a more unsettled picture for Richmond. The Met Office is forecasting light rain through much of the day, with a 64% chance of precipitation and a high of 22°C — noticeably cooler than recent days. Overnight temperatures will drop to around 13°C.
The forecast also flags the possibility of a storm, so if you have outdoor plans for tomorrow it is worth keeping a close eye on updates through the day. UV index sits at 5 — moderate — though heavy cloud cover will limit any meaningful sun exposure.
For those commuting or travelling, it is worth leaving a little extra time in the morning and ensuring you have a waterproof to hand. Cyclists planning to use Richmond Park or the riverside paths may want to check conditions before setting out.
