Temperatures will reach highs of 21C tomorrow (Thursday, 20th March) bringing bright sunshine and blue skies to the capital.

The Met Office has said London will be “dry with lengthy sunny spells and gentle winds” on Wednesday (19th March).

It continues: “It will be largely dry and sunny on Thursday and most of Friday. Turning unsettled later on Friday, cloudier with spells of rain, heavy at times.”

Friday and Saturday will remain warm but will bring clouds and the chance of showers. Temperatures will return to ‘normal’ on Sunday with highs of 12C.

In even better news the clocks will go forward this weekend - meaning longer and lighter evenings are on their way!

Next week will see average temperatures and sporadic rain showers throughout the week.
