London's weather changes from cold and damp in winter to bright and warm in the summer. Here's what you can expect to find throughout the year.
Spring (Mar - May)
Quite unpredictable with a good mixture of sun, rain and cloud. Temperatures average between 11°C and 15°C. Take a jacket when you go out.
Summer (Jun - Aug)
Generally sunny, with the occasional rainstorm. Temperatures average around 20°C, but have been known to go as high as 37.9°C.
Autumn (Sep - Nov)
Pretty much the same as spring. However it's not unknown for summer to run well into September or for November to be uncharacteristically cold. So be prepared.
Winter (Dec - Feb)
Temperatures hover around 6°C and it's normally mild but damp. It rarely freezes or snows in London, but you'd be wise to take a hat and gloves when going out.
