Climate

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.
