The leaves are turning brown, the weather’s getting chillier and it’s time for a bumper crop of autumn art exhibitions in London.

Two major shows open this week: the British Museum’s Grayson Perry exhibition, which combines new work with objects chosen by Perry from the museum’s collection, and Tate Modern’s retrospective of Gerhard Richter, marking the German artist’s 80th birthday.

Tacita Dean’s installation for The Unilever Series is unveiled in Tate Modern’s Turbine Hall on 11 October. Chinese artist Ai Weiwei covered the hall in ceramic sunflower seeds for last year’s commission. We can’t wait to find out what Dean has in store!

Frieze Art Fair returns to Regent’s Park in mid-October, bringing together 170 of the best art dealers from around the world, along with arty talks, films, music, installations and a sculpture park.

Wildlife Photographer of the Year returns to the Natural History Museum, displaying the best wildlife images chosen from 41,000 submissions. And then, in November, one of this year’s most anticipated exhibitions opens: Leonardo da Vinci at the National Gallery, which is sure to be another London blockbuster.
