Your guide to what's on in Winchester this month

September 2026 may be 'back to school' season but that doesn't mean the fun is over. As the first signs of autumn appear, Winchester comes alive with a whole host of cultural events and museum exhibitions that'll cure any end-of-summer blues.

We've got plenty of festivals to keep us busy too, from Heritage Open Days - which opens the door to loads of Winchester's fascinating buildings for free - to Winchester Green Week, a celebration of living sustainably and protecting our planet. Not forgetting all the new openings in Winchester to try this month.

While you're filling your diary with things to do in Winchester this September, why not book a table at one of the city's award-winning dining experiences too, or take advantage of Winchester district's pretty picnic spots and alfresco restaurants while the sun still shines.

Enter your pooch into a long-running dog show

Established in 1908, Alresford Show is a one-day celebration of agriculture and rural communities, featuring horse shows, horticultural competitions, vintage farm machinery, a dog show with lots of novelty categories you can enter (dog most like its owner? most adoring eyes?), lots of local food and drink stalls and more.

Explore amazing buildings for free

Winchester is full of interesting buildings. Pretty ones, ancient ones and ones filled with intriguing treasures to discover. This September, a whole host of them, from The Great Hall and Winchester Cathedral to Winchester City Museum and Winchester College are totally free to enter, thanks to the Heritage Open Days 2026 festival, which sees museums, houses and more open their doors to members of the history-loving public. Please note: some buildings are free to visit for the duration of the festival while others are running free tours or events on selected dates.

Practise your downward dog in the park

Bring a yoga mat (or a towel) and enjoy a free hour of alfresco Park Yoga in one of Winchester's green spaces. There's no need to book, you just turn up and stretch it out in the great outdoors. A wholesome way to make the most of the end of the summery days.

Visit an immersive nature festival

Chase a PB at Winchester Half Marathon

They'll then head out for a stretch in the countryside before returning to the city's pretty centre. There's also a 1km Kids Fun Run at 12:30pm for little legs.
