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.

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.
