The best time to go to Abergavenny is during the late spring and summer months, from May to September, when the weather is generally at its finest.This period offers the warmest temperatures and the most sunshine, making it ideal for exploring the Black Mountains and Brecon Beacons National Park. You'll find conditions superb for walking, cycling, and enjoying the outdoor activities the area is known for. Many local events, including the Abergavenny Food Festival, also take place during these months.For those who prefer a quieter visit and don't mind cooler weather, late April and early October can also be lovely. The landscapes are often spectacular with spring blossoms or autumn colours, and there are fewer crowds.
