The best time to go to Jonesborough is during the summer months, from June to August, when the weather is generally mild and pleasant.During these months, you'll experience longer daylight hours, which is ideal for exploring the local countryside and historic sites like the Moyry Pass. The temperatures are comfortable for outdoor activities such as walking the scenic trails or visiting the Ring of Gullion AONB, making it superb for those who enjoy being outdoors without extreme heat or cold.Spring (April to May) and autumn (September to October) also offer agreeable conditions. In spring, the landscape is particularly fresh and green, while autumn brings beautiful foliage.
