You'll find the foliage in autumn particularly appealing, with vibrant colours across the landscape. Travellers who enjoy outdoor activities and scenic drives will appreciate these seasons the most.Summer (July and August) is also a good time, especially for families. The weather is warm, superb for visiting local parks or enjoying events like the Sterling Fair nearby. However, it can be hotter and more humid, so plan your outdoor activities for the mornings or evenings.Winter (November to April) can be cold with snow, which might appeal to those interested in winter sports at nearby Wachusett Mountain.
