Weather along the trail is typical of Massachusetts; however, conditions on exposed hilltops and mountaintops can be much harsher in bad weather. In the winter and early spring, ice is a common danger on steep slopes and ledges, sometimes making portions of the trail unhikeable without special equipment. Deep snow in the winter may necessitate snowshoes or skis. Snow and ice may cling to parts of Mount Wachusett and Mount Watatic longer than it does in the surrounding area. Lightning can be a hazard on exposed peaks and hilltops during summer thunderstorms.
