best months

BooJum Rock Area is a climbing area in the Middlesex Fells of Massachusetts, about half a mile from the community of Malden Highlands. It sits among a cluster of crags and trails, with Crag 1, also known as Pinnacle Rock, just 0.2 miles away and Crag 3 about 0.3 miles off. The Cross Fells Trail and Rock Circuit Trail are also within a third of a mile, making it easy to pair a climb with a walk. The area is a bouldering destination, with five routes listed, four of them boulders and one a top-rope climb. The boulders range from V0 to V2 on the V scale, and the top-rope route is graded 5.9+ on the YDS scale. The Arete is the hardest of the boulders at V2, while Left Arete and RL Traverse are both V0. For timing, late spring and early fall are the most comfortable. Typical averages from a nearby weather station in Reading show May highs around 70°F and September highs around 75°F, with July the warmest month at about 84°F. Winter brings regular snow, with January highs near 38°F and about eight snow days. Other climbing areas close by include Crag 6, also known as Black Rock, and The Cove, both about 0.4 miles away.
