What happens if it rains during Boston Calling 2025?

Boston Calling 2025, set for May 23–25 at the Harvard Athletic Complex, operates on a rain-or-shine basis, meaning performances go ahead unless severe weather (e.g., lightning, high winds) poses a safety risk to the 40,000+ attendees.

May in Boston can be unpredictable—averaging 60–70°F with a 40% chance of rain—so past festivals have seen muddy fields and poncho-clad fans rocking out to acts like Foo Fighters in 2023. Organizers won’t cancel for light rain; stages are outdoor (even the new rotating main stage), and the show rolls on with minor delays if needed. If severe weather triggers a pause, updates will flash via the festival app, social media (@bostoncalling), and onsite screens—think temporary evacuations to nearby shelters like Harvard Stadium.

Full cancellation is rare and only happens if conditions persist, triggering Ticketmaster refunds. Bring rain gear (ponchos, waterproof shoes—no umbrellas, as they’re banned) and a clear bag for essentials, per venue rules. Comfort areas with water stations, added for 2025, offer some relief.
