Does the weather affect Broadway attendance?
Yes — more warmth goes with higher how full theatres are.
Across 1255 weeks, each extra degree (°F) lines up with about 0.05 capacity points more in how full theatres are.
The evidence
Correlation r = 0.1 (95% confidence range 0.05 to 0.16), based on 1255 weeks.
How we measured it
We compare weekly averages and check the link is bigger than random noise. Based on 1,255 data points. This is a pattern we spotted, not proof. Plenty of other things move these numbers too — the time of year, which shows are playing, ticket prices — so treat it as a clue, not a rule.
