Short answer: The Gringotts dragon in Diagon Alley at Universal Studios Orlando breathes fire roughly every 10 minutes during park hours, with typical intervals reported around 10 to 15 minutes depending on wind and maintenance conditions. It tends to run on a regular cadence, starting at the open of the park and continuing through the day, though weather (wind) and occasional maintenance can cause deviations. Context and details

• Cadence: Most guest reports and social accounts indicate fire bursts occur about every 10 minutes (often on a :00, :10, :20, etc. schedule) while the dragon is active. Windy or windy-like conditions can suppress the effect, and maintenance issues can cause temporary pauses.

• Variability: Several independent sources note a typical window of about 10–15 minutes between flames, with rare interruptions due to wind or mechanical concerns.

• Observation tips: The dragon often emits a rumbling roar shortly before the flame, which can help you time your view without waiting in a fixed position. Standing directly in front of Gringotts Bank is commonly mentioned as a good vantage, though any safe viewing area in Diagon Alley can capture the effect when it occurs.

What might affect the timing

• Wind and weather: Strong winds can prevent the flame from projecting, causing a temporary pause.

• Maintenance: Occasional maintenance or technical hiccups can halt the show briefly.

• Real-time variability: Even with a general cadence, minor day-to-day variations may occur, so the exact times can shift.

Practical tips

• If you want to maximize the chance of seeing a fire burst, plan for a time window around 10 minutes after you arrive in Diagon Alley and stay attentive to the dragon’s roar and rumbling prelude.

• Use the park’s open hours as a baseline; the display is typically active from park opening to close, weather permitting.
