Roof Guidelines

The decision for the roof to be opened or closed during Blue Jays games is dependent upon information obtained from several weather service sources. If the game begins with the roof open, the roof can be closed at any time if climatic conditions warrant. If the game begins with the roof closed, it may still be opened before the end of the sixth inning if the Umpire Crew Chief and Blue Jays officials agree the weather has turned in a way that will ensure fan comfort and enjoyment. The Blue Jays strive to make Rogers Centre an "outdoor" facility by having the roof open as often as possible. However, the comfort of our guests is a high priority and is always taken into consideration.

Below are some of the factors taken into consideration before reaching a decision to close the roof at Rogers Centre.

Temperature

  • Forecast temperatures will be below 10 degrees Celsius.
  • Past experiences have demonstrated that fan comfort may be effected by temperatures between 10 and 15 degrees Celsius -- therefore forecasted temperatures at the start and end of the game will be factored into their decision

Wind

  • Winds will be in excess of 64 km/h - 10 minute average wind speed (Design condition)
  • Winds above 20 km/h will also have a cooling effect reducing temperatures below our 10 to 15-degree threshold

Rain

The risk of rain is great (i.e. > 75%)
