State Farm Stadium Weather: Retractable Roof, Arizona Heat

By Kevin Roth, sports meteorologist. Stadium weather guide for DFS players and bettors.

Climate

The Cardinals play in a retractable-roof stadium in Glendale, Arizona. Roof status is driven by extreme September heat baseline and moderating through late season.

How wind and weather play here

With the roof closed, no wind. With the roof open, desert wind reaches the field under prevailing patterns.

Roof behavior

State Farm Stadium's roof closes for early-season games because of Phoenix-area heat. Late-season games with cooler evenings see the roof open more often.

For DFS and bettors

Roof status is the leverage. September games with heat index above 100 outside are almost certainly closed-roof environments. Late-season roof-open games are the true outdoor Cardinals conditions.
