Going to a Diamondbacks day game at Chase Field? In Phoenix's extreme summer heat, the retractable roof is essentially always closed and the park air-conditioned, so sun just isn't a factor; every seat is shaded and cool. On the rare open-roof game, the third-base side holds the most shade.

At Chase Field the roof is the whole story: in Phoenix's 110°+ summer heat, it's essentially always closed and the stadium air-conditioned, so every seat is out of the sun and comfortable. On the rare occasion it's open (usually cooler evenings or the shoulder months), home plate faces roughly north-northeast, so the third-base/left-field side holds the most shade while the first-base/right-field side and the pool area take the most sun.
On the rare open-roof game, these are the share of a typical early-afternoon game each zone holds shade in our 3D model (with the roof closed, nearly always, in a Phoenix summer, every seat is fully shaded):
| Section area | Level | Shaded for… |
|---|---|---|
| Third-base side | Lower & Club | ~82-83% of the game |
| Behind home plate | Lower & Club | ~69-71% |
| Left-field line | Lower | ~68% |
| First-base side | Lower & Club | ~47-53%, more sun |
| Pool & right-field outfield | Outfield | Mostly sun (open roof only) |
Percentages are for a typical 1:10 PM start in midsummer; your exact game may differ. Plug your date and first pitch into the live map for a per-row read.
In a Phoenix summer the roof is closed, so any seat is shaded and cool. For a rare open-roof game:
| Seats | Why they're shaded |
|---|---|
| Any seat, roof closed | In Phoenix's heat the roof is essentially always shut, the whole park is shaded and air-conditioned |
| Third-base side, Lower & Club (open roof) | Orientation shades them longest; ~82-83% |
| Behind home plate, Lower & Club (open roof) | Deck overhang plus orientation |
This only matters on the rare open-roof game: the first-base/right-field side, the pool area, and the upper deck take the most sun. In a normal Phoenix summer, the roof is closed and every seat is shaded and air-conditioned.
Yes. Chase Field has a retractable roof, and in Phoenix's extreme summer heat, routinely 105-115°F, it's essentially always closed with the stadium air-conditioned. Every seat is shaded and cool for a summer day game.
On the rare open-roof game, the third-base/left-field side holds the most shade, around 82-83% of a day game in our model, because home plate faces roughly north-northeast. The first-base/right-field side and the pool area take the most sun.
With the roof closed, nearly always in summer, every seat is shaded and air-conditioned, so pick for the view or price. For a rare open-roof game, the third-base side is coolest.
In a Phoenix summer, Chase Field plays with the roof closed and the AC on, so every seat is comfortable day or night. On a rare open-roof evening, the third-base side holds shade longest. The interactive tool models any start time and the live weather.
Shade predictions come from a 3D ray-traced model of the seating bowl combined with the exact solar position for your date and time; roof-closed games are treated as fully shaded. The bowl geometry is a calibrated approximation, so use the map to pick a side and row range, then confirm the precise seat on a ticket map.

Chase Field ranks #15 of 30 for sun exposure in MLB: the average seat sits in direct sunlight for about 120 of a 190-minute day game, or 63% of it. Full ranking and method in the sunniest seats in baseball.
