Almost all non-lawn seats at DTE Theatre are covered by the roof. Exceptions include sections ending in 10 or 11 (e.g.: Left 10, Right 11, etc.). In sections ending in 10 or 11, a small number of seats are not covered.
While the roof will keep you dry in most seats, the sun does find its way into some sections during the early evening hours. To avoid any glare, skip sections RT (Right) 3-11 and choose something towards the left or center of the amphitheatre.
