The overhang at Hard Rock Stadium provides cover to all of the upper level and half of the lower level. In the lower level the overhang extends out to row 12. However, when sitting in the sideline and endzone sections it's better to find seating in rows 15 or higher in case of inclement weather.
The overhang at Hard Rock Stadium will provide good shade to a lot of the sections, as well as protection from inclement weather. However, if it is raining hard, not all rows will be protected, so it is better to sit in the higher rows, especially in the lower level.
