"Sit On the Third Base Side For Shade; Avoid the Outfield"
The best seats at Fenway Park for being in the shade are in the Grandstand, especially on the third base side. These seats are covered from the elements even during early afternoon games. If you want to sit closer to the field, sit on the third base side to get the shade first and to have the sun behind you. Avoid the bleachers at all costs for late afternoon and evening games if you are sensitive to the sun.
