Built to withstand the heat, Q2 Stadium was built to help keep fans cool. Most seats at the stadium are under the uniquely shaped roof. While this cover won't necessarily keep you shaded (or even dry on a rainy day), it provides shade in a number of seating areas and non-seating areas.
In general, the best place for shade at Q2 Stadium is the west sideline. This includes sections 309-317 in the upper level and club and fieldside seats in the lower level. The sun sets behind these seats which leaves them shaded before the rest of the stadium. A middle section in these areas will get you a better view and also ensure that the sun doesn't creep in from the corner of the stadium.
The east sideline is just as well covered as the west side. At mid-day when the sun is over-head, both sides have equitable shade. But as the sun starts setting in the south and west sides, the east sideline is susceptible to the sun - especially sections 233-236 and 133-137.
