Ballpark weather FAQs

Yes. The river creates a channel that steadies the wind direction along the right-field line and can make the in-stadium breeze cooler and stronger than the downtown forecast.

It leans pitcher-friendly, especially at night. The deep alleys and cool river air suppress extra-base hits, so a total usually needs warm, calm conditions to move Over.

April and September night games are the main movers. Cold air off the river plus a steady breeze is the classic Under combination, while warm, still summer evenings play closer to neutral.
