Evansville: Geography and Climate
Evansville lies along the north bank of the Ohio River in a shallow valley at the southwestern tip of Indiana. Low hills surround flat, rolling land to the north, east, and west; the valley opens onto the river to the south. The city's climate is determined by moisture-bearing low pressure formations that move across the area from the western Gulf of Mexico region northeastward over the Mississippi and Ohio valleys to the Great Lakes and northern Atlantic Coast. These storm systems, which produce considerable variation in seasonal temperatures and precipitation, are especially prevalent during the winter and spring months. The growing season lasts approximately 199 days.
