Fort Wayne's UV Climate
Fort Wayne sits at the confluence of three rivers in northeastern Indiana, with a classic Midwest UV profile: modest for much of the year, then genuinely strong through the heart of summer. The city's riverfront development, extensive trail network, and TinCaps baseball summers pull residents outside exactly when the UV index peaks, and the region's frequent cloud cover breeds a complacency that clear July days punish.
