Jasper, Indiana climate
Winter cold and summer humidity both belong in the Jasper home decision
National Weather Service Evansville normals for 1991 through 2020 provide a nearby Southern Indiana reference: January averages 41.7 degrees Fahrenheit for the high and 25.5 degrees for the low, while July averages 88.6 degrees for the high and 68.8 degrees for the low. The station records 47.91 inches of annual precipitation and 10.8 inches of annual snowfall. Jasper may differ from the station, so use these values as regional guidance rather than a property forecast.
Published climate measures place Jasper in a warm band and list humidity at 93 percent. That combination asks more of heating, air conditioning, insulation, windows, roof, gutters, drainage, snow removal, power, and indoor comfort than a short summer visit reveals. Pair the Riverwalk, parks, arts, and errands with indoor choices for heat, rain, ice, storms, and low energy days.
