WINAMAC, IN

Overview:
Winamac is located in the northwest region of Indiana. The Tippecanoe River resides to the east of the area, branching off into much smaller rivers and streams nearby. Otherwise, the terrain is mostly flat and developed, with few distinguishing features. The climate of the county provides ample precipitation and favorable temperatures for farming.

Summertime temperatures can get quite hot at times, with temperatures averaging the low-70°Fs, but they exceed 90°F about ten days per year. Wintertime temperatures are frequently cold, with temperatures falling below freezing (32°F) over 100 days per year. Most of the area’s annual precipitation falls during the summer months and early fall. Extreme precipitation events occur infrequently, with just under 1 week per year. Thunderstorms, which are prominent mostly in July, occur about 42 days each year.

Annual High and Low Temperature Departure

Cold Temperatures

¹Heating Degree Days (HDDs) are indexed units, not actual days, that roughly describe the demand to heat a building. HDDs accumulate on days colder than 65°F when heating is required. Every degree below 65°F is added to the annual total for an annual HDD value, which is plotted in the figure.

Hot Temperatures

²Cooling Degree Days (CDDs) are indexed units, not actual days, that roughly describe the demand to cool a building. CDDs accumulate on days warmer than 65°F when cooling is required. Every degree above 65°F is added to the annual total for an annual CDD value, which is plotted in the figure.
