What Indianapolis's weather means for nonprofits
Book walks, runs and outdoor volunteer days for May to September, the only stretch with average highs of 70°F or more; outside that window, participant shirts should be long-sleeve. With January averaging a high of 36°F, a midweight crewneck or hoodie gets worn all winter, which makes it a dependable year-end gift for donors and long-serving volunteers. Highs stay under 65°F from November to April, half the year or more, so print the volunteer mark on a hoodie as well as the tee, and offer the hoodie as a fundraising item. About 26 inches of snow fall in a typical year, enough that a winter date can be snowed out, so give any outdoor holiday drive a backup date and keep spare volunteer hoodies at check-in. With about 106 nights a year at or below 32°F, early-morning volunteers in the cold months need a warm layer, so budget a hoodie or fleece for the setup crew as well as the event tee.
