What Boston's weather means for nonprofits
Summer peaks run warmer than the winters suggest: about 20 days a year reach 90°F, so give runners a wicking shirt for a race in July, and hold outdoor events from June to September, when highs average 70°F or more. With January averaging a high of 37°F, a midweight crewneck or hoodie gets worn all winter, which makes it a dependable year-end gift for donors and long-serving volunteers. About 44 inches of rain and melted snow a year means a spring or fall event can turn wet and cold at once, so a poly-blend volunteer hoodie that dries faster than heavy cotton is worth the upgrade. About 49 inches of snow fall in a typical winter, so plan winter fundraisers for indoor venues and save the outdoor walk for the snow-free months. With about 121 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.
