Boca averages 22.5 inches of precipitation a year, with 98.4 inches typically falling as snow, and that matters as much to daily life here as temperature does. Growing-season length varies with elevation and microclimate. As for energy demand, 7,581 heating degree days and 59 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Boca scores 47/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and January-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
