Climate Insight: Key W, FL
An annual average temperature of 77°F, ranging from a mean daily high of 83°F to a mean daily low of 72°F is what the NOAA 1991–2020 climate normals report for Key W, Florida. August is typically the warmest month of the year, while January is the coldest. That baseline comes from station USC00084571 and thirty years of averaging, so it reflects a typical month rather than any one year's swings.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Key W sees about 46.4 inches of precipitation a year, predominantly as rainfall. Growing-season length varies with elevation and microclimate. On the energy side, 56 heating degree days and 4,574 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Key W scores 77/100 (Good), 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, August-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.
