Warming context for Miami
MethodologySince 1900, U.S. land temperatures have tracked (and diverged from) the global mean - the chart below shows how. Miami's current NOAA 1991-2020 normal sits within that longer spread, and the most recent decade runs warmer than the 30-year mean.
- United States land mean (NOAA NCEI) +0.11 °C/decade
- Global anomaly (NASA GISTEMP) +0.11 °C/decade
- Paris Agreement thresholds 1.5°C / 2.0°C

Climate Guides
Climate Insight: Miami, FL
Based on station USW00012839 feeding NOAA's 1991–2020 climate normals, Miami, Florida averages 77°F a year, ranging from a mean daily high of 84°F to a mean daily low of 71°F. August is typically the warmest month of the year, while January is the coldest. Because these figures are thirty-year averages rather than any single year's readings, they describe the typical month, not a forecast for it.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Miami sees about 67.4 inches of precipitation a year, with negligible snowfall. Growing-season length varies with elevation and microclimate. On the energy side, 104 heating degree days and 4,656 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Miami scores 62/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, August-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
