Climate Insight: Miami, AZ
Miami, Arizona runs an annual average of 67°F, ranging from a mean daily high of 81°F to a mean daily low of 53°F, per NOAA's 1991–2020 climate normals. July is typically the warmest month of the year, while December is the coldest. Drawn from station USC00025512, these thirty-year averages smooth out year-to-year swings into a baseline for what a typical month looks like here.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Miami sees about 17.2 inches of precipitation a year, with negligible snowfall. The frost-free season averages 280 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near February 24 and the first fall freeze near December 1. On the energy side, 2,053 heating degree days and 2,758 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 87/100 (Excellent), 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, July-driven heat at the peak of summer, and December-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.
