Climate Guides

Climate Insight: Phoenix Deer Valley Muni, AZ

An annual average temperature of 73°F, ranging from a mean daily high of 84°F to a mean daily low of 61°F is what the NOAA 1991–2020 climate normals report for Phoenix Deer Valley Muni, Arizona. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USW00003184 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. Phoenix Deer Valley Muni sees about 8.9 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 351 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near January 8 and the first fall freeze near December 25. On the energy side, 1,202 heating degree days and 3,963 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Phoenix Deer Valley Muni scores 75/100 (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, 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.
