What Holbrook's climate means for you
Holbrook runs 57°F a year - peaking in July, coldest in December.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
Based on station USC00024089 feeding NOAA's 1991–2020 climate normals, Holbrook, Arizona averages 57°F a year, ranging from a mean daily high of 73°F to a mean daily low of 40°F. July is typically the warmest month of the year, while December 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.
Beyond temperature, Holbrook averages 8.1 inches of precipitation annually, with 3.3 inches typically falling as snow - a real factor for anyone planning to live, garden, or travel here. The frost-free season averages 185 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 22 and the first fall freeze near October 24. Turning to energy use, 4,269 heating degree days and 1,237 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Holbrook scores 63/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. For planning purposes, look to the monthly tables above: shoulder seasons bring the mildest highs and lows, summer brings July-driven heat, and deep winter brings December-driven cold. Treat every figure here as a thirty-year average rather than a forecast - individual years routinely run warmer, cooler, wetter, or drier than the normal.
