What John Day's climate means for you
John Day runs 53°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.
In John Day, Oregon, the NOAA 1991–2020 climate normals put the annual average temperature at 53°F, ranging from a mean daily high of 65°F to a mean daily low of 40°F. July is typically the warmest month of the year, while December is the coldest. As thirty-year averages computed from 2 weather stations, these numbers smooth out year-to-year noise into a working baseline for a typical month.
Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. John Day sees about 9.8 inches of precipitation a year, with seasonal snowfall possible. The frost-free season averages 167 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 30 and the first fall freeze near October 14. On the energy side, 5,149 heating degree days and 690 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, John Day scores 44/100 (Moderate), 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.
