Warming context for Gateway

Methodology

The chart below traces how the U.S. land temperature anomaly has moved against the global mean since 1900. For Gateway, the NOAA 1991-2020 normal captures average conditions across that spread - notably, the most recent decade runs warmer than the 30-year mean itself.

Climate Insight: Gateway, CO

The NOAA 1991–2020 climate normals describe Gateway, Colorado as a location with an annual average temperature of 56°F, ranging from a mean daily high of 71°F to a mean daily low of 42°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00053246, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.

Gateway averages 11.8 inches of precipitation a year, with 11.2 inches typically falling as snow, and that matters as much to daily life here as temperature does. The frost-free season averages 184 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 20 and the first fall freeze near October 21. As for energy demand, 4,547 heating degree days and 1,331 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Gateway scores 68/100 (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 January-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.
