Warming context for Valdez

Methodology

Since 1900, U.S. land temperatures have tracked (and diverged from) the global mean - the chart below shows how. Valdez's current NOAA 1991-2020 normal sits within that longer spread, and the most recent decade runs warmer than the 30-year mean.

Climate Guides

Climate Insight: Valdez, AK

An annual average temperature of 37°F, ranging from a mean daily high of 44°F to a mean daily low of 30°F is what the NOAA 1991–2020 climate normals report for Valdez, Alaska. July is typically the warmest month of the year, while December is the coldest. That baseline comes from station USC00509687 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. Valdez sees about 82.1 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 131 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 14 and the first fall freeze near September 22. On the energy side, 10,267 heating degree days and 1 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Valdez scores 34/100 (Below Average), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above are the practical planning tool: mild highs and lows land in the shoulder seasons, July-driven heat peaks in summer, and December-driven cold sets in over deep winter. These are thirty-year averages, not a forecast - any single year can run warmer, wetter, drier, or cooler than the normal.
