Warming context for Ester

Methodology

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

Climate Insight: Ester, AK

Based on 2 weather stations feeding NOAA's 1991–2020 climate normals, Ester, Alaska averages 27°F a year, ranging from a mean daily high of 38°F to a mean daily low of 16°F. July is typically the warmest month of the year, while January 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.

Rainfall (and snow, where it falls) shapes day-to-day life here as much as temperature does. Ester sees about 14.6 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 100 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near May 24 and the first fall freeze near September 1. On the energy side, 13,922 heating degree days and 29 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Ester scores 44/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Shoulder seasons bring the mildest highs and lows in the monthly tables above, summer brings July-driven heat, and winter brings January-driven cold - use that rhythm for planning. These figures are thirty-year averages rather than forecasts, so a specific year may still run warmer, cooler, wetter, or drier than what's shown.
