July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USW00026425, smooth out year-to-year variability and give a baseline expectation for typical conditions in any given month.
Precipitation patterns matter as much as temperature for anyone planning to live, garden, or travel here. Gulkana receives roughly 11.8 inches of precipitation each year, predominantly as rainfall. The frost-free season averages 75 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near June 7 and the first fall freeze near August 21. For energy use, 13,377 heating degree days and 8 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Gulkana 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 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.
