What Indiana Dunes NL's climate means for you
Indiana Dunes NL runs 50°F a year - peaking in July, coldest in January.
These are 30-year NOAA normals (1991–2020) - the typical year, not a forecast for any specific season.
In Indiana Dunes NL, Indiana, the NOAA 1991–2020 climate normals put the annual average temperature at 50°F, ranging from a mean daily high of 58°F to a mean daily low of 42°F. July is typically the warmest month of the year, while January is the coldest. As thirty-year averages computed from station USC00124244, these numbers smooth out year-to-year noise into a working baseline for a typical month.
Anyone planning to live, garden, or travel in Indiana Dunes NL should weigh precipitation alongside temperature: the annual average runs 39.2 inches, with 40.3 inches typically falling as snow. The frost-free season averages 188 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 22 and the first fall freeze near October 27. And on the energy front, 6,171 heating degree days and 808 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Indiana Dunes NL scores 63/100 (Good), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. The monthly tables above turn that into a planning tool: expect the mildest highs and lows in the shoulder seasons, July-driven heat at the peak of summer, and January-driven cold at the depth of winter. Every number here is a thirty-year average, not a forecast, so any given year can and does run warmer, cooler, wetter, or drier than the normal.
