Methodology

How the U.S. land temperature anomaly tracks against the global mean since 1900. The current NOAA 1991-2020 normal for Rothsay captures average conditions across the spread shown — the most recent decade is warmer than the 30-year mean.

Warming context — U.S. vs global, with Paris reference lines Anomaly chart from 1900 to 2024. Local series shows warming of 0.11 °C per decade versus a global rate of 0.11 °C per decade (ratio 1.00).

Climate Insight: Rothsay, MN

The NOAA 1991–2020 climate normals describe Rothsay, Minnesota as a location with an annual average temperature of 42°F, ranging from a mean daily high of 52°F to a mean daily low of 32°F. July is typically the warmest month of the year, while January is the coldest. These thirty-year averages, computed from station USC00217149, 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. Rothsay receives roughly 24.8 inches of precipitation each year, with 49.6 inches typically falling as snow. Growing-season length varies with elevation and microclimate, with the last spring freeze near May 5 and the first fall freeze near October 3. For energy use, 8,937 heating degree days and 478 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.

On PlainClimate's composite comfort index, Rothsay scores 52/100 (Moderate), a blended measure that weighs temperature mildness, precipitation moderation, and extreme-weather frequency against one another. Use the monthly tables above to plan around specific windows — shoulder seasons for mild highs and lows, peak summer for July-driven heat, or deep winter for January-driven cold. All figures here are thirty-year averages: any single year may run warmer, wetter, drier, or cooler than the normal, so treat them as planning guidance rather than forecasts.
