What Lafayette Purdue Univ's climate means for you
Lafayette Purdue Univ runs 51°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.
An annual average temperature of 51°F, ranging from a mean daily high of 61°F to a mean daily low of 42°F is what the NOAA 1991–2020 climate normals report for Lafayette Purdue Univ, Indiana. July is typically the warmest month of the year, while January is the coldest. That baseline comes from station USW00014835 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. Lafayette Purdue Univ sees about 37.0 inches of precipitation a year, predominantly as rainfall. The frost-free season averages 175 days, which directly shapes the planting calendar and growing potential for the area, with the last spring freeze near April 26 and the first fall freeze near October 18. On the energy side, 5,824 heating degree days and 883 cooling degree days tell the story of how often furnaces and air conditioners run during a normal year.
On PlainClimate's composite comfort index, Lafayette Purdue Univ scores 64/100 (Good), 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.
