Notes:

  • The above data, with the exception of normals, are produced by a private weather station located 1/4 mile south of downtown Marquette. The station went online July 10, 2015.
  • If you're seeking official weather data for the Marquette COOP station (1857 - present), please visit NOAA NOWData.
  • Graphs along with daily and monthly history tables are updated every 5 minutes. Yearly histories are updated at the top of every hour.
  • "NWS" averages are the sum of the daily high temperature & daily low temperature in whole degrees divided by 2. This is the National Weather Service method used for climatological summaries. All other fields labelled "Avg" contain integrated averages using one minute samples. "Avg" labelled summary columns contain weighted means (i.e. a partial hour/day/month counts less than a full one).
  • CDD = Cooling Degree Days & HDD = Heating Degree Days. Degree days are calculated using daily integrated averages of 1 minute samples compared to a base value of 65°. For example, a day with an avg temperature of 67.7° will have 2.7 CDDs & 0 HDDs. A 33.2° avg temperature will produce 31.8 HDDs & 0 CDDs.
  • "Wind Dir" is a scalar average of direction irrespective of speed. However, calm winds do not have a valid direction and are not included in the average.
  • "Wind Run" uses the 10 minute wind average.
  • "Low 10 Min Avg" & "Low Max" wind values are omitted from the yearly history table since every field equals 0.
  • In the daily & monthly history tables, "Wind Chill" appears only October through April. It is calculated when the temperature is 45 or below and average wind speed is at least 3 mph. Otherwise, it equals the temperature. Likewise, "Heat Index" appears only May through September. It is calculated only when the temperature is 80 or above. Otherwise, it equals the temperature.
  • As of July 2018 daily, monthly, and yearly history tables contain corrected humidities and dew points. A custom correction curve addresses a dry bias above 95% and a wet bias below 92% inherent to the sensor. A third-party device accurate to within 2% humidity established the deltas used in the algorithm. The daily table contains up-to-date corrections for today. The monthly and yearly tables have corrections through yesterday (updated just after midnight each morning).
  • "Liquid" precipitation in the winter is the amount of melted snow and/or ice.
  • Snow measurement began in October 2017.
  • The daily precipitation table doesn't contain hourly reports because often we correct the total with a measurement from our manual gauge. Unfortunately, when that happens, we have no way of reconstructing hourly amounts. For a raw, uncorrected breakdown of rain over the past 24 hours please see the precipitation graph at the top of the page.
  • Humidity and dewpoint are corrected in all tables according to a custom calibration curve. 24 hour graphs contain uncorrected values.
  • Since January 15, 2018, pressure is recorded in altimeter format. The home page, however, continues to display "Barometer" in MSLP format by default.
  • "Depart" in the Normals table refers to the average departure (or difference) between our weather station and the official Marquette average temperature recorded at the Waste Water Treatment Plant on Lakeshore Dr. These numbers are updated monthly based on data beginning August 2015 (first full month of data collection).
