Notes:

General

  • 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 at the top are linked to larger, more detailed views that in some cases add information. These larger versions update every 5 minutes. Smaller graphs are updated every minute.
  • Daily and monthly history tables are updated every 5 minutes. Yearly histories are updated at the top of every hour.

Temperatures

  • "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.
  • In the daily & monthly history tables, "Wind Chill" appears only October through April. It is calculated when the temperature is 45 or below and sustained 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.

Wind

  • "Sustained" wind is the rolling 10 minute average sustained wind speed.
  • "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 Sustained" & "Low Max" wind values are omitted from the yearly history table since every field equals 0.
  • Anemometer (wind gauge) was raised from 20 ft to 28 ft on June 18, 2017

Humidity / Dew Point

  • 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).
  • The smaller embedded 24 hour graphs contain uncorrected humidities & dew points. The detailed, larger graphics (available by clicking image) contain corrected values.

Precipitation

  • "Liquid" precipitation in the winter is the amount of melted snow and/or ice.
  • Daily snowfall record keeping began in October 2017.
  • Starting in the fall of 2019 snowfall measurements for the current season also appear on the Snow Measurements page. This is where you will find break outs of all intraday measurements & estimates when measurement was insufficient or impossible.
  • Snowfall measurements occur as time, health, and weather permits.
  • 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.

Pressure

  • Since January 15, 2018, pressure is recorded in altimeter format. The home page, however, continues to display "Barometer" in MSLP format by default.

Solar

  • UV index measurement began June 6, 2020. Sensor detects ultraviolet radiation at wavelengths of 290 to 390 nm. Scale is 0-16 (but never gets above 11 in Marquette).
  • Solar radiation measurement began June 11, 2020. Scale for solar radiation is 0 - 1800 Watts per meter squared. This measurement of the sun's energy (detected between 300 and 1100 nanometers wavelength) can approximate daylight cloud cover relative to clear days for a given time of year. It's also useful for determining solar electricity generation and aerosol levels (pollution, smoke, dust, ash, etc).
  • The daily table summary footer for this tab omits "Min" since every value is always 0. Instead you'll see a "Daytime Avg" row displaying weighted averages of all hourly maximums, minimums, and averages between sunrise & sunset.
  • In monthly & yearly tables, you'll see a "Daytime Avg" column containing daylight averages. The "Min" column will be entirely missing since every value would be 0.
  • Total Radiation is measured in Megajoules (1,000,000 J) per meter squared.

Normals

  • "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 Water Filtration Plant on Lakeshore Dr. These numbers are updated monthly based on data beginning August 2015 (first full month of data collection).
