Please note that each source's contribution is adjusted for elevation and the relative change present in the MERRA-2 data.Īll data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition, by Jean Meeus.Īll other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis. To get a sense of how much these sources agree with each other, you can view a comparison of Columbus and the stations that contribute to our estimates of its temperature history and climate.

There are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Columbus.įor each station, the records are corrected for the elevation difference between that station and Columbus according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
This report illustrates the typical weather in Columbus, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. Our beach/pool temperature score is 0 for perceived temperatures below 65☏, rising linearly to 9 for 75☏, to 10 for 82☏, falling linearly to 9 for 90☏, and to 1 for 100☏ or hotter. Our tourism temperature score is 0 for perceived temperatures below 50☏, rising linearly to 9 for 65☏, to 10 for 75☏, falling linearly to 9 for 80☏, and to 1 for 90☏ or hotter. Our precipitation score, which is based on the three-hour precipitation centered on the hour in question, is 10 for no precipitation, falling linearly to 9 for trace precipitation, and to 0 for 0.04 inches of precipitation or more. Our cloud cover score is 10 for fully clear skies, falling linearly to 9 for mostly clear skies, and to 1 for fully overcast skies. Those scores are combined into a single hourly composite score, which is then aggregated into days, averaged over all the years in the analysis period, and smoothed. The beach/pool score (filled area), and its constituents: the temperature score (red line), the cloud cover score (blue line), and the precipitation score (green line).įor each hour between 8:00 AM and 9:00 PM of each day in the analysis period (1980 to 2016), independent scores are computed for perceived temperature, cloud cover, and total precipitation. The coldest month of the year in Columbus is January, with an average low of 24☏ and high of 38☏.Īverage High and Low Temperature in Columbus The cold season lasts for 3.0 months, from December 1 to March 1, with an average daily high temperature below 47☏. The hottest month of the year in Columbus is July, with an average high of 85☏ and low of 67☏.
