![]() ![]() We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. We assume no responsibility for any decisions made on the basis of the content presented on this site. Weather data is prone to errors, outages, and other defects. The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Time zones for airports and weather stations are provided by. Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database. Land Use data comes from the Global Land Cover SHARE database, published by the Food and Agriculture Organization of the United Nations.Įlevation data comes from the Shuttle Radar Topography Mission (SRTM), published by NASA's Jet Propulsion Laboratory. This reanalysis combines a variety of wide-area measurements in a state-of-the-art global meteorological model to reconstruct the hourly history of weather throughout the world on a 50-kilometer grid. Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.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. The station records are corrected for the elevation difference between the station and Cancún according to the International Standard Atmosphere, and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. There is only a single weather station, Cancún International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Cancún.Īt a distance of 16 kilometers from Cancún, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records. This report illustrates the typical weather in Cancún, based on a statistical analysis of historical hourly weather reports and model reconstructions from Januto December 31, 2016. ![]()
