This report graphically illustrates the historical weather reports recorded by the weather station at Sendai Airport in the fall of 2021.

METAR Reports

Airport weather stations throughout the world routinely issue METAR weather reports . Such reports are used by pilots, air traffic controllers, meteorologists, climatologists, and other researchers. They are published via radio transmission and on the internet. We have been collecting and archiving published METAR reports since 2011, and have found third-party sources for archived reports from years prior to that.

ISD Reports

The Integrated Surface Database (ISD), maintained and published by NOAA's National Center for Environmental Information , consists of hourly and synoptic weather reports from a variety of sources. We use ISD data to complement and backfill for our METAR archive.

Other Data

The sources for the averages shown in the daily temperature chart are discussed in greater detail on this station's Averages Report.

All 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.

Names, locations, and time zones of places and some airports come from the GeoNames Geographical Database .

Disclaimer

The information on this site is provided as is, without any assurances as to its accuracy or suitability for any purpose. Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
