Humidity

We base the humidity comfort level on the dew point, as it determines whether perspiration will evaporate from the skin, thereby cooling the body. Lower dew points feel drier and higher dew points feel more humid. Unlike temperature, which typically varies significantly between night and day, dew point tends to change more slowly, so while the temperature may drop at night, a muggy day is typically followed by a muggy night.

The chance that a given day will be muggy in Yangon is essentially constant during January, remaining within 2% of 51% throughout.

The lowest chance of a muggy day during January is 48% on January 11.

For reference, on May 27, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 11, the leasy muggy day of the year, there are muggy conditions 48% of the time.

Wind

This section discusses the wide-area hourly average wind vector (speed and direction) at 10 meters above the ground. The wind experienced at any given location is highly dependent on local topography and other factors, and instantaneous wind speed and direction vary more widely than hourly averages.

The average hourly wind speed in Yangon is essentially constant during January, remaining within 0.1 miles per hour of 3.2 miles per hour throughout.

For reference, on June 25, the windiest day of the year, the daily average wind speed is 5.7 miles per hour, while on January 11, the calmest day of the year, the daily average wind speed is 3.1 miles per hour.

The lowest daily average wind speed during January is 3.1 miles per hour on January 11.

Data Sources

This report illustrates the typical weather in Yangon year round, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016.

Temperature and Dew Point

There is only a single weather station, Yangon International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Yangon.

At a distance of 12 kilometers from Yangon, 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.

The station records are corrected for the elevation difference between the station and Yangon according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Tables of the Sun, Moon and Planets , by Jean Meeus.

All other weather data, including cloud cover, precipitation, wind speed and direction, and solar flux, come from NASA's MERRA-2 Modern-Era Retrospective Analysis . 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.

Land Use data comes from the Global Land Cover SHARE database , published by the Food and Agriculture Organization of the United Nations.

Elevation data comes from the Shuttle Radar Topography Mission (SRTM) , published by NASA's Jet Propulsion Laboratory.
