A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Lhuentse varies very significantly throughout the year.
The wetter season lasts 5.0 months, from April 19 to September 18, with a greater than 35% chance of a given day being a wet day. The chance of a wet day peaks at 68% on July 18.
The drier season lasts 7.0 months, from September 18 to April 19. The smallest chance of a wet day is 1% on December 1.
Among wet days, we distinguish between those that experience rain alone, snow alone, or a mixture of the two. Based on this categorization, the most common form of precipitation throughout the year is rain alone, with a peak probability of 68% on July 18.
Daily Chance of Precipitation
To show variation within the months and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day of the year. Lhuentse experiences extreme seasonal variation in monthly rainfall.

Sunrise & Sunset with Twilight
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 perceived humidity level in Lhuentse, as measured by the percentage of time in which the humidity comfort level is muggy, oppressive, or miserable, does not vary significantly over the course of the year, remaining a virtually constant 0% throughout.

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 Lhuentse does not vary significantly over the course of the year, remaining within 0.5 miles per hour of 2.4 miles per hour throughout.
Average Wind Speed
The predominant average hourly wind direction in Lhuentse varies throughout the year.
The wind is most often from the north for 2.6 weeks, from December 11 to December 29, with a peak percentage of 48% on December 16. The wind is most often from the south for 11 months, from December 29 to December 11, with a peak percentage of 46% on January 1.
This section discusses the total daily incident shortwave solar energy reaching the surface of the ground over a wide area, taking full account of seasonal variations in the length of the day, the elevation of the Sun above the horizon, and absorption by clouds and other atmospheric constituents. Shortwave radiation includes visible light and ultraviolet radiation.
The average daily incident shortwave solar energy experiences some seasonal variation over the course of the year.
The brighter period of the year lasts for 3.0 months, from March 12 to June 11, with an average daily incident shortwave energy per square meter above 6.4 kWh. The brightest day of the year is April 15, with an average of 7.0 kWh.
The darker period of the year lasts for 2.5 months, from November 10 to January 25, with an average daily incident shortwave energy per square meter below 4.9 kWh. The darkest day of the year is December 19, with an average of 4.4 kWh.

Temperature and Dew Point
There is only a single weather station, Lokpriya Gopinath Bordoloi International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Lhuentse.
At a distance of 178 kilometers from Lhuentse, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .
The weight assigned to the MERRA-2 value depends on the distance from Lhuentse to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 36%, making the weight assigned to the weather station 64%.
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.
