The average sliding 31-day rainfall during January in La Pine is gradually decreasing, starting the month at 2.4 inches, when it rarely exceeds 4.7 inches or falls below 0.5 inches, and ending the month at 2.0 inches, when it rarely exceeds 4.2 inches or falls below 0.3 inches.
Average Monthly Rainfall in January
We report snowfall in liquid-equivalent terms. The actual depth of new snowfall is typically between 5 and 10 times the liquid-equivalent amount, assuming the ground is frozen. As with rainfall, we consider the liquid-equivalent snowfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day liquid-equivalent snowfall during January in La Pine is gradually decreasing, starting the month at 1.0 inches, when it rarely exceeds 2.4 inches or falls below 0.1 inches, and ending the month at 0.7 inches, when it rarely exceeds 1.7 inches.

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 La Pine is essentially constant during January, remaining around 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 La Pine is essentially constant during January, remaining around 3.4 miles per hour throughout.
For reference, on December 1, the windiest day of the year, the daily average wind speed is 3.5 miles per hour, while on August 3, the calmest day of the year, the daily average wind speed is 2.4 miles per hour.
The lowest daily average wind speed during January is 3.3 miles per hour on January 30.

Temperature and Dew Point
There are 6 weather stations near enough to contribute to our estimation of the temperature and dew point in La Pine.
For each station, the records are corrected for the elevation difference between that station and La Pine according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.
The estimated value at La Pine is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between La Pine and a given station.
The stations contributing to this reconstruction are: Bend Municipal Airport (54%, 53 kilometers, northeast); Mahlon Sweet Field Airport (9%, 147 kilometers, west); Roseburg Municipal Airport (9%, 157 kilometers, west); Klamath Falls Airport (11%, 171 kilometers, south); Rogue Valley International - Medford Airport (8%, 182 kilometers, southwest); and Lake County-Lakeview Airport (9%, 190 kilometers, southeast).
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.
