A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. The chance of wet days in Spirit Lake varies significantly throughout the year.

The wetter season lasts 7.9 months, from October 19 to June 15, with a greater than 26% chance of a given day being a wet day. The chance of a wet day peaks at 43% on November 19.

The drier season lasts 4.1 months, from June 15 to October 19. The smallest chance of a wet day is 9% on August 3.

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 in Spirit Lake changes throughout the year.

Rain alone is the most common for 11 months, from January 10 to December 19. The highest chance of a day with rain alone is 33% on November 10.

Rainfall

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. Spirit Lake experiences significant seasonal variation in monthly rainfall.

Rain falls throughout the year in Spirit Lake. The most rain falls during the 31 days centered around November 18, with an average total accumulation of 3.2 inches.

The least rain falls around August 7, with an average total accumulation of 0.6 inches.

Average Monthly Rainfall

The average rainfall (solid line) accumulated over the course of a sliding 31-day period centered on the day in question, with 25th to 75th and 10th to 90th percentile bands. The thin dotted line is the corresponding average liquid-equivalent snowfall.

Snowfall

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. Colder, drier snow tends to be on the higher end of that range and warmer, wetter snow on the lower end.

As with rainfall, we consider the snowfall accumulated over a sliding 31-day period centered around each day of the year. Spirit Lake experiences significant seasonal variation in monthly liquid-equivalent snowfall.

The snowy period of the year lasts for 5.3 months, from October 24 to April 4, with a sliding 31-day liquid-equivalent snowfall of at least 0.1 inches. The most snow falls during the 31 days centered around December 31, with an average total liquid-equivalent accumulation of 1.3 inches.

The snowless period of the year lasts for 6.6 months, from April 4 to October 24. The least snow falls around July 27, with an average total liquid-equivalent accumulation of 0.0 inches.

The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray. The transitions to and from daylight saving time are indicated by the 'DST' labels.

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 perceived humidity level in Spirit Lake, 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.

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 Spirit Lake does not vary significantly over the course of the year, remaining within 0.2 miles per hour of 4.4 miles per hour throughout.

Solar Energy

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 extreme seasonal variation over the course of the year.

The brighter period of the year lasts for 3.1 months, from May 17 to August 21, with an average daily incident shortwave energy per square meter above 6.2 kWh. The brightest day of the year is July 15, with an average of 7.5 kWh.

Data Sources

This report illustrates the typical weather in Spirit Lake, 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 are 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Spirit Lake.

For each station, the records are corrected for the elevation difference between that station and Spirit Lake 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 Spirit Lake is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Spirit Lake and a given station.

The stations contributing to this reconstruction are: Coeur D'Alene Air Terminal (56%, 23 kilometers, south); Deer Park Airport (23%, 42 kilometers, west); and Sandpoint Airport (21%, 44 kilometers, northeast).

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.

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.
