Precipitation

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

The wetter season lasts 4.8 months, from May 21 to October 14, with a greater than 47% chance of a given day being a wet day. The chance of a wet day peaks at 94% on August 16.

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 94% on August 16.

Daily Chance of Precipitation

The percentage of days in which various types of precipitation are observed, excluding trace quantities: rain alone, snow alone, and mixed (both rain and snow fell in the same day).

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. Labé experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 7.4 months, from April 7 to November 18, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around August 16, with an average total accumulation of 17.5 inches.

The rainless period of the year lasts for 4.6 months, from November 18 to April 7. The least rain falls around December 31, with an average total accumulation of 0.0 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.

Sun

The length of the day in Labé does not vary substantially over the course of the year, staying within 47 minutes of 12 hours throughout. In 2017, the shortest day is December 21, with 11 hours, 28 minutes of daylight; the longest day is June 21, with 12 hours, 47 minutes of daylight.

Hours of Daylight and Twilight

The number of hours during which the Sun is visible (black line). From bottom (most yellow) to top (most gray), the color bands indicate: full daylight, twilight (civil, nautical, and astronomical), and full night.

The earliest sunrise is at 6:24 AM on May 30, and the latest sunrise is 49 minutes later at 7:13 AM on January 25. The earliest sunset is at 6:21 PM on November 18, and the latest sunset is 55 minutes later at 7:16 PM on July 11.

Daylight saving time (DST) is not observed in Labé during 2017.

Sunrise & Sunset with Twilight

The solar day over the course of the year 2017. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray.

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.

Labé experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 6.1 months, from May 7 to November 11, during which time the comfort level is muggy, oppressive, or miserable at least 24% of the time. The muggiest day of the year is August 17, with muggy conditions 92% of the time.

The least muggy day of the year is January 21, when muggy conditions are essentially unheard of.

Humidity Comfort Levels

The percentage of time spent at various humidity comfort levels, categorized by dew point: dry < 55°F < comfortable < 60°F < humid < 65°F < muggy < 70°F < oppressive < 75°F < miserable.

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 Labé experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 5.5 months, from November 30 to May 16, with average wind speeds of more than 3.1 miles per hour. The windiest day of the year is January 14, with an average hourly wind speed of 3.7 miles per hour.

The calmer time of year lasts for 6.5 months, from May 16 to November 30. The calmest day of the year is October 16, with an average hourly wind speed of 2.5 miles per hour.

Average Wind Speed

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.

The predominant average hourly wind direction in Labé varies throughout the year.

The wind is most often from the north for 1.4 weeks, from March 15 to March 25, with a peak percentage of 33% on March 21. The wind is most often from the west for 5.5 months, from March 25 to September 11, with a peak percentage of 55% on August 9. The wind is most often from the east for 6.1 months, from September 11 to March 15, with a peak percentage of 79% on January 1.

Wind Direction

The percentage of hours in which the mean wind direction is from each of the four cardinal wind directions (north, east, south, and west), excluding hours in which the mean wind speed is less than 1 mph. The lightly tinted areas at the boundaries are the percentage of hours spent in the implied intermediate directions (northeast, southeast, southwest, and northwest).

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 some seasonal variation over the course of the year.

The brighter period of the year lasts for 2.4 months, from February 14 to April 25, with an average daily incident shortwave energy per square meter above 6.3 kWh. The brightest day of the year is March 27, with an average of 6.8 kWh.

The darker period of the year lasts for 2.7 months, from June 26 to September 17, with an average daily incident shortwave energy per square meter below 5.0 kWh. The darkest day of the year is August 9, with an average of 4.6 kWh.

Average Daily Incident Shortwave Solar Energy

Data Sources

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

Labé is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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.

The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Labé, according to the International Standard Atmosphere .

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.

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.
