Precipitation

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

The wetter season lasts 6.8 months, from April 4 to October 28, with a greater than 43% chance of a given day being a wet day. The chance of a wet day peaks at 82% on August 27.

The drier season lasts 5.2 months, from October 28 to April 4. The smallest chance of a wet day is 3% on December 25.

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 82% on August 27.

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. Lola experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 11 months, from January 28 to December 19, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around August 28, with an average total accumulation of 13.5 inches.

The rainless period of the year lasts for 1.3 months, from December 19 to January 28. The least rain falls around January 11, with an average total accumulation of 0.3 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 Lola does not vary substantially over the course of the year, staying within 34 minutes of 12 hours throughout. In 2017, the shortest day is December 21, with 11 hours, 40 minutes of daylight; the longest day is June 21, with 12 hours, 35 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 6:15 AM on May 26, and the latest sunrise is 38 minutes later at 6:53 AM on January 29. The earliest sunset is at 6:11 PM on November 13, and the latest sunset is 44 minutes later at 6:56 PM on July 14.

Daylight saving time (DST) is not observed in Lola 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.

Lola experiences extreme seasonal variation in the perceived humidity.

The muggier period of the year lasts for 10 months, from February 11 to December 13, during which time the comfort level is muggy, oppressive, or miserable at least 37% of the time. The muggiest day of the year is September 14, with muggy conditions 100% of the time.

The least muggy day of the year is January 2, with muggy conditions 15% of the time.

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

The windier part of the year lasts for 2.4 months, from June 30 to September 11, with average wind speeds of more than 2.4 miles per hour. The windiest day of the year is August 7, with an average hourly wind speed of 3.0 miles per hour.

The calmer time of year lasts for 9.6 months, from September 11 to June 30. The calmest day of the year is October 25, with an average hourly wind speed of 1.8 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 Lola varies throughout the year.

The wind is most often from the east for 2.3 weeks, from January 18 to February 3 and for 2.5 months, from October 23 to January 6, with a peak percentage of 35% on January 18. The wind is most often from the west for 2.4 months, from February 3 to April 14, with a peak percentage of 47% on April 3. The wind is most often from the south for 6.3 months, from April 14 to October 23, with a peak percentage of 63% on June 11.

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 per square meter does not vary significantly over the course of the year, remaining within 0.4 kilowatt-hours of 5.3 kilowatt-hours throughout.

Average Daily Incident Shortwave Solar Energy

The average daily shortwave solar energy reaching the ground per square meter (orange line), with 25th to 75th and 10th to 90th percentile bands.

Data Sources

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

Lola 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 Lola, 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.
