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

The wetter season lasts 2.8 months, from June 22 to September 16, with a greater than 41% chance of a given day being a wet day. The chance of a wet day peaks at 78% on August 4.

The drier season lasts 9.2 months, from September 16 to June 22. The smallest chance of a wet day is 2% on December 27.

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 78% on August 4.

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. Mojo experiences extreme seasonal variation in monthly rainfall.

The rainy period of the year lasts for 8.6 months, from February 14 to November 3, with a sliding 31-day rainfall of at least 0.5 inches. The most rain falls during the 31 days centered around August 4, with an average total accumulation of 5.4 inches.

The rainless period of the year lasts for 3.4 months, from November 3 to February 14. The least rain falls around December 23, with an average total accumulation of 0.1 inches.

The length of the day in Mojo does not vary substantially over the course of the year, staying within 37 minutes of 12 hours throughout. In 2017, the shortest day is December 21, with 11 hours, 38 minutes of daylight; the longest day is June 21, with 12 hours, 38 minutes of daylight.

The earliest sunrise is at 6:03 AM on May 27, and the latest sunrise is 41 minutes later at 6:44 AM on January 28. The earliest sunset is at 6:00 PM on November 14, and the latest sunset is 47 minutes later at 6:46 PM on July 13.

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

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 Mojo, 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 Mojo experiences mild seasonal variation over the course of the year.

The windier part of the year lasts for 7.6 months, from October 4 to May 23, with average wind speeds of more than 3.5 miles per hour. The windiest day of the year is November 27, with an average hourly wind speed of 4.5 miles per hour.

The calmer time of year lasts for 4.4 months, from May 23 to October 4. The calmest day of the year is September 12, with an average hourly wind speed of 2.5 miles per hour.

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

The wind is most often from the west for 3.0 months, from June 9 to September 8, with a peak percentage of 77% on July 24. The wind is most often from the east for 9.0 months, from September 8 to June 9, with a peak percentage of 99% 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 1.8 months, from February 5 to March 30, with an average daily incident shortwave energy per square meter above 6.9 kWh. The brightest day of the year is March 2, with an average of 7.3 kWh.

The darker period of the year lasts for 1.5 months, from June 29 to August 12, with an average daily incident shortwave energy per square meter below 5.9 kWh. The darkest day of the year is July 18, with an average of 5.6 kWh.

This report illustrates the typical weather in Mojo, 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 is only a single weather station, Addis Ababa Bole International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Mojo.

At a distance of 56 kilometers from Mojo, closer than our threshold of 150 kilometers, this station is deemed sufficiently nearby to be relied upon as our primary source for temperature and dew point records.

The station records are corrected for the elevation difference between the station and Mojo according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations.

Please note that the station records themselves may additionally have been back-filled using other nearby stations or the MERRA-2 reanalysis.

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.
