A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Managua, the chance of a wet day over the course of August is very rapidly increasing, starting the month at 24% and ending it at 36%.

For reference, the year's highest daily chance of a wet day is 43% on September 18, and its lowest chance is 0% on January 8.

Rainfall

To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.

The average sliding 31-day rainfall during August in Managua is very rapidly increasing, starting the month at 2.7 inches, when it rarely exceeds 6.6 inches or falls below 0.4 inches, and ending the month at 5.4 inches, when it rarely exceeds 11.8 inches or falls below 0.8 inches.

Over the course of August in Managua, the length of the day is gradually decreasing. From the start to the end of the month, the length of the day decreases by 18 minutes, implying an average daily decrease of 35 seconds, and weekly decrease of 4 minutes, 6 seconds.

The shortest day of the month is August 31, with 12 hours, 21 minutes of daylight and the longest day is August 1, with 12 hours, 39 minutes of daylight.

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 Managua is essentially constant during August, remaining around 99% throughout.

For reference, on September 18, the muggiest day of the year, there are muggy conditions 100% of the time, while on January 31, the least muggy day of the year, there are muggy conditions 64% of the time.

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 Managua is decreasing during August, decreasing from 6.4 miles per hour to 5.1 miles per hour over the course of the month.

For reference, on February 6, the windiest day of the year, the daily average wind speed is 8.3 miles per hour, while on October 3, the calmest day of the year, the daily average wind speed is 4.3 miles per hour.

Managua is located near a large body of water (e.g., ocean, sea, or large lake). This section reports on the wide-area average surface temperature of that water.

The average surface water temperature in Managua is essentially constant during August, remaining around 84°F throughout.

The highest average surface water temperature during August is 84°F on August 25.

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 in Managua is essentially constant during August, remaining within 0.1 kWh of 5.2 kWh throughout.

The highest average daily incident shortwave solar energy during August is 5.3 kWh on August 10.

This report illustrates the typical weather in Managua year round, 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, Augusto César Sandino International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Managua.

At a distance of 9 kilometers from Managua, 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 Managua 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.
