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.

Gamarra experiences some seasonal variation in the perceived humidity.

The muggier period of the year lasts for 10 months, from August 13 to June 28, during which time the comfort level is muggy, oppressive, or miserable at least 91% of the time. The muggiest day of the year is November 6, with muggy conditions 99% of the time.

The least muggy day of the year is July 27, with muggy conditions 88% 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 Gamarra does not vary significantly over the course of the year, remaining within 0.4 miles per hour of 1.1 miles per hour throughout.

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 Gamarra varies throughout the year.

The wind is most often from the west for 2.2 months, from August 26 to November 1, with a peak percentage of 47% on September 24. The wind is most often from the north for 3.0 weeks, from November 1 to November 22, with a peak percentage of 41% on November 17. The wind is most often from the east for 9.1 months, from November 22 to August 26, with a peak percentage of 79% on January 1.

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 2.6 months, from January 9 to March 28, with an average daily incident shortwave energy per square meter above 5.6 kWh. The brightest day of the year is February 26, with an average of 6.1 kWh.

The darker period of the year lasts for 2.4 months, from September 18 to November 30, with an average daily incident shortwave energy per square meter below 4.5 kWh. The darkest day of the year is October 16, with an average of 4.1 kWh.

Data Sources

This report illustrates the typical weather in Gamarra, 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, Juan Vicente Gómez International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Gamarra.

At a distance of 153 kilometers from Gamarra, further than our threshold of 150 kilometers, this station is deemed insufficiently nearby to be relied upon as our primary source for temperature and dew point records. Consequently, the station records are blended with interpolated values from NASA's MERRA-2 satellite-era reanalysis , and both are corrected for elevation differences according to the International Standard Atmosphere .

The weight assigned to the MERRA-2 value depends on the distance from Gamarra to the nearest station, increasing from 0% at 150 kilometers to 100% at 200 kilometers. In this case, the MERRA-2 weight is 6%, making the weight assigned to the weather station 94%.

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.
