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.

Muggy conditions are essentially unheard-of at Carrasco International Airport on September 19.

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 at Carrasco International Airport on September 19 varies throughout the day, with a daily average of 12.1 miles per hour.

The windiest time of day is around 9:15 AM, with an average hourly wind speed of 12.7 miles per hour, mostly staying between 9.1 miles per hour and 15.8 miles per hour, and rarely falling below 5.9 miles per hour or exceeding 19.7 miles per hour.

The calmest time of day is around 6:30 PM, with an average hourly wind speed of 11.1 miles per hour, mostly staying between 7.3 miles per hour and 14.4 miles per hour, and rarely falling below 4.6 miles per hour or exceeding 18.4 miles per hour.

For reference, on November 12, the windiest day of the year, the daily average wind speed is 12.3 miles per hour, while on May 6, the calmest day of the year, the daily average wind speed is 10.9 miles per hour.

Water Temperature

Carrasco International Airport 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 does not change appreciably over the course of the day, so this section does not include a chart.

The average surface water temperature on September 19 at Carrasco International Airport is 56°F, mostly staying between 55°F and 57°F, and rarely falling below 53°F or exceeding 58°F.

For reference, the year's highest average is 74°F on January 26, and its lowest average is 52°F on July 25.

Shortwave Solar Power

This section discusses the incident shortwave solar power 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 peak incident shortwave solar power per square meter is 0.68 kilowatts at around 12:45 PM.

In contrast, the corresponding value on January 1, the brightest day of the year, is 0.95 kilowatts at around 12:15 PM. The corresponding value on June 20, the darkest day of the year, is 0.40 kilowatts at around 11:45 AM.

Data Sources

This report illustrates the typical weather at Carrasco International Airport, 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

Carrasco International Airport has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required.

In the case of missing or erroneous measurements from this station, we fall back on records from nearby stations, adjusted according to typical seasonal and diurnal intra-station differences. For a given day of the year and hour of the day, the fallback station is selected to minimize the prediction error over the years for which there are measurements for both stations.

The stations on which we may fall back are Capitán de Corbeta Carlos A. Curbelo International Airport and Colonia del Sacramento International Airport.

Other Data

All data relating to the Sun's position (e.g., sunrise and sunset) are computed using astronomical formulas from the book, Astronomical Algorithms 2nd Edition , 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.

We draw particular cautious attention to our reliance on the MERRA-2 model-based reconstructions for a number of important data series. While having the tremendous advantages of temporal and spatial completeness, these reconstructions: (1) are based on computer models that may have model-based errors, (2) are coarsely sampled on a 50 km grid and are therefore unable to reconstruct the local variations of many microclimates, and (3) have particular difficulty with the weather in some coastal areas, especially small islands.

We further caution that our travel scores are only as good as the data that underpin them, that weather conditions at any given location and time are unpredictable and variable, and that the definition of the scores reflects a particular set of preferences that may not agree with those of any particular reader.
