HumidityWe 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. Juan Adrián experiences extreme seasonal variation in the perceived humidity. The muggier period of the year lasts for 9.4 months, from March 24 to January 6, during which time the comfort level is muggy, oppressive, or miserable at least 60% of the time. The muggiest day of the year is August 15, with muggy conditions 100% of the time. The least muggy day of the year is February 13, with muggy conditions 47% 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.
WindThis 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 Juan Adrián experiences mild seasonal variation over the course of the year. The windier part of the year lasts for 2.8 months, from June 6 to August 31, with average wind speeds of more than 3.7 miles per hour. The windiest day of the year is July 18, with an average hourly wind speed of 4.3 miles per hour. The calmer time of year lasts for 9.2 months, from August 31 to June 6. The calmest day of the year is October 10, with an average hourly wind speed of 3.1 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 Juan Adrián is from the east throughout the year. 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).
Water TemperatureJuan Adrián 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.

Data SourcesThis report illustrates the typical weather in Juan Adrián, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointThere are 2 weather stations near enough to contribute to our estimation of the temperature and dew point in Juan Adrián. For each station, the records are corrected for the elevation difference between that station and Juan Adrián according to the International Standard Atmosphere , and by the relative change present in the MERRA-2 satellite-era reanalysis between the two locations. The estimated value at Juan Adrián is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Juan Adrián and a given station. The stations contributing to this reconstruction are: Cibao International Airport (54%, 77 kilometers, north) and Las Américas International Airport (46%, 80 kilometers, southeast). Other DataAll 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.
