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. Guarenas experiences significant seasonal variation in the perceived humidity. The muggier period of the year lasts for 9.5 months, from March 11 to December 26, during which time the comfort level is muggy, oppressive, or miserable at least 54% of the time. The muggiest day of the year is June 9, with muggy conditions 88% of the time. The least muggy day of the year is January 20, with muggy conditions 42% 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 Guarenas experiences mild seasonal variation over the course of the year. The windier part of the year lasts for 5.5 months, from November 28 to May 12, with average wind speeds of more than 2.9 miles per hour. The windiest day of the year is February 23, with an average hourly wind speed of 3.7 miles per hour. The calmer time of year lasts for 6.5 months, from May 12 to November 28. The calmest day of the year is September 15, with an average hourly wind speed of 2.2 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 Guarenas 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).

Data SourcesThis report illustrates the typical weather in Guarenas, 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 is only a single weather station, Caracas / La Carlota, in our network suitable to be used as a proxy for the historical temperature and dew point records of Guarenas. At a distance of 26 kilometers from Guarenas, 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 Guarenas 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 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.
