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 Moonachie is rapidly increasing during July, rising from 36% to 50% over the course of the month.
For reference, on August 1, the muggiest day of the year, there are muggy conditions 50% of the time, while on December 11, the least muggy day of the year, there are muggy conditions 0% 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 Moonachie is essentially constant during July, remaining within 0.2 miles per hour of 5.5 miles per hour throughout.
For reference, on February 26, the windiest day of the year, the daily average wind speed is 9.2 miles per hour, while on July 31, the calmest day of the year, the daily average wind speed is 5.4 miles per hour.
The lowest daily average wind speed during July is 5.4 miles per hour on July 31.
Average Wind Speed in July
The wind direction in Moonachie during July is predominantly out of the west from July 1 to July 20 and the south from July 20 to July 31.

Definitions of the growing season vary throughout the world, but for the purposes of this report, we define it as the longest continuous period of non-freezing temperatures (≥ 32°F) in the year (the calendar year in the Northern Hemisphere, or from July 1 until June 30 in the Southern Hemisphere).
The growing season in Moonachie typically lasts for 7.2 months (221 days), from around April 1 to around November 9, rarely starting before March 16 or after April 17, and rarely ending before October 21 or after November 27.
The month of July in Moonachie is reliably fully within the growing season.
Time Spent in Various Temperature Bands and the Growing Season in July
Growing degree days are a measure of yearly heat accumulation used to predict plant and animal development, and defined as the integral of warmth above a base temperature, discarding any excess above a maximum temperature. In this report, we use a base of 50°F and a cap of 86°F.
The average accumulated growing degree days in Moonachie are rapidly increasing during July, increasing by 780°F, from 1,256°F to 2,036°F, over the course of the month.

This report illustrates the typical weather in Moonachie 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 are 4 weather stations near enough to contribute to our estimation of the temperature and dew point in Moonachie.
For each station, the records are corrected for the elevation difference between that station and Moonachie 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 Moonachie is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Moonachie and a given station.
The stations contributing to this reconstruction are: Teterboro Airport (91%, 1.7 kilometers, northwest); New York City, Central Park (6%, 9 kilometers, southeast); Newark Liberty International Airport (2.1%, 20 kilometers, southwest); and Westchester County Airport (0.8%, 38 kilometers, northeast).
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.
