Sunrise & Sunset with Twilight in July

The solar day over the course of July. From bottom to top, the black lines are the previous solar midnight, sunrise, solar noon, sunset, and the next solar midnight. The day, twilights (civil, nautical, and astronomical), and night are indicated by the color bands from yellow to gray.

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.

The chance that a given day will be muggy in Stony Point is increasing during July, rising from 25% to 35% over the course of the month.

The highest chance of a muggy day during July is 35% on July 28.

For reference, on July 28, the muggiest day of the year, there are muggy conditions 35% of the time, while on November 16, the least muggy day of the year, there are muggy conditions 0% of the time.

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 in Stony Point is essentially constant during July, remaining within 0.2 miles per hour of 4.5 miles per hour throughout.

For reference, on January 15, the windiest day of the year, the daily average wind speed is 6.9 miles per hour, while on August 4, the calmest day of the year, the daily average wind speed is 4.3 miles per hour.

Average Wind Speed in July

The average of mean hourly wind speeds (dark gray line), with 25th to 75th and 10th to 90th percentile bands.
The hourly average wind direction in Stony Point throughout July is predominantly from the west, with a peak proportion of 40% on July 20.

Wind Direction in July

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 Sources

This report illustrates the typical weather in Stony Point 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 5 weather stations near enough to contribute to our estimation of the temperature and dew point in Stony Point.

For each station, the records are corrected for the elevation difference between that station and Stony Point 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 Stony Point is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Stony Point and a given station.

The stations contributing to this reconstruction are: W K Kellogg Airport (36%, 26 kilometers, southeast); Kalamazoo-Battle Creek International Airport (27%, 31 kilometers, south); Gerald R. Ford International Airport (16%, 44 kilometers, north); Fitch H Beach Airport (13%, 51 kilometers, east); and West Michigan Regional Airport (9%, 62 kilometers, northwest).

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.
