Probability of Precipitation in July
To show variation within the month and not just the monthly total, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during July in Dobson is essentially constant, remaining about 3.4 inches throughout, and rarely exceeding 5.7 inches or falling below 1.6 inches.
Average Monthly Rainfall in July
Over the course of July in Dobson, the length of the day is decreasing. From the start to the end of the month, the length of the day decreases by 36 minutes, implying an average daily decrease of 1 minute, 11 seconds, and weekly decrease of 8 minutes, 18 seconds.
The shortest day of the month is July 31, with 14 hours, 0 minutes of daylight and the longest day is July 1, with 14 hours, 36 minutes of daylight.
Hours of Daylight and Twilight in July
The earliest sunrise of the month in Dobson is 6:08 AM on July 1 and the latest sunrise is 20 minutes later at 6:28 AM on July 31.
The latest sunset is 8:44 PM on July 1 and the earliest sunset is 16 minutes earlier at 8:29 PM on July 31.
Daylight saving time is observed in Dobson during 2021, but it neither starts nor ends during July, so the entire month is in daylight saving time.
For reference, on June 21, the longest day of the year, the Sun rises at 6:05 AM and sets 14 hours, 39 minutes later, at 8:44 PM, while on December 21, the shortest day of the year, it rises at 7:30 AM and sets 9 hours, 41 minutes later, at 5:11 PM.

The figure below presents a compact representation of key lunar data for July 2021. The horizontal axis is the day, the vertical axis is the hour of the day, and the colored areas indicate when the moon is above the horizon. The vertical gray bars (new Moons) and blue bars (full Moons) indicate key Moon phases. The label associated with each bar indicates the date and time that the phase is obtained, and the companion time labels indicate the rise and set times of the Moon for the nearest time interval in which the moon is above the horizon.
Moon Rise, Set & Phases in July
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 Dobson is rapidly increasing during July, rising from 63% to 75% over the course of the month.
The highest chance of a muggy day during July is 77% on July 25.
For reference, on July 24, the muggiest day of the year, there are muggy conditions 77% of the time, while on January 24, 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 Dobson is essentially constant during July, remaining within 0.2 miles per hour of 4.4 miles per hour throughout.
For reference, on March 8, the windiest day of the year, the daily average wind speed is 7.3 miles per hour, while on August 1, the calmest day of the year, the daily average wind speed is 4.3 miles per hour.
Average Wind Speed in July
The hourly average wind direction in Dobson throughout July is predominantly from the west, with a peak proportion of 39% on July 13.

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 Dobson typically lasts for 7.3 months (223 days), from around March 30 to around November 7, rarely starting before March 9 or after April 21, and rarely ending before October 19 or after November 27.
The month of July in Dobson 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 Dobson are rapidly increasing during July, increasing by 793°F, from 1,725°F to 2,518°F, over the course of the month.

This section discusses the total daily incident shortwave solar energy 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 average daily incident shortwave solar energy in Dobson is essentially constant during July, remaining within 0.2 kWh of 6.7 kWh throughout.

This report illustrates the typical weather in Dobson, 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 3 weather stations near enough to contribute to our estimation of the temperature and dew point in Dobson.
For each station, the records are corrected for the elevation difference between that station and Dobson 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 Dobson is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Dobson and a given station.
The stations contributing to this reconstruction are: Mount Airy/Surry County Airport (70%, 17 kilometers, northeast); North Wilkesboro, Wilkes County Airport (20%, 39 kilometers, southwest); and Hillsville (10%, 42 kilometers, north).
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.
