July Weather in Graham United StatesDaily high temperatures increase by 5°F, from 75°F to 80°F, rarely falling below 65°F or exceeding 90°F. Daily low temperatures increase by 2°F, from 51°F to 54°F, rarely falling below 46°F or exceeding 59°F. For reference, on August 2, the hottest day of the year, temperatures in Graham typically range from 54°F to 80°F, while on December 31, the coldest day of the year, they range from 35°F to 46°F. The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on July. The horizontal axis is the day, the vertical axis is the hour of the day, and the color is the average temperature for that hour and day. Blancos, Spain (5,103 miles away) is the far-away foreign place with temperatures most similar to Graham (view comparison). CloudsThe month of July in Graham experiences rapidly decreasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy decreasing from 40% to 25%. The clearest day of the month is July 31, with clear, mostly clear, or partly cloudy conditions 75% of the time. For reference, on November 29, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 77%, while on August 2, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 76%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Graham, the chance of a wet day over the course of July is very rapidly decreasing, starting the month at 17% and ending it at 8%. For reference, the year's highest daily chance of a wet day is 59% on November 16, and its lowest chance is 7% on August 4. RainfallTo 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 Graham is decreasing, starting the month at 1.1 inches, when it rarely exceeds 2.1 inches or falls below 0.2 inches, and ending the month at 0.5 inches, when it rarely exceeds 1.4 inches. The lowest average 31-day accumulation is 0.5 inches on July 29. SunOver the course of July in Graham, the length of the day is decreasing. From the start to the end of the month, the length of the day decreases by 55 minutes, implying an average daily decrease of 1 minute, 51 seconds, and weekly decrease of 12 minutes, 54 seconds. The shortest day of the month is July 31, with 14 hours, 54 minutes of daylight and the longest day is July 1, with 15 hours, 50 minutes of daylight. The earliest sunrise of the month in Graham is 5:18 AM on July 1 and the latest sunrise is 30 minutes later at 5:48 AM on July 31. The latest sunset is 9:07 PM on July 1 and the earliest sunset is 26 minutes earlier at 8:42 PM on July 31. Daylight saving time is observed in Graham during 2024, but it neither starts nor ends during July, so the entire month is in standard time. For reference, on June 20, the longest day of the year, the Sun rises at 5:13 AM and sets 15 hours, 54 minutes later, at 9:08 PM, while on December 21, the shortest day of the year, it rises at 7:52 AM and sets 8 hours, 30 minutes later, at 4:22 PM. The figure below presents a compact representation of the sun's elevation (the angle of the sun above the horizon) and azimuth (its compass bearing) for every hour of every day in the reporting period. The horizontal axis is the day of the year and the vertical axis is the hour of the day. For a given day and hour of that day, the background color indicates the azimuth of the sun at that moment. The black isolines are contours of constant solar elevation. MoonThe figure below presents a compact representation of key lunar data for July 2024. 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.
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. The chance that a given day will be muggy in Graham is essentially constant during July, remaining around 0% throughout. For reference, on July 31, the muggiest day of the year, there are muggy conditions 0% of the time, while on January 1, the least muggy day of the year, there are muggy conditions 0% of the time. 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 Graham is essentially constant during July, remaining within 0.1 miles per hour of 3.3 miles per hour throughout. For reference, on December 2, the windiest day of the year, the daily average wind speed is 5.3 miles per hour, while on August 1, the calmest day of the year, the daily average wind speed is 3.2 miles per hour. The hourly average wind direction in Graham throughout July is predominantly from the west, with a peak proportion of 52% on July 1. Water TemperatureGraham 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. The average surface water temperature in Graham is essentially constant during July, remaining within 1°F of 56°F throughout. Growing SeasonDefinitions 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 Graham typically lasts for 6.2 months (190 days), from around April 17 to around October 23, rarely starting before March 28 or after May 8, and rarely ending before October 4 or after November 12. The month of July in Graham is reliably fully within the growing season. 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 Graham are increasing during July, increasing by 422°F, from 626°F to 1,048°F, over the course of the month. Solar EnergyThis 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 Graham is essentially constant during July, remaining within 0.1 kWh of 6.8 kWh throughout. The highest average daily incident shortwave solar energy during July is 6.9 kWh on July 20.

Data SourcesThis report illustrates the typical weather in Graham, 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, Pierce County Airport Thun Field, in our network suitable to be used as a proxy for the historical temperature and dew point records of Graham. At a distance of 6 kilometers from Graham, 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 Graham 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 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.

Weather data is prone to errors, outages, and other defects. We assume no responsibility for any decisions made on the basis of the content presented on this site. 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.
