A wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Penrose, the chance of a wet day over the course of the summer is gradually increasing, starting the season at 20% and ending it at 23%.
For reference, the year's highest daily chance of a wet day is 37% on August 10, and its lowest chance is 3% on January 10.
Probability of Precipitation in the Summer in Penrose
To show variation within the season and not just the monthly totals, we show the rainfall accumulated over a sliding 31-day period centered around each day.
The average sliding 31-day rainfall during the summer in Penrose is essentially constant, remaining about 1.4 inches throughout, and rarely exceeding 3.4 inches or falling below 0.2 inches.
The highest average 31-day accumulation is 1.9 inches on August 2.
Average Monthly Rainfall in the Summer in Penrose
Over the course of the summer in Penrose, the length of the day is rapidly decreasing. From the start to the end of the season, the length of the day decreases by 1 hour, 39 minutes, implying an average daily decrease of 1 minute, 5 seconds, and weekly decrease of 7 minutes, 35 seconds.
The shortest day of the summer is August 31, with 13 hours, 2 minutes of daylight and the longest day is June 21, with 14 hours, 51 minutes of daylight.
Hours of Daylight and Twilight in the Summer in Penrose
The earliest sunrise of the summer in Penrose is 5:35 AM on June 13 and the latest sunrise is 53 minutes later at 6:28 AM on August 31.
The latest sunset is 8:28 PM on June 27 and the earliest sunset is 57 minutes earlier at 7:30 PM on August 31.
Daylight saving time is observed in Penrose during 2021, but it neither starts nor ends during the summer, so the entire season is in daylight saving time.
For reference, on June 21, the longest day of the year, the Sun rises at 5:36 AM and sets 14 hours, 51 minutes later, at 8:27 PM, while on December 21, the shortest day of the year, it rises at 7:13 AM and sets 9 hours, 29 minutes later, at 4:42 PM.

The figure below presents a compact representation of key lunar data for the summer of 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.

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 Penrose is essentially constant during the summer, remaining around 0% throughout.

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 Penrose is decreasing during the summer, decreasing from 8.6 miles per hour to 7.0 miles per hour over the course of the season.
For reference, on April 4, the windiest day of the year, the daily average wind speed is 10.0 miles per hour, while on August 13, the calmest day of the year, the daily average wind speed is 6.7 miles per hour.
The lowest daily average wind speed during the summer is 6.7 miles per hour on August 14.

The hourly average wind direction in Penrose throughout the summer is predominantly from the west, with a peak proportion of 45% on June 6.

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 Penrose typically lasts for 5.8 months (176 days), from around April 21 to around October 14, rarely starting before April 1 or after May 10, and rarely ending before September 25 or after November 1.
The summer in Penrose 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 Penrose are very rapidly increasing during the summer, increasing by 1,956°F, from 668°F to 2,624°F, over the course of the season.

This report illustrates the typical weather in Penrose, 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 Penrose.
For each station, the records are corrected for the elevation difference between that station and Penrose 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 Penrose is computed as the weighted average of the individual contributions from each station, with weights proportional to the inverse of the distance between Penrose and a given station.
The stations contributing to this reconstruction are: Butts Army Air Field (KFCS, 48%, 36 kilometers, northeast); Pueblo Memorial Airport (KPUB, 32%, 48 kilometers, east); Wilkerson Pass (K4BM, 4.3%, 82 kilometers, northwest); Harriet Alexander Field Airport (KANK, 10%, 90 kilometers, west); and La Veta Mountain, La Veta Pass (KVTP, 4.9%, 104 kilometers, south).
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.
