For reference, the year's highest daily chance of a wet day is 20% on March 21, and its lowest chance is 1% on July 17. SunOver the course of July in Pallasca, the length of the day is essentially constant. The shortest day of the month is July 1, with 11 hours, 39 minutes of daylight and the longest day is July 31, with 11 hours, 45 minutes of daylight. The latest sunrise of the month in Pallasca is 6:27 AM on July 14 and the earliest sunrise is 1 minute, 47 seconds earlier at 6:25 AM on July 31. The earliest sunset is 6:05 PM on July 1 and the latest sunset is 6 minutes later at 6:11 PM on July 31. Daylight saving time is not observed in Pallasca during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 5:52 AM and sets 12 hours, 36 minutes later, at 6:28 PM, while on June 20, the shortest day of the year, it rises at 6:24 AM and sets 11 hours, 39 minutes later, at 6:03 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 Pallasca is essentially constant during July, remaining around 0% throughout. 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 Pallasca is gradually increasing during July, increasing from 5.1 miles per hour to 5.7 miles per hour over the course of the month. For reference, on July 31, the windiest day of the year, the daily average wind speed is 5.7 miles per hour, while on April 14, the calmest day of the year, the daily average wind speed is 3.5 miles per hour. The hourly average wind direction in Pallasca throughout July is predominantly from the east, with a peak proportion of 62% on July 30. Water TemperaturePallasca 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 Pallasca is essentially constant during July, remaining within 1°F of 64°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). Temperatures in Pallasca are sufficiently warm year round that it is not entirely meaningful to discuss the growing season in these terms. We nevertheless include the chart below as an illustration of the distribution of temperatures experienced throughout the year. 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 Pallasca are gradually increasing during July, increasing by 104°F, from 0°F to 104°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 Pallasca is essentially constant during July, remaining within 0.2 kWh of 6.3 kWh throughout. TopographyFor the purposes of this report, the geographical coordinates of Pallasca are -8.250 deg latitude, -78.017 deg longitude, and 8,494 ft elevation.

Data SourcesThis report illustrates the typical weather in Pallasca, 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, Capitán FAP Carlos Martínez de Pinillos International Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Pallasca. At a distance of 122 kilometers from Pallasca, 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 Pallasca 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.
