May Weather at Aeródromo El Loa ChileDaily high temperatures decrease by 2°F, from 72°F to 69°F, rarely falling below 64°F or exceeding 76°F. Daily low temperatures decrease by 4°F, from 41°F to 38°F, rarely falling below 33°F or exceeding 46°F. For reference, on December 24, the hottest day of the year, temperatures at Aeródromo El Loa typically range from 46°F to 76°F, while on July 11, the coldest day of the year, they range from 35°F to 68°F. The figure below shows you a compact characterization of the hourly average temperatures for the quarter of the year centered on May. 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. Rancho Alegre, Mexico (3,579 miles away) is the far-away foreign place with temperatures most similar to Aeródromo El Loa (view comparison). CloudsThe month of May at Aeródromo El Loa experiences essentially constant cloud cover, with the percentage of time that the sky is overcast or mostly cloudy remaining about 25% throughout the month. The clearest day of the month is May 27, with clear, mostly clear, or partly cloudy conditions 76% of the time. For reference, on January 7, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 38%, while on August 29, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 86%. PrecipitationSunOver the course of May at Aeródromo El Loa, the length of the day is gradually decreasing. From the start to the end of the month, the length of the day decreases by 25 minutes, implying an average daily decrease of 49 seconds, and weekly decrease of 5 minutes, 43 seconds. The shortest day of the month is May 31, with 10 hours, 51 minutes of daylight and the longest day is May 1, with 11 hours, 15 minutes of daylight. The earliest sunrise of the month at Aeródromo El Loa is 6:54 AM on May 1 and the latest sunrise is 13 minutes later at 7:08 AM on May 31. The latest sunset is 6:10 PM on May 1 and the earliest sunset is 11 minutes earlier at 5:58 PM on May 31. Daylight saving time is observed at Aeródromo El Loa during 2024, but it neither starts nor ends during May, so the entire month is in daylight saving time. For reference, on December 21, the longest day of the year, the Sun rises at 6:48 AM and sets 13 hours, 31 minutes later, at 8:19 PM, while on June 20, the shortest day of the year, it rises at 7:14 AM and sets 10 hours, 45 minutes later, at 6:00 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 May 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 at Aeródromo El Loa is essentially constant during May, 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 at Aeródromo El Loa is essentially constant during May, remaining within 0.2 miles per hour of 8.2 miles per hour throughout. For reference, on September 20, the windiest day of the year, the daily average wind speed is 9.2 miles per hour, while on April 5, the calmest day of the year, the daily average wind speed is 7.8 miles per hour. The hourly average wind direction at Aeródromo El Loa throughout May is predominantly from the west, with a peak proportion of 41% on May 1. 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 at Aeródromo El Loa typically lasts for 8.9 months (269 days), from around September 7 to around June 3, rarely starting before July 31 or after October 12, and rarely ending before May 11 or after June 27. The month of May at Aeródromo El Loa is more likely than not fully within the growing season, with the chance that a given day is in the growing season rapidly decreasing from 95% to 57% over the course of the month. 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 at Aeródromo El Loa are increasing during May, increasing by 220°F, from 3,083°F to 3,303°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 at Aeródromo El Loa is gradually decreasing during May, falling by 0.8 kWh, from 6.0 kWh to 5.2 kWh, over the course of the month. Data SourcesThis report illustrates the typical weather at Aeródromo El Loa, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Temperature and Dew PointAeródromo El Loa has a weather station that reported reliably enough during the analysis period that we have included it in our network. When available, historical temperature and dew point measurements are taken directly from this weather station. These records are obtained from NOAA's Integrated Surface Hourly data set, falling back on ICAO METAR records as required. There are no other weather stations in our network within 200 kilometers of this location. Consequently, in the case of missing or erroneous measurements from this station, we fall back on NASA's MERRA-2 modern-era reanalysis , adjusted according to typical seasonal and diurnal differences between this station and the wide-area MERRA-2 reconstructed values.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.
