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 October in Olleros is gradually increasing, starting the month at 0.5 inches, when it rarely exceeds 1.5 inches, and ending the month at 1.0 inches, when it rarely exceeds 2.5 inches. SunOver the course of October in Olleros, the length of the day is gradually increasing. From the start to the end of the month, the length of the day increases by 16 minutes, implying an average daily increase of 31 seconds, and weekly increase of 3 minutes, 37 seconds. The shortest day of the month is October 1, with 12 hours, 11 minutes of daylight and the longest day is October 31, with 12 hours, 27 minutes of daylight. The latest sunrise of the month in Olleros is 5:53 AM on October 1 and the earliest sunrise is 14 minutes earlier at 5:40 AM on October 31. The earliest sunset is 6:04 PM on October 11 and the latest sunset is 2 minutes, 8 seconds later at 6:07 PM on October 31. Daylight saving time is not observed in Olleros during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 5:47 AM and sets 12 hours, 41 minutes later, at 6:29 PM, while on June 20, the shortest day of the year, it rises at 6:24 AM and sets 11 hours, 34 minutes later, at 5:58 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 October 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 Olleros is essentially constant during October, 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 Olleros is essentially constant during October, remaining around 4.9 miles per hour throughout. For reference, on August 1, the windiest day of the year, the daily average wind speed is 5.5 miles per hour, while on March 30, the calmest day of the year, the daily average wind speed is 4.3 miles per hour. The lowest daily average wind speed during October is 4.8 miles per hour on October 11. The hourly average wind direction in Olleros throughout October is predominantly from the east, with a peak proportion of 56% on October 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 in Olleros typically lasts for 10 months (311 days), from around August 10 to around June 17, rarely starting after September 1, or ending before May 18. The month of October in Olleros 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 Olleros are gradually increasing during October, increasing by 128°F, from 383°F to 511°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 Olleros is essentially constant during October, remaining within 0.1 kWh of 6.7 kWh throughout. TopographyFor the purposes of this report, the geographical coordinates of Olleros are -9.633 deg latitude, -77.483 deg longitude, and 11,549 ft elevation.

Data SourcesThis report illustrates the typical weather in Olleros, based on a statistical analysis of historical hourly weather reports and model reconstructions from January 1, 1980 to December 31, 2016. Olleros is further than 200 kilometers from the nearest reliable weather station, so the weather-related data on this page were taken entirely from NASA's MERRA-2 satellite-era reanalysis . 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. The temperature and dew point estimates are corrected for the difference between the reference elevation of the MERRA-2 grid cell and the elevation of Olleros, according to the International Standard Atmosphere . 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. 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.
