CloudsThe winter in Ulapes experiences very rapidly decreasing cloud cover, with the percentage of time that the sky is overcast or mostly cloudy decreasing from 42% to 25%. The clearest day of the winter is August 31, with clear, mostly clear, or partly cloudy conditions 75% of the time. For reference, on May 31, the cloudiest day of the year, the chance of overcast or mostly cloudy conditions is 42%, while on March 15, the clearest day of the year, the chance of clear, mostly clear, or partly cloudy skies is 83%. PrecipitationA wet day is one with at least 0.04 inches of liquid or liquid-equivalent precipitation. In Ulapes, the chance of a wet day over the course of the winter is essentially constant, remaining around 3% throughout. For reference, the year's highest daily chance of a wet day is 39% on January 1, and its lowest chance is 2% on August 10. RainfallTo 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 winter in Ulapes is essentially constant, remaining about 0.2 inches throughout, and rarely exceeding 1.0 inches. The lowest average 31-day accumulation is 0.2 inches on June 15. SunOver the course of the winter in Ulapes, the length of the day is rapidly increasing. From the start to the end of the season, the length of the day increases by 1 hour, 14 minutes, implying an average daily increase of 49 seconds, and weekly increase of 5 minutes, 42 seconds. The shortest day of the winter is June 20, with 10 hours, 5 minutes of daylight and the longest day is August 31, with 11 hours, 27 minutes of daylight. The latest sunrise of the winter in Ulapes is 8:25 AM on July 1 and the earliest sunrise is 43 minutes earlier at 7:41 AM on August 31. The earliest sunset is 6:28 PM on June 10 and the latest sunset is 40 minutes later at 7:08 PM on August 31. Daylight saving time is not observed in Ulapes during 2024. For reference, on December 21, the longest day of the year, the Sun rises at 6:16 AM and sets 14 hours, 13 minutes later, at 8:29 PM, while on June 20, the shortest day of the year, it rises at 8:24 AM and sets 10 hours, 5 minutes later, at 6:29 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 the winter of 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 Ulapes is essentially constant during the winter, remaining around 0% throughout. The lowest chance of a muggy day during the winter is 0% on July 31. For reference, on February 29, the muggiest day of the year, there are muggy conditions 45% of the time, while on July 31, 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 Ulapes is increasing during the winter, increasing from 8.3 miles per hour to 10.0 miles per hour over the course of the season. For reference, on November 6, the windiest day of the year, the daily average wind speed is 11.5 miles per hour, while on June 13, the calmest day of the year, the daily average wind speed is 8.1 miles per hour. The lowest daily average wind speed during the winter is 8.1 miles per hour on June 13. The hourly average wind direction in Ulapes throughout the winter is predominantly from the north, with a peak proportion of 59% on June 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 Ulapes typically lasts for 10 months (306 days), from around August 10 to around June 13, rarely starting before July 17 or after September 7, and rarely ending before May 18 or after July 7. The smallest chance that a given day will be within the growing season in Ulapes during the winter is 8% on July 12. 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 Ulapes are very rapidly decreasing during the winter, decreasing by 5,946°F, from 6,358°F to 412°F, over the course of the season. 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 Ulapes is rapidly increasing during the winter, rising by 1.8 kWh, from 3.3 kWh to 5.0 kWh, over the course of the season. The lowest average daily incident shortwave solar energy during the winter is 3.2 kWh on June 11.

Data SourcesThis report illustrates the typical weather in Ulapes, 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, Villa Dolores Aerodrome, in our network suitable to be used as a proxy for the historical temperature and dew point records of Ulapes. At a distance of 111 kilometers from Ulapes, 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 Ulapes 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.
