The latest sunset is 6:01 PM on May 1 and the earliest sunset is 25 minutes earlier at 5:36 PM on May 31. Daylight saving time is observed in Las Gaviotas 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 6:21 AM and sets 15 hours, 0 minutes later, at 9:21 PM, while on June 20, the shortest day of the year, it rises at 8:14 AM and sets 9 hours, 20 minutes later, at 5:34 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 in Las Gaviotas is essentially constant during May, remaining around 0% throughout. For reference, on March 19, the muggiest day of the year, there are muggy conditions 0% of the time, while on May 4, 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 Las Gaviotas is gradually increasing during May, increasing from 5.2 miles per hour to 5.9 miles per hour over the course of the month. For reference, on July 3, the windiest day of the year, the daily average wind speed is 6.0 miles per hour, while on April 21, the calmest day of the year, the daily average wind speed is 5.1 miles per hour. The hourly average wind direction in Las Gaviotas throughout May is predominantly from the north, with a peak proportion of 43% on May 22. Water TemperatureLas Gaviotas 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 Las Gaviotas is essentially constant during May, remaining within 1°F of 55°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). The growing season in Las Gaviotas typically lasts for 8.0 months (240 days), from around September 13 to around May 11, rarely starting before August 14 or after October 15, and rarely ending before April 11 or after June 12. During May in Las Gaviotas, the chance that a given day is within the growing season is rapidly decreasing falling from 65% to 21% 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 in Las Gaviotas are gradually increasing during May, increasing by 69°F, from 1,634°F to 1,703°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 Las Gaviotas is gradually decreasing during May, falling by 0.9 kWh, from 2.4 kWh to 1.5 kWh, over the course of the month.

Data SourcesThis report illustrates the typical weather in Las Gaviotas, 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, Temuco Maquehue Airport, in our network suitable to be used as a proxy for the historical temperature and dew point records of Las Gaviotas. At a distance of 131 kilometers from Las Gaviotas, 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 Las Gaviotas 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.
